Embodiment 1

[0065] The specific synthesis operation method is as follows:

[0066] 1. Preparation of vinyl terminated polyurethane emulsion

[0067] Put ethylene oxide diol polyether diol into the stainless steel reaction kettle, dehydrate in vacuum at 100-120 °C for 2 hours; then cool down to 80-90 °C, add toluene diisocyanate, and keep the reaction at 85-90 °C for 2 hours; At 70°C, the hydrophilic monomer dimethylolpropionic acid, the chain extender diethylene glycol, and β-hydroxypropyl methacrylate were added, and the reaction was incubated for 3 hours. During the reaction, acetone should be added if the viscosity is high. Cool to below 30°C, add neutralizing agent triethylamine, stir for 2-5 minutes, add water under high-speed stirring (1400 rpm-2500 rpm) to disperse into water emulsion, remove acetone in vacuum, prepare Outlet vinyl PU emulsion.

Abstract

This invention relates to a radiation polymerization method of river system polyurethane-siliceous acroleic acid lacquer cloth covering, characterized in that the action can be processed in normal temperature, and the speed can be controlled. The method comprises the following steps: a) preparing ethenyl polyurethane emulsion; b) preparing polyurethane-polyacrylacid ester emulsion; c) preparing polyurethane-siliceous acrylic ester emulsion using cobalt 60-ª† radiant. The coated fabric processed by said invention has water-proof function; in addition, it has water vapour permeability.

Description

technical field [0001] The invention relates to a preparation method of a water-based polyurethane-silicon-containing acrylic resin fabric coating adhesive. Background technique [0002] Fabric coating is the fastest and most widely developed finishing technology in recent years. The coated fabric has the effects of leather feeling, high resilience, plump and soft hand, and is waterproof, breathable, moisture-permeable, and anti-fouling. , flame retardant, antistatic and other special properties, occupy an important position in the three pillar products of textiles - clothing materials, industrial fabrics, and interior decoration. [0003] The textile industry is the pillar industry of my country's export and foreign exchange earning. After more than 20 years of development, my country has introduced and made nearly 1,000 sets of coating finishing production lines. The manufacturers and users of glue are mainly located in Jiangsu, Zhejiang, Shandong, Fujian and Shanghai and ...
