Problems solved by technology

At present, domestic sizing agents for transparent boards generally use unsaturated polyester or PVAC emulsion alone. If unsaturated polyester emulsion is used alone, the fiber bundling and chopping properties cannot meet the processing requirements; if PVAC emulsion is used alone, the dispersibility and penetration speed The conflict cannot be resolved; at the same time, the refractive index difference between the film-forming agent and the matrix resin is large, which cannot meet the high transparency requirements
Existing sizing agents for transparent boards cannot solve the problems of dispersibility, penetration speed, antistatic performance and transparency at the same time

Abstract

The invention discloses a glass fiber soakage agent for producing transparent sheet yarns. The glass fiber soakage agent is prepared from 0.10 percent of silane coupling agent, namely vinyl triethoxy silane, 2.5 percent of film former, namely epoxy modified polyester resin emulsion, 0.04 percent of lubricant, namely polyethylene glycol non-ionic surfactant, 0.50 percent of antistatic agent, namely lithium chloride, 0.08 percent of pH regulator, namely glacial acetic acid and water. The transparent sheet yarns produced by the glass fiber soakage agent have the advantages of good dispersibility, high permeation speed, good short cut performance, no-static accumulation, good combination performance with matrix resin, ageing resistance, high light transmittance and stable quality, and the effective use ratio is greatly increased.

Description

technical field [0001] The invention relates to a glass fiber sizing for producing transparent board yarn. Background technique [0002] Fiberglass lighting panels are commonly known as glass fiber reinforced plastics, also known as transparent tiles. It is a lighting material used in conjunction with steel structures. It is mainly composed of high-performance film, reinforced polyester and glass fiber. The film plays a very good role in anti-ultraviolet and anti-static. The anti-ultraviolet is to protect FRP lighting. The polyester of the board does not yellow and age, and loses light transmission properties prematurely. Antistatic is to ensure that the dust on the surface is easily washed away by rain or blown away by the wind, so as to maintain a clean and beautiful surface. Due to its stable quality and durable features, it is widely used in roofs and walls of industrial, commercial and civil buildings. [0003] Glass fiber sizing is the key technology in FRP lighting...
