Abstract

The invention discloses a preparation process of an environment-friendly and energy-saving PP material. According to the technical scheme, the preparation process comprises the following steps: S1, preparing raw materials; step S2, mixing the raw materials, wherein the step S2 comprises the following steps: step 1, putting polypropylene resin into a mixing machine; 2, adding the pigment into the mixer for mixing, wherein the temperature range of the pigment adding is 60-65 DEG C; 3, adding an auxiliary agent into the mixing machine, and mixing at a low speed, wherein the adding temperature range of the auxiliary agent is 70-75 DEG C; 4, rotating and mixing the mixture in the mixer at a high speed until the temperature of the mixture is increased to 85-90 DEG C; 5, the mixture is put into a cold discharging barrel from the mixing machine to be cooled; 6, putting the mixture into a daily barrel for later use; step S3, gelling and mulling; s4, forming a film; step S5, stretching and embossing; step S6, tempering the diaphragm; step S7, cooling the diaphragm; and S8, the diaphragm is rolled.

Description

technical field [0001] The invention relates to the field of plastic manufacturing, in particular to a preparation process of an environment-friendly and energy-saving PP material. Background technique [0002] Polypropylene, abbreviated as PP, is a polymer obtained by polyaddition of propylene. It is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene itself has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties. It is precisely because polypropylene has good physical and chemical properties that polypropylene is used in machinery, automobiles, electronic appliances , construction, textile, packaging, agriculture, forestry, fishery and food industry and many other fields have been widely developed and applied, and according to the different fields of polypropylene use, enterprises also modified polypropylene materials according to the actual use requirem...
