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, vacuum dehydration at 100-120℃ for 2h; then lower the temperature to 80-90℃, add toluene diisocyanate, and react at 85-90℃ for 2h; cooling down At 70°C, the hydrophilic monomer dimethylolpropionic acid, the chain extender diethylene glycol, and β-hydroxypropyl methacrylate were added, and the reaction was kept for 3 hours. During the reaction, acetone should be added if the viscosity is high. Cool down to below 30℃, add neutralizer triethylamine, stir for 2-5 minutes, add water under high-speed stirring (1400 rpm-2500 rpm) to disperse into an aqueous emulsion, remove acetone by vacuum, prepare Export vinyl PU emulsion.

[0068] The dosage of each component in the above process is as follows:

[0069] Polyoxyethylene ether glycol 100g

[0070] Toluene diisocyanate 40-...

Embodiment 2

[0091] The specific synthesis operation method is as follows:

[0092] 1. Preparation of vinyl-terminated polyurethane 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-gamma 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 water-based polyurethane-silicon-containing acrylic resin fabric coating glue. Background technique [0002] Fabric coating is the fastest growing and most extensive finishing technology in recent years. The coated fabric has the effects of leather feeling, high resilience, plump and soft hand feeling, and it is waterproof, breathable, moisture permeable, and antifouling. , 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 a pillar industry for my country’s export earnings. After more than 20 years of development, my country has introduced and self-made nearly a thousand sets of coating finishing production lines. The annual output of domestic coating glue has reached 150,000 tons. Glue manufacturers and users are mainly located in Jian...
