Abstract
The invention discloses a waterborne aromatic polyisocyanate cross-linking agent. The waterborne aromatic polyisocyanate cross-linking agent comprises the following components in percentages by mass:3 to 10% of fatty alcohol-polyoxyethylene ether, 10 to 20% of polyisocyanate, 3 to 15% of methylene succinic acid, 1 to 8% of polyether urethane, 1 to 5% of isophorone diamine, 2 to 10% of glycidyl methacrylate, 5 to 15% of acrylate, 3 to 10% of styrene, 0 to 8% of isopropanol and 1 to 5% of an auxiliary agent, with the balance being deionized water. The invention also discloses a preparation method for the above-mentioned waterborne aromatic polyisocyanate cross-linking agent. Compared with the prior art, the preparation method provided by the invention has the following advantages: the synthetic process is simple and standardized; the production process and production flow are easy to control; meanwhile, a product prepared by using the preparation method provided by the invention has reliable performance and good stability; production experience can be conveniently summarized and accumulated; production raw materials have good environmental protection performance; meanwhile, the waterborne aromatic polyisocyanate cross-linking agent provided by the invention effectively improves reaction efficiency of the raw materials and controlling and adjusting abilities to the reaction process, and has the characteristics of strong adhesion force, high peel strength, proper softness, good water resistance and scrubbing resistance and low film-forming temperature.
Description
technical field [0001] The invention belongs to the technical field of new materials, and particularly relates to a water-based aromatic polyisocyanate crosslinking agent and a preparation method thereof. Background technique [0002] Polyisocyanate crosslinking agent is a very frequently used raw material in the textile industry, which has an extremely important impact on the production, processing and performance of textiles. However, in actual use, it is found that the currently used polyisocyanate crosslinking agent The traditional formulas and processes that are often used in the agent can meet the needs of use to a certain extent, but its own toxicity is relatively large, and it is more harmful to the surrounding environment and users. At the same time, there are also insufficient adhesion and softness. , water resistance and low scrub resistance, so it cannot effectively meet the needs of actual use, and the product quality stability of related products is relatively ...
