Abstract

The invention relates to a method for preparing modified styrene-butadiene latex. The emulsion polymerization involved in the method needs to be carried out in the presence of an aqueous dispersion of inorganic nano-oxides with antibacterial and antifungal functions, and the method is carried out by pre-emulsification semi-continuous seed emulsion polymerization. conduct. The modified styrene-butadiene latex prepared by the present invention not only has excellent anti-mildew and anti-bacterial properties, but also has excellent anti-mildew properties when the recycled leather, cardboard and other products produced by it as an adhesive have excellent bonding strength. Antibacterial properties. Therefore, the present invention also relates to the modified styrene-butadiene latex prepared by the inventive method, and the use of the modified styrene-butadiene latex as a binder and the products produced by the modified styrene-butadiene latex as a binder, such as regenerated leather and / or cardboard.

Description

technical field [0001] The invention relates to a method for preparing modified styrene-butadiene latex. The modified styrene-butadiene latex is styrene-butadiene hybrid latex modified by inorganic nano oxide particles. The present invention also relates to the modified styrene-butadiene latex obtained by the method of the present invention and its application. The modified styrene-butadiene latex can be used as an adhesive in the production of products that are prone to mildew, such as recycled leather and cardboard. [0002] technical background [0003] Regenerated leather is a very versatile leather goods fabric today. It is made by crushing leather leftovers or regenerated leather raw materials into leather fibers of a certain size, and then mixing them evenly with natural rubber or synthetic latex, water and other raw materials, and pressing them into sheets of a certain thickness after demulsification. The final product obtained after drying, embossing and surface tr...
