The three-proof finishing agent for fabrics prepared by the invention has strong water-repellency and durability, and has a wide application temperature range.

Description

The preparation technology of three-proof finishing agent for fabric

Technical field

The present invention relates to the preparation technology of three-proof finishing agent for fabric.

Background technology

At present conventional fabric three-proof finishing agent to refuse water weather resistance not strong, temperature limit is little.

Summary of the invention

The object of the present invention is to provide the preparation technology of three-proof finishing agent for a kind of fabric, it is strong that its fabric of preparing is refused water weather resistance with three-proof finishing agent, and temperature limit is larger.

For achieving the above object, technical scheme of the present invention is the preparation technology of three-proof finishing agent for a kind of fabric of design, comprises the steps:

1) get 4-5 mass parts alkylphenol polyoxyethylene, 1-2 mass parts cetyl trimethylammonium bromide, 1-2 mass parts Zerol, 2-3 mass parts Trimethyllaurylammonium bromide, 6-7 mass parts glycidyl methacrylate, 6-9 mass parts stearyl methacrylate, 9-12 mass parts hydroxyethyl methylacrylate, 90-100 mass parts methacrylic acid perfluorinated nonene oxygen base ethyl ester, 12-32 mass parts acetone, 300-600 mass parts water and mix, form mixed solution;

2) pour homogeneous in clarifixator into after mixed solution is uniformly mixed, obtain oyster white pre-emulsion;

3) then at 47-48 ℃, in pre-emulsion, drip 3-4 mass parts azo two isobutyl imidazole hydrochlorides, 2-3 mass parts azo-bis-isobutyrate hydrochloride, 1-2 mass parts polypropylene glycol;

4) dropwise, the insulation reaction time is 13-14 hour, is then cooled to room temperature and filters, and obtains product.

Advantage of the present invention and beneficial effect are: the preparation technology of a kind of fabric with three-proof finishing agent is provided, its fabric of preparing can slow down the variation of the finishing composition surface orientation causing in water washing process greatly with three-proof finishing agent, wash 25 times, fabric water repellency can keep more than 75%, refuse water weather resistance strong, temperature limit is larger.
