Abstract

The invention discloses an organosilicon acrylate compound waterproof finishing agent emulsion. The organosilicon acrylate compound waterproof finishing agent emulsion is prepared from in percentage by mass: 52-68% of an organosilicon emulsion and 32-48% of a silicon-contained acrylate emulsion in a blending mode; the organosilicon emulsion is mainly prepared from vinyl nano SiO2 sol, polymerizable organosilicon monomers, and a vinyl siloxane emulsion in a polymerized mode; and the silicon-contained acrylate emulsion is mainly prepared from acrylate monomers and vinyl siloxane monomers in a polymerized mode through an emulsion. The acrylate emulsion has good film formation, adhesion and weather resistance, and has the compatibility with polar polymers and non-polar polymers, and the acrylate emulsion is in composition with the organosilicon emulsion, the defects that a single-composition organosilicon emulsion has poor film formation fastness and poor washing resistance on the surfacesof fabrics can be overcome. The emulsion can form the organosilicon film with low surface energy, can also change the surface roughness, and enhance the water repellency of the surface synergistically.

Description

technical field [0001] The invention relates to a waterproof finishing agent, in particular to a composite waterproof finishing agent of organosilicon and acrylate, belonging to the field of textile functional finishing agents. Background technique [0002] The technological progress of the textile industry and the development of chemical additives have improved the performance of textiles, especially their functionality. Fabrics with good water resistance are becoming more and more popular. [0003] The principle of textile waterproofing is to use a waterproof finishing agent to finish the textile, reduce the porosity of the fiber of the fabric, make it lower than the diameter of the water molecule, so as to prevent the water molecule from penetrating the fabric and form a good waterproof effect. [0004] Aluminum soaps and paraffin wax finishing agents were mostly used in the waterproof finishing of textiles in the early days, which formed deposited films on the surface o...
