Problems solved by technology

[0003] At present, the glass steel plates used in the field of caravans, refrigerated cars, tanks, express logistics cars, and external walls of mobile houses limit their application due to their poor thermal insulation performance. It is necessary to improve the heat insulation of glass steel plates
The traditional heat-insulating FRP sheet processing method is to spray reflective paint on the surface of FRP sheet. Before spraying, the FRP surface needs to be polished, puttyed and repaired. The production process is cumbersome, complicated, high cost, low efficiency, and dust pollution. , but also prone to foaming, delamination, cracking and many other quality problems

Abstract

The invention discloses a heat-isolating glass fiber reinforced plastics panel and a preparation method thereof and belongs to the technical field of production of glass fiber reinforced plastics panels. The glass fiber reinforced plastics panel is coated with a gel coat. The gel coat is prepared from the following raw materials in parts by weight: 100 parts of unsaturated resin, 10-15 parts of flexible unsaturated resin, 15-20 parts of titanium dioxide, 10-20 parts of glass beads, 1-2 parts of a defoamer, 1-2 parts of a flatting agent, 0.3-1 part of an ultraviolet adsorbent, 0.2 part of an accelerant and 2-2.5 parts of a curing agent. The preparation process comprises the following steps of: spray-coating or blade-coating or roller-coating the gel coat to a glass fiber reinforced plastics base film; warming the film to be initially cured; spray-coating or blade-coating or roller-coating a matrix resin coating to the gel coat; then adding glass fibers to infiltrate, removing bubbles, adding a cover film, and defining thickness; and then warming and curing the film, and slitting and rolling the film. The obtained glass fiber reinforced plastics panel can reflect sunlit heat of 90% or above, is good in heat-isolating property, is prepared and formed at one time, and is stable in quality.

Description

technical field [0001] The invention relates to the technical field of glass steel plate production, in particular to a heat-insulating glass steel plate and a preparation process thereof. Background technique [0002] The scientific name of FRP is glass fiber reinforced plastic. It is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix material. Because its strength is equivalent to steel, and it contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, heat insulation and other properties as glass, so it is called "glass fiber reinforced plastic". With its unique strong corrosion resistance, smooth inner surface, low transportation energy consumption, long service life, convenient transportation and installation, no maintenance and low comprehensive cost, etc. It has been widely used in drainage, factory sewage treatment,...
