Problems solved by technology

[0005] Aiming at the problem that the existing sizing agent cannot effectively solve the contradiction among glass fiber dispersibility, hairiness, static electricity, soaking speed, and light transmittance, the present invention provides a glass fiber sizing agent for transparent boards. The glass fiber sizing agent produced by the sizing agent is The fiber yarn has the characteristics of good dispersibility, easy chopping, fast soaking speed, good compatibility with unsaturated polyester, high light transmittance of the produced board, and aging resistance.

Embodiment Construction

[0046] The technical scheme of the present invention will be further described below with specific examples, but protection scope of the present invention is not limited to this:

[0047] Referring to Table 1, in order to achieve high light transmittance, high production efficiency, and high yield requirements of the lighting board in these examples, we select homopolyvinyl acetate emulsion (referred to as emulsion binder A) that does not contain protective colloid for use and An epoxy modified unsaturated polyester emulsion (referred to as Emulsion Binder B) was mixed as a binder. The emulsion binder A is a homopolymer PVAc emulsion without protective colloid, and the particle size of the emulsion is between 0.3-3.0 microns, the acetone dissolution rate is 100%, the Tg is between 14-28° C., and the solid content is 45%. Emulsion binder B is an epoxy-modified unsaturated polyester emulsion, the particle size of the emulsion is between 0.3 and 1.0 microns, the acetone solubilit...

Abstract

The invention discloses a glass fiber impregnating agent for a transparent plate, which basically comprises the following components in percentage by weight: 0.15-1.0 percent of silane coupling agent, 3.0-20.0 percent of binding agent, 0.02-1.0 percent of lubricating agent, 0.05-0.8 percent of antistatic agent, 0.1-2 percent of pH value adjusting agent and the balance of deionized water, wherein the binding agent is epoxy-ester emulsion or a mixture of PVAc emulsion and the epoxy-ester emulsion, and the contents of the PVAc emulsion and the epoxy-ester emulsion are calculated by respective solid content. The invention adopting the epoxy-ester emulsion or the mixture of the PVAc emulsion and the epoxy-ester emulsion as the binding agent can improve the glass fiber impregnating speed and the production efficiency; in addition, the light refractive rates of the impregnating agent and matrix resin are close, and the transmittance of the produced plate is high.

Description

(1) Technical field [0001] The invention relates to a glass fiber sizing agent for transparent plates. (2) Background technology [0002] FRP lighting board, also known as glass fiber reinforced polyester lighting board, is composed of high-performance film, reinforced polyester and glass fiber. Due to its stable quality and durable features, the products can be widely used on roofs and walls of industrial / commercial / civil buildings, and can also be used for lighting in agricultural production. The service life of FRP lighting panels can reach 20 years. Generally, the lighting materials used in conjunction with steel structures have similar functions to commonly used glass. They are mainly used for roof lighting. They can have the same shape as corrugated steel plates and profiled steel plates. They are glass fiber reinforced. Plastic, has the characteristics of good crush resistance, easy cleaning, and convenient installation. The lighting light of the product is astigmati...
