Problems solved by technology

Since the winding process of polyurethane is more complicated than that of polyester and epoxy resin, its use tension is high, and it is also very sensitive to ambient temperature and humidity. In the process, glass fibers are also required to have less hairiness and low water content. , small migration of combustible content, fast soaking speed, etc., but the glass fiber in the existing market has been difficult to meet its requirements

preparation example Construction

[0045] The preparation method of the embodiment of the present invention and comparative example 1 comprises the following steps:

[0046] 1) Weigh 40-50% of the total water mass into the preparation container, then slowly add the silane coupling agent, and continue stirring for 25-30 minutes;

[0047] 2) Weigh water 3-10 times the mass of the lubricant and heat it to 50-60°C, then add the lubricant into the water at 50-60°C, stir thoroughly to prepare a lubricant solution, and then add it to the preparation container;

[0048] 3) Add film-forming agent A to water whose mass is 2 to 3 times the mass of film-forming agent A, and fully stir to prepare film-forming agent A emulsion; add film-forming agent B to water whose mass is 2-3 times the mass of film-forming agent B times the amount of water, fully stirred to prepare film-forming agent B emulsion; film-forming agent A emulsion and film-forming agent B emulsion were added to the preparation container;

[0049] 4) Add the re...

Abstract

The invention discloses a glass fiber sizing and its preparation method and application. The glass fiber sizing contains solid components and water; the mass of the solid components accounts for 3-8% of the total mass of the sizing; the solid components contain the following components , the ratio of the mass of each component to the total mass of the solid component is as follows: silane coupling agent 3-10%, lubricant 1-10%, film-forming agent A 20-70%, film-forming agent B 20-70%, Film-forming agent A+film-forming agent B 80-96%; wherein, the silane coupling agent is an amino-containing silane coupling agent, and the film-forming agent A and film-forming agent B are polyurethanes with different relative molecular weights. The glass fiber products produced by using this sizing agent can meet the requirement of less hairiness under high tension in the polyurethane winding process, have good compatibility with the polyurethane matrix resin, fast soaking speed, and high mechanical properties of the subsequent products.

Description

technical field [0001] The invention belongs to the field of glass fiber sizing agents, and in particular relates to a glass fiber sizing agent for strengthening polyurethane resin winding process, its preparation method and application, and involves a glass fiber thermosetting resin technology. Background technique [0002] Polyurethane composite material has the characteristics of light weight, high strength, good toughness, corrosion resistance, excellent electrical insulation, designable performance, and maintenance-free. It is an ideal choice for pole structural materials. It has begun and is increasingly receiving high attention from domestic and foreign power industries. . Compared with traditional poles (cement poles and steel pipe towers), polyurethane composite poles have the characteristics of light weight, high strength, aging resistance, and excellent toughness. Therefore, in foreign countries, the application of polyurethane poles has already reached a conside...
