s1, taking a filler according to parts by weight, crushing, and sieving with a 250-300-mesh sieve to obtain filler powder;
s2, adding the rest raw materials into the filler powder, uniformly mixing in a mixer, heating and frying for 20-30 min at the temperature of 120-150 ℃, and making into slurry in a molten state;
s3, introducing the slurry into a granulator, continuously heating to 200-300 ℃, extruding a block through a grinding head, and crushing to obtain high-temperature-resistant plastic particles for later use;
s4, directly placing the prepared high-temperature-resistant plastic particles in a mold cavity, closing the mold, heating and pressurizing, liquefying the plastic, carrying out chemical reaction to solidify the plastic, and opening the mold after cooling.
The embodiment method can manufacture plastic products with various shapes according to the shapes of the molds.
In conclusion, the high-temperature resistant plastic product can still maintain high mechanical property under the high-temperature condition, has high strength and stable size, and has no deformation and color change phenomenon after being placed at the temperature of 80 ℃, 90 ℃ and 100 ℃ for 24 hours.
