preparation example Construction

[0015] A method for preparing light-transmitting variable flame-retardant glass fiber reinforced plastics, comprising the following steps:

[0016] 1. Preparation of light-transmitting flame-retardant glass layer:

[0017] It is made of transparent resin and glass fiber, and added with flame retardant materials.

[0018] 2. Preparation of the light-transmitting variable layer mixture: one of the transparent resins such as unsaturated polyester resin, epoxy vinyl resin and other transparent resins, photochromic glass powder, initiator, accelerator, according to the ratio requirements, first Mix the photochromic glass powder evenly in the transparent resin, then add the initiator and stir evenly, finally add the accelerator and mix evenly, set aside.

[0019] 3. Preparation of the light-transmitting variable layer: apply the mixture of the light-transmitting variable layer prepared in step 2 on the surface of the light-transmitting FRP in step 1 and cure it.

Abstract

The invention relates to fiberglass reinforced plastic, in particular to transparent variable flame retardant fiberglass reinforced plastic. The transparent variable flame retardant fiberglass reinforced plastic comprises a transparent flame retardant glass plate layer containing fiber glass and a transparent variable layer. The transparent variable layer is prepared with substance comprising copal gum, photochromic glass micropowder and an initiator according to 100:20-90:1-5 by weight. The preparation method of the transparent variable flame retardant fiberglass reinforced plastic comprises the following steps: the transparent flame retardant glass plate layer is prepared; the mixture of the transparent variable layer is prepared; and the transparent variable layer is prepared. As the technical solution is adopted, the illumination problem in buildings is solved so that the light intensity in the buildings can change with the illumination, thus meeting the requirement of illumination, improving the safety of the buildings and producing great economic benefits.

Description

technical field [0001] The invention relates to glass steel, in particular to a glass steel with variable light transmission and flame retardancy. Background technique [0002] Light-transmitting FRP is a glass fiber reinforced resin composite lighting material. It has the characteristics of high strength, non-fragility, good toughness, and easy molding. Therefore, it is widely used in the construction of transparent squares, transparent workshops, transparent greenhouses, etc., with significant economic benefits. However, the usual light-transmitting FRP can only transmit light, and cannot adjust the light transmittance with the change of light intensity. Ordinary light-transmitting FRP has no flame-retardant effect. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant light-transmitting FRP that can adjust the light transmittance as the light intensity changes. [0004] The technical solution to achieve the object of th...
