Problems solved by technology

[0003] At present, the application of FRP is constantly expanding. For example, FRP cable brackets and FRP cable bridges, especially open-air cable equipment, must not only avoid the erosion of the sun and rain, but also resist the thrust of strong winds. The single-type FRP has become more and more Difficult to meet complex and complex environmental requirements

Abstract

The invention belongs to the technical field of glass fiber reinforced plastics, and discloses reinforced glass fiber reinforced plastic and a compression molding process thereof. The reinforced glassfiber reinforced plastic comprises UP resin, PS synthetic glue, calcium carbonate stone powder, zinc stearate, a reinforcing agent, a microporous foaming agent and glass fibers. The compression molding process comprises the steps of S1 configuration, S2 modulation, S3 mold pressing and S4 finishing. The compression molding process has the following advantages and effects: a large number of micropore bubbles with small apertures are formed in the glass fiber reinforced plastic core, multiple physical characteristics such as the bending strength and bending elastic modulus of the glass fiber reinforced plastic are effectively enhanced; meanwhile, the reinforcing agent is added, so that a protective layer is formed on the surface of the glass fiber reinforced plastic, the weather resistanceof a glass fiber reinforced plastic component is greatly enhanced, and the weather resistance of a glass fiber reinforced plastic cable rack in the using process is greatly enhanced through combination of the reinforcing agent and the glass fiber reinforced plastic component.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic, and particularly relates to a reinforced glass fiber reinforced plastic and a molding process thereof. Background technique [0002] Fiberglass is a type of composite material. Because of its unique performance advantages, FRP materials have been widely used in more than ten industries related to aerospace, railways, decorative buildings, home furniture, advertising displays, craft gifts, building materials and bathrooms, yacht mooring, sports materials, sanitation projects, etc. It has been widely used and praised, and it has become the darling of the needs of new era merchants in the material industry. FRP products are also different from traditional material products, and are much better than traditional products in performance, use and life attributes. [0003] At present, the application of FRP is constantly expanding, such as FRP cable brackets and FRP cable trays, ...
