This product uses butadiene, Acrylonitrile as the main raw materials, through emulsion polymerization of anionic polymer dispersion, can be used to produce disposable medical examination gloves, with excellent elongation and tensile strength The product is an environmentally friendly product, free of formaldehyde, APEO, NPEO and other harmful substances, and has excellent elongation, tensile strength and excellent chemical resistance, puncture resistance, weather resistance and other properties; It can be used to produce disposable medical examination gloves. Acrylonitrile butadiene rubber latex (NBRL) is an emulsion dispersion formed by random copolymerization of butadiene and unsaturated nitrile monomers. In order to improve the film formation, adhesion, toughness and other physical and mechanical properties of butadiene latex, the polymer chain of polybutadiene-acrylonitrile was modified by the third monomer containing carboxyl such as methacrylic acid or the fourth functional monomer such as unsaturated carboxylic acid esters, and the carboxylic butadienitrile latex series products were produced. Nitrile latex is mainly used in impregnated gloves (medical and non-medical), oil resistant hose, oil resistant sponge and other rubber products, as well as non-woven fabrics, carpet backing and paper processing and other non-rubber products. The application of nitrile latex is more and more widely, the technology is constantly improved, and the varieties are increasingly listed. With the development of carboxy butadiene latex synthesis technology and the maturity of its downstream product production process, the demand for carboxy butadiene latex is increasing, and manufacturers of butadiene latex have a very bright market development prospect.

Styrene-butadiene rubber latex is a kind of copolymer emulsion obtained by emulsion polymerization with butadiene and styrene as monomers or main monomers. Ordinary styrene butadiene latex Carboxylic butadiene-styrene latex Bufedipine latex There are many varieties of styrene-butadiene latex, according to the different types of raw materials can be divided into ordinary styrene-butadiene latex, carboxy styrene-butadiene latex and burene-butadiene latex three types, of which the carboxy styrene-butadiene latex production capacity is the largest, a wide range of applications, and the production of burene-burene-styrene latex is small, narrow application field, mainly used in the rubber bonding fiber cord cloth of the adhesive system, Butadiene latex is styrene, butadiene and vinyl pyridine of the ternary copolymer latex, generally also belongs to butadiene latex series A variety of brands of styrene butadiene latex have been formed according to the different content of bound styrene, the different types of carboxylic acid monomer and the different content of solid substances in latex. Although its physical performance parameters are repeated, its application fields have also been subdivided. The styrene content of common type SBRL is generally about 25%, and there are also intermediate styrene SBRL with styrene content of about 30%. Combined styrene content is more than 45%, mostly carboxylated styrene butadiene latex, other non-carboxylated high styrene content latex and carboxylated low styrene content latex. Under normal conditions, the solid content of about 40% styrene butadiene latex is mainly used for asphalt modification and adhesive; The carboxyl-butadiene latex with solid content of 50% is mainly used for paper coating and carpet back coating; SBRL and XSBRL with solid content greater than 60% are mainly used as sponge products. SBRL with styrene content greater than 80% is generally not used alone and can be used as a regulator of hardness of other latex film. Bubenopyrene latex and SBRL with high solid content can be used as cord adhesives for rubber tires.

Three synthetic latex common and characteristic Compared with natural latex, the commonality of synthetic latex lies in its excellent storage stability, mechanical stability, chemical stability and freeze-thaw stability during storage and application. The characteristics of different kinds of synthetic latex are as follows: Styrene-butadiene latex Butadiene series latex is a copolymer latex synthesized mainly by butadiene and styrene monomer. Butadiene gives the adhesive and resilience of latex, and styrene makes the polymer film have certain plasticity and stiffness. The difference in the ratio of the two can change the film forming temperature and glass transition temperature. The introduction of unsaturated carboxylic acid monomer enhanced the stability and adhesion of latex. Its advantages are a wide range of applications, low production costs; The disadvantage is poor resistance to chemicals and solvents. Butadiene-acrylonitrile latex Butadiene series latex is a copolymer latex synthesized mainly by butadiene and acrylonitrile monomer, and has good adhesion, oil resistance, chemical resistance and wear resistance. After the introduction of unsaturated carboxylic acid, the stability and adhesiveness of the product are further strengthened. These characteristics lay a good foundation for the use of this kind of products in grease impregnated products and wear-resistant parts. Its disadvantages are low temperature resistance and ozone resistance is poor, slightly lower elasticity. Nitrile gloves have good tear resistance, puncture resistance, grease protection and basic chemical protection, and have high protection safety and more thoughtful protection for users. Neoprene latex Because of the polar chlorine group, the latex has good adhesion, high film strength, oil resistance, flame resistance, solvent resistance, heat resistance, ozone aging resistance and other properties; Disadvantages are cold resistance, poor insulation, storage stability is not as good as the first two.

 Liquid end hydroxyl polybutadiene rubber (HTPB) is a liquid rubber with hydroxyl functional group at the end of the molecular chain of polybutadiene, which is colorless or light yellow transparent liquid at room temperature. HTPB and chain extender, polyisocyanate cross-linking agent in the reaction at room temperature or high temperature can generate three-dimensional network structure of the solidified material, the solidified material has excellent mechanical properties, good transparency, especially has excellent hydrolysis resistance, acid and alkali resistance, wear resistance, low temperature resistance and excellent electrical insulation, good adhesion to non-polar and low polar materials, excellent air tightness. The moisture transmittance is very low. HTPB has a wide range of applications. For a long time, it is mainly used in the manufacture of adhesives for solid propellants. In recent years, it has been gradually promoted for the production of civil cast-type polyurethane elasteers, RIM polyurethane products and CASE polyurethane elastic materials. Due to the excellent electrical properties of HTPB, water resistance, corrosion resistance and dimensional stability, it is also used for the production of complex shape insulating materials by the casting method. The main application fields of HTPB include pouring tires, rubber and plastic floor, plastic runway and complex shaped rubber products, shoe materials, special foam plastics, special coatings, adhesives, potting materials, electrical insulating packaging materials, waterproof and anti-corrosion materials, underwater sealing materials, wear-resistant transport belt and other rubber modification and epoxy resin modification and other uses.
