Problems solved by technology

Usually, FRP grating is molded by immersing glass fibers in a resin mixture solution, but the heated mixture solution will inevitably volatilize, especially in summer, the volatilized gas of the mixture solution will more or less cause harm to the human body

Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment:

[0024] Experimental raw materials:

[0025] 90-100 parts of epoxy resin;

[0026] 30-40 parts of epoxy resin modifier;

[0027] 80-90 parts of room temperature curing agent;

[0028] 5-10 parts of pigment;

[0029] 1-5 parts of release agent.

[0030] Test method: Stir and mix the above materials into the mold, take it out after 40 minutes.

[0031] Heat resistance test: Place the sample in a baking oven, set the temperature at 50°C and 100°C, and bake for 30 minutes respectively.

[0032] Acid resistance test: Place the sample in sulfuric acid for 30 minutes.

[0033] Alkali resistance test: place the sample in sodium hydroxide for 30 minutes.

[0034] Impact resistance test: A 50Kg discus falls freely and impacts downward to observe whether the surface is broken or deformed.

[0035] The experimental data are shown in the table below:

Abstract

The invention discloses normal-temperature impregnating resin for fiber reinforced plastic grids. The normal-temperature impregnating resin for the fiber reinforced plastic grids is composed of, by weight, 90-100 parts of epoxy resin, 30-40 parts of epoxy resin modifying agent, 80-90 parts of normal-temperature curing agent, 5-10 parts of pigment and 1-5 parts of release agent. The normal-temperature impregnating resin for the fiber reinforced plastic grids has the advantages of being needless of heating, easy to process, low in toxicity, high in solidifying speed, resistant to corrosion and high temperatures, capable of achieving demolding easily, high in reliability, low in cost and the like.

Description

technical field [0001] The invention relates to a normal-temperature impregnating resin for a glass fiber reinforced plastic grid. Background technique [0002] FRP grating is a reinforced material that uses glass fiber as a matrix and is plasticized by resin. FRP gratings are more and more widely used, so the production and performance of FRP gratings are getting higher and higher. Usually, FRP grating is molded by immersing glass fibers in a resin mixture solution and heating, but the heated mixture solution will inevitably volatilize, especially in summer, the gas volatilized from the mixture solution will more or less cause harm to the human body. Therefore, in practical applications, it is more desirable to reduce the molding temperature of FRP grating to room temperature without affecting the corrosion resistance and heat resistance. Contents of the invention [0003] The purpose of the present invention is to provide a fiberglass grating room temperature impre...
