Abstract

The invention discloses a self-crosslinking styrene-acrylic emulsion for non-woven fabrics and a preparation method of the self-crosslinking styrene-acrylic emulsion. The styrene-acrylic emulsion for the non-woven fabrics is prepared by using styrene and acrylate monomers as main monomers, and selecting a proper self-crosslinking monomer and a functional monomer to perform a self-continuous pre-emulsification seed emulsion polymerization process. According to the preparation method disclosed by the invention, the styrene-acrylic emulsion with excellent enhancement and fixation effects on non-woven materials is prepared by controlling the process conditions of emulsion polymerization, the types and proportions of the monomers, an emulsifier, an initiator, the self-crosslinking monomer and the functional monomer; moreover, the emulsion does not have volatilization of organic solvents in use, and is green and environment-friendly without VOC (volatile organic compound), so that the self-crosslinking styrene-acrylic emulsion has good commercial application prospects.

Description

[technical field] [0001] The invention relates to a self-crosslinking styrene-acrylic emulsion for non-woven fabrics and a preparation method thereof. [Background technique] [0002] Non-woven fabric (also known as "non-woven fabric" and "non-woven fabric") is a fabric formed without spinning and weaving. It first consists of a web structure composed of oriented or random fibers, and then mechanically and thermally bonded. It is a new generation of environmentally friendly materials reinforced by chemical or other methods. It has the characteristics of moisture-proof, breathable, flexible, low price, and recyclable, so it is widely used in medical and health (surgical gowns, protective clothing, masks, diapers, cosmetics, etc.) supplies, sanitary napkins, etc.), home decoration (wall coverings, tablecloths, bed sheets, bedspreads, etc.), clothing accessories (lining, fusible interlining, wadding, shaped cotton, etc.), industry (building substrates, reinforcement materials, p...
