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
The present invention relates to a kind of water-based PVDC latex, relate in particular to a kind of water PVDC latex specially for painting special cloth and preparation method thereof.
Background technology
Aspect the treatment agent of non-woven fabrics, mainly be the treatment agent that adopts single ACRYLIC EMULSION type at present, such treatment agent has good cementability, weather resistance and softness.But along with the variation in market, user's requirement also has nothing in common with each other, and the non-woven fabrics after the past require to handle is soft, and turns to harderly now gradually, and rich elasticity preferably also has water tolerance, thermotolerance and wrinkle resistance preferably simultaneously.As processing and the coating at the carpet back side and the processing of other non-woven fabrics that is mainly used in tent cloth now.
Chinese invention patent (publication number is CN1715559A) discloses a kind of latex for coating drinking filter bag cotton paper and preparation method thereof, it forms by emulsion polymerization way copolymerization in the presence of emulsifying agent, initiator, the mix monomer component of latex is: (1) vinylidene chloride, consumption are the 60-85% of mix monomer total amount; (2) acrylic ester monomer, consumption are the 5-30% of mix monomer total amount; (3) unsaturated fatty acids, consumption are the 5-10% of mix monomer total amount.This invention has: the tissue paper of coating is had than high wet strength, and the infiltration water ability is strong, characteristics such as few and cost performance height of nonpoisonous and tasteless, leachable thing, and the utmost point is applicable to bag for extracting beverage tissue paper surface coated such as coffee, tealeaves.But it can't satisfy the requirement that non-woven fabrics is handled owing to have higher water absorbability after the emulsion drying.
Summary of the invention
In order to address the deficiencies of the prior art, an object of the present invention is to provide and a kind ofly make the non-woven fabrics after the processing harder, rich elasticity preferably also has the water-based PVDC latex of water tolerance, thermotolerance and wrinkle resistance preferably simultaneously.
