Problems solved by technology

[0002] The traditional textile glass fiber sizing is mainly made of starch and paraffin. Before the compounding of glass fiber reinforced plastic products, this type of sizing needs to heat wash the glass fiber. Removing the sizing agent by heating and cleaning, resulting in complicated process, waste of materials, and unfavorable factors such as the need to deal with washing waste

Embodiment 1

[0047] The preparation method of reinforced textile glass fiber sizing agent:

[0048] A. Hydrolysis of silane coupling agent:

[0049] Add acetic acid to 500 grams of deionized water to adjust the pH value to 3-4, stir slowly at 300 rpm, add 3 grams of silane coupling agent, and continue stirring for 30-50 minutes. The stirring can be stopped when the solution is clear and free of oil droplets. And control the pH value to be less than 6 to make coupling agent hydrolyzate;

[0050] B. Dissolution preparation of solid antistatic agent:

[0051] After heating 100 grams of deionized water to 80°C, add 1 gram of solid antistatic agent, stir slowly until it is completely dissolved, and then cool to room temperature to prepare an antistatic agent solution;

[0052] C. Add the above-mentioned coupling agent hydrolyzate and antistatic agent solution into the configuration kettle, add 0.5 grams of lubricant, 80 grams of polyvinyl acetate emulsion, 20 grams of polyester emulsion, 50 g...

Embodiment 2

[0054] A. Hydrolysis of silane coupling agent:

[0055] Add acetic acid to 500 grams of deionized water to adjust the pH value to 3 to 4, stir slowly at 300 rpm, add 4 grams of silane coupling agent, and continue stirring for 30 to 50 minutes. The stirring can be stopped when the solution is clear and free of oil droplets. , and control the pH value to be less than 6 to make a coupling agent hydrolyzate;

[0056] B. Dissolution preparation of solid antistatic agent:

[0057] After heating 100 grams of deionized water to 80°C, add 2 grams of solid antistatic agent, stir slowly, and cool to room temperature until it is completely dissolved;

[0058]C. Add the coupling agent hydrolyzate and antistatic agent solution prepared above into the configuration kettle, add 0.4 grams of lubricant, 60 grams of polyvinyl acetate emulsion, 40 grams of polyester emulsion, and 40 grams of epoxy resin emulsion , 6 grams of polyurethane emulsion, 4 grams of surfactant and the remaining part of...

Abstract

The invention provides an impregnating compound for reinforced textile glass fibers, which takes novel organic polymer materials as a main body. The impregnating compound comprises the following compositions by weight percentage: 5 to 10 percent of polyvinyl acetate emulsion, 1 to 4 percent of polyester emulsion, 2 to 8 percent of epoxy resin, 0.2 to 2 percent of polyurethane emulsion, 0.01 to 0.2 percent of lubricant, 0.1 to 0.5 percent of coupling agent, 0.05 to 0.3 percent of antistatic agent, 0.2 to 3 percent of surfactant, 0.05 to 1 percent of acetic acid, and the balance being deionized water. The impregnating compound has good convergence, lubricity, film-forming property and antistatic property; the glass fibers which are treated by the impregnating compound have the characteristics of bending resistance, flexibility, tensile resistance, good solubility with resin and so on; and the impregnating compound is suitable for treating the surfaces of various reinforced textile glass fibers.

Description

technical field [0001] The present invention relates to reinforced textile glass fiber sizing agent and preparation method thereof, with novel organic macromolecule film-forming agent, including polyvinyl acetate emulsion, polyester emulsion, epoxy resin and polyurethane emulsion, coupling agent, lubricant as The main body has the advantages of flexibility, lubrication, bending resistance and tensile resistance, and is suitable for surface treatment of various textile fibers. Background technique [0002] The traditional textile glass fiber sizing is mainly made of starch and paraffin. Before the compounding of glass fiber reinforced plastic products, this type of sizing needs to heat wash the glass fiber. The use of heating and cleaning to remove the sizing agent leads to complex processes, waste of materials, and unfavorable factors such as the need to dispose of washing waste. In order to overcome the shortcomings of the traditional technology, it is necessary to develop...
