Problems solved by technology

[0003] With the widespread use of FRP, the quality requirements for its products are getting higher and higher. However, as a polymer material, it is flammable and there are many fire hazards in use.
At present, the main method to improve the flame retardancy of FRP products is to add flame retardants, but flame retardants have certain deficiencies, such as halogen-containing flame retardants, which have good flame retardant effects, but are prone to produce a large amount of harmful smoke during the flame retardant process. At the same time, when halogen-containing products are used outdoors under the condition of light, the anti-agi

Embodiment Construction

[0024] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments:

[0025] Embodiments of the present invention provide a method for producing flame-retardant high-strength FRP gratings, such as figure 1 shown, including the following steps:

[0026] Step 101, cleaning the mold.

[0027] Step 102, mixing unsaturated resin, expandable graphite, aluminum hydroxide, curing agent, and accelerator to prepare a flame retardant resin mixture. Among them, the mass ratio of unsaturated resin, expandable graphite, aluminum hydroxide, curing agent and accelerator is 100:10-30:5-15:1-2:2; the curing agent is methyl ethyl ketone peroxide and cyclohexane peroxide The ratio of the ketone mixture is 4:1; the accelerator is a cobalt accelerator.

[0028] Step 103, apply an appropriate amount of release agent on the mold.

[0029] Step 104, using the flame retardant resin mixture for molding: ...

Abstract

The invention discloses a production method of a flame-retardant high-strength fiberglass-reinforced-plastic grid. The production method comprises: mixing an unsaturated resin, expandable graphite, aluminium hydroxide, a curing agent and a promoter to prepare a flame-retardant resin mixed liquor; coating a mold lubricant on a mold; performing molding with the flame-retardant resin mixed liquor; performing heat-curing on the mold after molding; and cooling and demolding after curing to obtain a product. By using expandable graphite with excellent flame retardancy, the production method of the fiberglass-reinforced-plastic grid helps to reduce smog and harmful gases generated by combustion of the conventional fiberglass reinforced plastics, and improving flame retardation of the fiberglass reinforced plastic; by raising the processing temperature of the flame-retardant material, the production method helps to guarantee the original mechanical properties; and also the performances of heat insulation, anticorrosion and weatherability are improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic manufacturing, in particular to a production method of a flame-retardant high-strength glass fiber reinforced plastic grid. Background technique [0002] Molded glass fiber reinforced plastic (referred to as FRP) is a kind of sheet material with many regular spaces made of glass fiber as reinforcement material, unsaturated polyester resin as matrix, and compounded by manual winding and resin casting. . Because of its excellent corrosion resistance, flame retardant, light weight and high strength, impact resistance, insulation, non-slip, non-magnetic, beautiful, maintenance-free, easy installation, aging resistance, fatigue resistance and other characteristics, it is widely used in petrochemical, metallurgy, electric power , food, transportation, environmental protection and many other industrial fields. [0003] With the widespread use of FRP, the quality requirements for ...
