Embodiment Construction

[0029] With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, molded fiberglass grating of the present invention, take resin as base material, add appropriate accelerator, curing agent, take glass fiber yarn as reinforcing material and form through molding; The above-mentioned resin is one of ortho-phenylene resin, m-phenylene resin and vinyl resin. The appropriate amount of accelerator added means that the added weight group is: 0.5-3% cobalt isozincate with resin weight. In this embodiment, 2% cobalt isozincate with resin weight is added as accelerator. The appropriate amount of curing agent added means that the added weight group is: methyl ethyl ketone peroxide with a resin weight of 0.5-3%. In this embodiment, methyl ethyl ketone peroxide with a resin weight of 2% is added as a curing agent.

[0030] A method for producing the above-mentioned molded FRP grating, comprising the following steps:

[0031] ① Preheat the special lower mold a...

Abstract

The present invention relates to one kind of molded GRP grille and its production process, and features that the molded GRP grille is produced with resin as basic material, and through adding proper amount of promoter and curing agent and glass fiber as reinforcing material, molding and curing. The resin may be one of three kinds of resin, including vinyl resin, etc; the promoter is cobalt isozincate in 0.5-3 wt% of resin; and the curing agent is butanone peroxide in 0.5-3 wt% of resin. The molded GRP grille has high strength and easy edge trimming.

Description

technical field [0001] The invention relates to a fiberglass grating, in particular to a high-strength fiberglass grating and a production method thereof. Background technique [0002] After retrieving relevant patent documents, no molded fiberglass grating identical to the present invention and its production method have been retrieved at present. Due to the resin, glass fiber and production process of the existing FRP grating, the FRP grating produced can generally only be used as platforms, floors, trench covers and other places. For occasions with high strength requirements, such as high ship decks and high-rise buildings, it is difficult to meet their requirements, so it is necessary to develop FRP grating varieties with high strength and better performance to meet the needs of high-strength use occasions. Contents of the invention [0003] The object of the present invention is to provide a fiberglass grating that adopts molding and has high strength and can be used...
