Gloves are mainly used to protect the skin from harm in People's Daily activities and special environments, and can also be used to play a decorative role in daily life.According to the different production methods, it is divided into knitted gloves, sewing gloves, soaked gloves and so on. Depending on the function, there are flame retardant gloves, welding gloves, non-slip gloves, oil resistant gloves, acid and alkali resistant gloves, medical gloves, heat resistant gloves, thermal gloves, boxing gloves, work gloves, ski gloves, guardian gloves, protective gloves, ceremonial gloves, aerospace gloves, labor protection gloves and so on. The main materials for making gloves are various rubber, leather, plastic, fiber and so on. Untreated rubber and plastic gloves have the disadvantages of being difficult to remove and not easy to wear. The traditional treatment method is to coat the surface of the gloves with a layer of lubricating materials (such as starch, talc powder, etc.) to increase the wearability and release of the gloves. However, powder lubricants can cause pollution during production and use, and may cause allergic reactions in some people, so the use of powder gloves is gradually decreasing. At present, waterborne polyurethane (WPU) finishing agent has been used to coat the inner layer of gloves in place of powder lubricants such as starch or talc. The production process of waterborne polyurethane glove finishing agent is simple, the emulsion stability is good, and the film forming elasticity and puncture resistance are excellent. Waterborne polyurethane not only has the advantages of non-toxic, non-polluting environment, not easy to burn, safe and reliable, not easy to damage the coated surface, energy saving, easy to operate and easy to modify, but also has good solvent resistance, wear resistance, flexibility and thermal stability. It has been widely used in the fields of leather coating, fabric, adhesive and coating. Waterborne polyurethane has the following main applications in the glove industry. 1.Unlined gloves, directly using waterborne polyurethane film; 2.Powder-free PVC gloves are coated with a water-based polyurethane film inside the PVC; 3.Natural rubber gloves and PVC household gloves inner layer electrostatic flocking waterborne polyurethane glue; 4.Protective gloves, in the non-woven gloves, knitted gloves or fingertips coated with water-based polyurethane film has achieved labor protection. Sinograce Chemical has waterborne polyurethane emulsion for disposable glove raw materials, and water based polyurethane emulsion for labor protection gloves coating.

Aqueous acrylic emulsion High viscosity is a monomer polymerization emulsion with good self-crosslinking performance, which helps to improve the density and water resistance of the film. The high hardness ensures the stability of the coating under external physical impact, and the high solid content increases the covering power of the coating and reduces the number of construction. Alkali resistant, moisture-proof, mildew resistant can improve the environmental adaptability of the paint, prolong the service life. It has good adhesion to a variety of materials, especially in the construction industry where coatings are used in large quantities.

Water-based glass paint Does not contain benzene, esters and other harmful solvents, does not contain free TDI, does not burn, is the latest environmental protection glass process paint, by the international and other authoritative verification institutions assessed as the real green environmental protection products. Address the problem It is required to blister at 75℃ for 30 minutes and it is required to be dense. Soak in ethanol for 48 hours without fading. Varnish reference formula Varnish: water-based resin, deionized water, defoamer, leveling agent, etc Water-based glass paint is a water-based paint used on glass substrates. At present, there are single-component self-drying type, single-component baking type, two-component self-drying type. Single-component self-drying type is prepared by water-based polyurethane emulsion and adhesion enhancer; The one-component baked type is prepared by emulsion containing -OH or carboxyl group and water-dilutive amino resin;The principle corresponds to oil-based baking paint. The two-component self-drying type is composed of water-based epoxy resin plus binary amines, etc., and the principle corresponds to the two-component self-drying paint, such as epoxy floor paint, two-component PU paint, etc. Pure water-based glass paint belongs to water-based glass paint. 1.water-based glass paint water as a diluent, and oily glass paint generally use banana oil to do diluent, everyone knows that banana oil is toxic, from this point of view water-based glass paint is more environmentally friendly and safe than oily glass paint, and when cleaning the spray gun and mold with water-based glass paint, you can clean it with water. And the use of oil-based glass paint, usually use the banana oil to clean the spray gun and the like. 2. The aging resistance of water-based glass paint is stronger than that of oil-based glass paint. 3. In terms of adhesion, water-based glass paint is better than oil-based glass paint. 4. Water based resin is more expensive than oil based resin

R & D, production and sales of various acrylic emulsion, white latex, woodworking adhesive series, waterborne polyurethane dispersion, etc., used in packaging film, waterborne paint, wood paint, waterborne metal anti-corrosion paint, waterborne plastic paint one and two components, leather coating agent, printing ink and light oil, waterborne composite ink adhesion level 0, laminating glue, laminating glue, plywood glue, PVC adhesive, textile stiffening agent, etc. Printing glue, pressure sensitive adhesive PSA, etc. Exchanges and cooperation are welcome 1.Improve water resistance of acrylic emulsion (1)Utilization of hydrosol Hydrosol is a polymeric dispersion of very small particles, which has the characteristics of both emulsion system and solution system, and can effectively improve water resistance (2)Reduce the amount of emulsifier Although the emulsifier plays an important role in the formation of micelles in polymerization and the stability of the emulsion after polymerization, it is also an important reason for the decrease of water resistance and adhesion. Using special emulsifiers or reducing the amount of emulsifiers can help to improve the water resistance of the emulsion. 2.Improve the adhesive strength (adhesion) of acrylic emulsion (1)The addition of viscosifying resin It can significantly improve the 180° peel strength and initial adhesion of the pressure-sensitive adhesive, and there are two ways to add it: First, blending, using this method to increase the viscosity of the resin must meet three basic requirements: a.Its molecular weight must be lower than the molecular weight of the adhesive polymer b.The glass transition temperature of the tackifying resin must be higher than that of the polymer c.The compatibility of the adhesive resin with the adhesive polymer to be added is betterSecond, before the emulsion polymerization, the tackifying resin is dissolved in the acrylate monomer in advance, and then the emulsion polymerization can also prepare the adhesive with good comprehensive properties. (2)Select different polymerization methods If using core-shell polymerization. The core of the polymer uses a harder monomer such as styrene, acrylonitrile, methacrylate, etc., while the shell of the polymer uses a softer alkyl acrylate monomer, so that the polymer emulsion with this structure can greatly improve the cohesion strength of the adhesive. Special monomer, such as copolymerization of acrylic monomer with appropriate amount of isononyl acrylate (Tg=82℃), can further improve its comprehensive properties. In order to improve the bonding of alkane materials, vinyl benzoate, tetrahydrofurfuryl methacrylate, cyclohexyl acrylate, 2-phenoxyethyl acrylate and other monomers can be copolymerized with alkyl acrylate to improve the wettability of non-polar bonded bodies and effectively improve the bonding force.
