Embodiment 1
[0012] Example 1: Take by weight: 50 parts of magnesium chloride, pulverized and mixed with 30-50 parts of water, 10 parts of dilute sulfuric acid with a concentration of 10% by weight, 100 parts of light magnesium oxide and 1.0 parts of zinc stearate, pulverized to less than 180 μm, talc 30 parts of powder, 0.75-1.5 parts of cellulose, 2 parts of urea-formaldehyde resin, 0.3 part of resin, 0.5 parts of methyl ethyl ketone peroxide, 0.2 parts of oxalic acid, 1.5 parts of waterproof powder, and mix the above materials evenly to obtain a slurry mixture.
[0013] Take the glass fiber cloth and lay it in the mold, and evenly brush the above slurry mixture on the glass fiber braid, the thickness of the brushing is controlled at 3-5mm, and then spread the glass fiber braid layer on the slurry mixture, repeat this process for 3 Second, a layered composite member consisting of 4 layers of fiberglass braids with a paste-like mixture in between.
Embodiment 2
[0014] Example 2: Take by weight: 40 parts of magnesium chloride, pulverized and mixed with 40 parts of water, take fuming concentrated sulfuric acid and dilute it into dilute sulfuric acid with a concentration of 12% by weight, then take 8 parts of prepared dilute sulfuric acid, light magnesium oxide 100 and 0.7 parts of zinc stearate, all crushed to less than 150 μm, 20 parts of talcum powder, 0.75 parts of cellulose, 1.5 parts of urea-formaldehyde resin, 0.6 parts of resin, 0.5 parts of methyl ethyl ketone peroxide, 0.25 parts of oxalic acid, 2 parts of waterproof powder , Mix the above raw materials evenly to obtain a slurry mixture.
[0015] Lay a layer of glass fiber cloth in the mold, and evenly brush the above-mentioned slurry mixture on the glass fiber braid, the thickness of the brushing is controlled at 3-5mm, and then spread the glass fiber cloth on the slurry mixture, and repeat the operation for 5 Second, a layered composite member consisting of 6 layers of fib...
Embodiment 3
[0016] Example 3: Take by weight: 45 parts of magnesium chloride, pulverized and mixed with 40 parts of water, 10 parts of dilute sulfuric acid with a concentration of 7% by weight, 90 parts of light magnesium oxide and 0.8 part of zinc stearate, all pulverized to less than 75 μm, talcum powder 40 parts, 1 part of cellulose, 1.8 parts of urea-formaldehyde resin, 0.4 parts of resin, 0.46 parts of methyl ethyl ketone peroxide, 0.25 parts of oxalic acid, 1.5 parts of waterproof powder, and mix the above materials evenly to obtain a slurry mixture.
[0017] Take the glass fiber cloth and lay it in the mold, and evenly brush the above-mentioned slurry mixture on the glass fiber braid, the thickness of the brushing is controlled at 4-6mm, and then spread the glass fiber braid layer on the slurry mixture, and so on. 2 times to form a layered composite member consisting of 3 layers of glass fiber braids and a paste-like mixture between them.
