Embodiment 1

[0024] Example 1: A method of manufacturing corrosion-resistant and flame-retardant FRP gratings through a pultrusion profile production system, the steps are as follows: evenly wind glass fiber filaments into a hollow cylinder, place the hollow cylinder on a rotating roller, The fiber filament rotating roller is placed on the creel on the yarn field for standby, and at the same time, the filament end of the glass fiber filament is pulled out to be put into the guide plate; the filament end is guided into the guide system, and the guide system includes the first guide plate 1, the second guide plate The guide plate 2 and the third guide plate 3, there is a transmission roller between the second guide plate 2 and the third guide plate 3, and the filament head is fixed through each guide plate and the transmission roller so that the glass fiber filament can be continuously transmitted to the impregnation equipment 4. The first guide plate 1, the second guide plate 2 and the third...

Embodiment 2

[0025] Example 2: Unsaturated polyester resin, flame retardant, anti-aging agent, curing agent, accelerator, and anti-falling agent are composed of a flame retardant resin mixture and injected into the impregnation device 4, and its mass ratio is 100:10:3:1 :2:0.5, the curing agent is a mixture of ketone peroxides, the accelerator is a cobalt accelerator, the anti-falling agent is silicon dioxide, and the anti-aging agent is a UV anti-aging agent; the heating and curing device 6 has a pressurizing function at the same time, The heating and curing temperature is 120°C, and the heating time is maintained for 1.5 hours. After curing, it is cooled and demolded.

Embodiment 3

Abstract

The invention discloses a method for manufacturing a corrosion-resistant and flame-retardant glass steel grid through a pultrusion profile production system. The method comprises the following steps: glass fiber filaments are leaded into a guide system; and unsaturated polyester resins, a flame retardant, an antiaging agent, a curing agent, an accelerant and a reduction inhibitor are formed to flame-retardant resin mixed liquid for filling in an impregnation device with the mass proportion of 100: 10-30: 3-5: 1-2: 2-3: 0.5-1.5, then enter a molding system for dipping, enter a heating curing device for curing, are cooled and demolded to enter a reciprocating traction device for towing, and enter a cutting device for cutting and finishing to obtain a product. The method can flexibly manufacture according to the production requirements, adopts a continuous production process to cut according to a specified dimension, and is high in production efficiency, stable, safe and reliable.

Description

technical field [0001] The invention relates to the field of composite material manufacturing, in particular to a method for manufacturing corrosion-resistant and flame-retardant FRP gratings through a pultrusion profile production system. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insul...
