Embodiment 1
[0029] A washing machine cover based on strong sealing and explosion-proof performance, including a cover body and cover glass, the cover glass is made of high borosilicate glass, and the material of the cover body is made of colorant, color masterbatch and engineering modified plastics. Engineering modified plastics are composed of short glass fiber reinforced PP materials, high-gloss and high-weather-resistant PP materials, and high-impact, environmentally friendly and flame-retardant ABS materials;
[0030] The coloring material adopts WN-144 gray black 710H colored ABS material, and the engineering modified plastic adopts electromagnetic heating process.
[0031] The raw material ratio of the machine cover body is: 6% of coloring material, 12% of color masterbatch, and 82% of engineering modified plastic.
Embodiment 2
[0033] The preparation method of the cover glass is as follows:
[0034] The first step: material selection: select a high borosilicate glass plate with a flat surface and no trachoma;
[0035] The second step: cutting: cutting the high borosilicate glass into a circle with a diameter of 40cm;
[0036] The third step: hot pressing forming: preheat the high borosilicate glass, the preheating temperature is 300-450 ℃, and then carry out hot stamping, hot pressing the high borosilicate glass into a concave shape, the hot pressing temperature is 800-1060°C, hot-press setting time is 30min;
[0037] Step 4: Grinding: After the high borosilicate glass is hot-pressed and formed, it is cooled, and the edge of the high borosilicate glass is polished with a grinder to remove burrs.
[0038] In the process of high borosilicate glass processing, borosilicate glass is added with boron water glass sand, soda water and ground lime, which are the glazes made by traditional glass, and then f...
Embodiment 3
[0041] A washing machine cover based on strong sealing and explosion-proof performance and a preparation method thereof, the preparation method of the cover body is as follows:
[0042] Step 1: Weighing: Weigh 600g of colorant, 1200g of color masterbatch and 8200g of engineering modified plastic according to the ratio of 6% of colorant, 12% of color masterbatch and 82% of engineering modified plastic;
[0043] The second step: mixing: uniformly mix 600g of colorant, 1200g of color masterbatch and 8200g of engineering modified plastic;
[0044] The third step: heat injection molding: the mixed engineering modified plastics are heated and injected to make the main body of the machine cover.
[0045] Short glass fiber reinforced PP material has high rigidity and high specific strength, low thermal expansion coefficient, good wear resistance and good creep resistance;
[0046] ABS is a styrenic plastic formed by the copolymerization of acrylonitrile, butadiene and styrene; among ...
