preparation example Construction

[0026] Referring to the accompanying drawings, it can be seen that the preparation method of the fabric three-proof finishing agent of the present invention comprises the following reaction steps:

[0027] ① Mix the raw material monomers uniformly for later use, then weigh the compound emulsifier, and a mixed solvent composed of acetone and water, and mix the raw material monomers, compound emulsifier and mixed solvent evenly to form a mixed solution;

[0028] ② Stir the mixture and pour it into a homogenizer to homogenize to obtain a milky white pre-emulsion;

[0029] ③Then dripping an initiator solution with a concentration of 10% by weight in the pre-emulsion at 50-90°C;

[0030] ④ After the dropwise addition, the reaction time of heat preservation is 5-10 hours, then cooled to room temperature and filtered to obtain the product;

[0031] The raw material monomers are 50-80 parts by weight of perfluorononenyloxyethyl methacrylate, 15-40 parts by weight of stearyl methacryl...

Embodiment 1

[0041] Perfluorononenyloxyethyl methacrylate 65g, stearyl methacrylate 28g, hydroxyethyl methacrylate 3g and glycidyl methacrylate 4g are mixed for subsequent use, then take 1g of composite emulsifier ( The molar ratio of lauryltrimethylammonium bromide and alkylphenol polyoxyethylene ether is 1: 2), the mixed solvent that 5g acetone and 200g deionized water are formed, stirs and mixes evenly, after two kinds of mixtures are stirred and mixed Pour into a homogenizer and homogenize twice to obtain a milky white pre-emulsion, then pour the pre-emulsion into a four-necked flask equipped with an electric stirrer, a thermometer, and a condenser tube, heat up to 60°C, and add dropwise 5g of 10% Aqueous solution of dimethyl azobisisobutyrate. After the dropwise addition, keep the temperature at 60°C for 8 hours, cool and filter to obtain the product.

Abstract

The invention relates to a preparation method of a three-proofing fabric finishing agent, which comprises the following steps: (1) evenly mixing raw material monomers for later use, weighing a composite emulsifier and an acetone-water mixed solvent, and evenly mixing the raw material monomers with the composite emulsifier and the mixed solvent to form a mixed solution; (2) stirring the mixed solution, pouring the mixed solution into a homogenizer, and homogenizing to obtain a milk white preemulsion; (3) dropwisely adding a 10 wt% initiator solution into the preemulsion at 50-90 DEG C; and (4) after finishing the dropwise addition, reacting for 5-10 hours while keeping the temperature, cooling to room temperature, and filtering to obtain the product. In comprehensive consideration of raw material sources, functionality, convenience, economy and the like, the invention has the advantages of simple synthesis, low price, low krafft point, wide temperature limit and the like. The invention also discloses a three-proofing fabric finishing agent produced according to the preparation method.

Description

technical field [0001] The invention relates to a preparation method of a three-proof finishing agent for fabrics, and also relates to a three-proof finishing agent for fabrics prepared according to the preparation method. This fabric three-proof finishing agent does not contain perfluorooctane sulfonyl compounds (PFOS) which are harmful to the environment. Background technique [0002] Fabric three-proof finishing agent, "three-proof" refers to water-repellent, oil-repellent, and stain-repellent finishing. It is to apply one or several finishing agents on the fabric to change the surface properties of the fabric, so that the fabric is not easily wetted by water and common oil stains. wet or dirty. Its uses include high-end women's and men's outerwear, windbreakers, jackets, casual wear, hook clothing, etc., various protective clothing such as oil field overalls, mine overalls, fire protection clothing (composited with flame-retardant finishing) and special military uniform...
