[0046] The second aspect of the present invention provides the preparation method of the above-mentioned fluorine-free waterproof finishing agent, which comprises the following steps:

[0047] Take the above preparation raw materials according to the proportion, heat deionized water to 40-60°C, add emulsifier, stir for 15-30 minutes, then add modified acrylate copolymer under stirring state, stir and mix for 1 hour.

[0048] The third aspect of the present invention provides the application of the above-mentioned fluorine-free waterproof finishing agent in the field of waterproofing of textiles and paper.

Embodiment 1

[0051] Example 1 The invention provides a fluorine-free waterproof finishing agent, whose preparation raw materials include 35 parts of modified acrylate copolymers, 6 parts of emulsifiers, and 55 parts of deionized water in parts by weight.

[0052] The preparation method of described modified acrylate copolymer comprises the steps:

[0053] After drying the acrylate prepolymer to remove water, dissolve it in an appropriate amount of acetone, add it to the reactor, increase the temperature of the reactor to 65 degrees Celsius, and then add dropwise the acetone solution of dimethylglyoxime and isoflurane at the same time Ketone diisocyanate, reacted for 2 hours under stirring, cooled to room temperature, and obtained after discharging. Wherein the mass ratio of the acrylate prepolymer, dimethylglyoxime and isophorone diisocyanate is 5:0.6:1.2.

Abstract

The invention relates to the waterproof processing and finishing technology, and provides a fluorine-free waterproof processing finishing agent and an application thereof. The raw materials for preparing the fluorine-free waterproof processing finishing agent include 30 to 40 parts of modified acrylate copolymer, 3 to 12 parts of emulsifier, and 30 to 80 parts of deionized water by weight. The fluorine-free waterproof processing finishing agent does not contain PFOS (perfluorooctane sulfonic acid) and PFOA (perfluorooctanoic acid), is easy to biodegrade, has no biological accumulation, is small in harm to human bodies, and is a relatively safe and environmentally friendly product. In addition, the fluorine-free waterproof processing finishing agent of the invention effectively improves thestiffness, the water resistance and the long-term washability of textile fabrics.

Description

technical field [0001] The invention relates to waterproof finishing technology, a fluorine-free waterproof finishing agent and application thereof. Background technique [0002] Fabric finishing refers to all the processes of improving and improving the quality of fabrics except for scouring, bleaching, dyeing, and printing. The finishing content generally includes making the fabric width neat, stable in size and shape, improving the feel of the fabric, enhancing the appearance of the fabric, and flame-retardant and water-repellent. , oil repellency, sanitation, antistatic, easy decontamination and other finishing; according to the different places where the fabric is used, select the corresponding finishing content. For shower curtains used in bathrooms, the materials are mainly textile fabrics and plastic materials. Compared with plastic materials, textile fabrics have stronger aging resistance and tear resistance, so the service life of textile fabric shower curtains is ...
