Title:
HEAT RESISTANT NEOPRENE LATEX ADHESIVE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/095495
Kind Code:
A1
Abstract:
A heat resistant neoprene latex adhesive and a preparation method therefor, the heat resistant neoprene latex adhesive comprises the following components in parts by weight: 30-60 parts of a modified heat resistant neoprene latex, 30-60 parts of a neoprene latex, 100 parts of a styrene-acrylic emulsion (SAE)), 5-15 parts of a tackifying emulsion, 0.2-0.6 part of an aqueous metal oxide solution, 0.2-0.6 part of an aqueous anti-aging agent solution, 0.3-0.8 part of a thickening agent and 1-3 parts of a coagulant, wherein the styrene-acrylic emulsion is a general raw material, and the solid content is 40-50%. Both methyl methacrylate and octavinyl-POSS monomers are grafted on the neoprene latex by means of an emulsion polymerization method, such that the heat resistance and storage stability of the neoprene latex adhesive prepared from the modified neoprene latex are improved.
