Abstract

The present invention relates to water-thinned PVDC latex, and is especially a kind of water-thinned PVDC latex for painting special cloth and its preparation process. The water-thinned PVDC latex is prepared with mixed monomer through emulsion polymerization in the presence of emulsifier and initiator. The mixed monomer includes vinylidene chloride 75-90 %, acrylate monomer 8-20 % and unsaturated fatty acid 1-5 %. The water-thinned PVDC latex is used in treating non-woven fabric, and the treated non-woven fabric is hard, elastic, waterproof, heat resistant and crease resistant and may be used widely. In addition, the water-thinned PVDC latex has excellent compatibility with acrylic acid emulsion.

Description

technical field [0001] The invention relates to a water-based PVDC latex, in particular to a special water-based PVDC latex for coating on special cloth and a preparation method thereof. Background technique [0002] At present, in the treatment agent of non-woven fabrics, a single acrylic emulsion treatment agent is mainly used. This type of treatment agent has excellent adhesion, durability and softness. However, as the market changes, the requirements of users are also different. In the past, the treated non-woven fabric was required to be relatively soft, but now it is gradually turning to be relatively hard, full of good elasticity, and also has good water resistance and heat resistance. properties and wrinkle resistance. For example, it is mainly used for the treatment of tent cloth, the coating of the back of the carpet and the treatment of other non-woven fabrics. [0003] Chinese invention patent (publication number is CN1715559A) discloses a kind of latex for tis...
