Abstract

The invention discloses an ultramicron three-proofing finishing agent and a preparation method thereof. The ultramicron three-proofing finishing agent is prepared in a way that 3 to 35 percent of perfluor hexyl acrylate, 2 to 45 percent of acrylate copolymer, 0.5 to 10 percent of N-methyl acrylamide, 0.1 to 5 percent of surfactant, 0.1 to 5 percent of V-50 initiating agent, 2 to 15 percent of acetic acid, 40 to 70 percent deionized water are selected as raw materials and are combined; and a blend range with better comprehensive performance and lower cost is provided so as to give full play to all the components. Through effective selection and proportional combination of the components, the three-proofing finishing agent provided by the invention is enabled to have the advantages of innocuity, harmlessness, good wash fastness, excellent air permeability, environmental friendliness, simple process, low cost and the like and perfectly meet market demands.

Description

technical field [0001] The invention relates to the technical field of waterproofing agents, in particular to an ultrafine particle three-proof finishing agent. Background technique [0002] In the world, waterproof finishing agents for textiles and clothing have been monopolized by large international companies, and they are controlled by foreign companies in terms of technology and raw materials, and they discriminate in technology and products. my country has always been a big country in textile, printing and dyeing, but in the field of fabric post-treatment, especially in the technology of water-repellent and oil-repellent finishing agents for fabrics, it has always been in a backward state. On the one hand, the patents and technologies are monopolized by large foreign companies, and on the other hand On the one hand, my country’s investment in research and development in this area is relatively insufficient, and the products sold in the market are all foreign product emu...
