Abstract

The invention discloses a manufacturing technique for EPE pearl wool. Jinpaomu serves as a raw material nucleating agent, a butane agent and monostearin serve as an accessory foaming agent and an anti-shrinking agent correspondingly, due to accessory matching, raw material foaming is sufficient, and accessories do not influence one another; raw materials are fed into the foaming agent for preheating treatment firstly, the preheating temperature is 50 DEG C, the preheated raw materials are subject to plasticizing heating, the plasticizing time can be shortened, and the problem of uneven melt density caused by uneven temperature during plasticizing heating can be solved; the mold opening temperature is 168 DEG C, the molding state of melt can be kept at the temperature, the amorphous form of the melt due to too high temperature can be prevented, and the condition that curing of the melt cannot be subject to traction due to too low temperature is avoided; after a sheet passes through a sizing drum, the width is 1.5 m through sizing, the width of the sheet is determined by the sizing drum, and the width facilities machining and treatment of the sheet in the later period; after the sheet is extended, burrs are removed, the step of removing the burrs is increased, and therefore the attractiveness of the sheet can be improved, and scrap edges can be removed.

Description

technical field [0001] The invention relates to the field of packaging material production, in particular to a production process of EPE pearl cotton. Background technique [0002] Polyethylene foamed cotton is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed, and poor in recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance. It is an ideal substitute for traditional packaging materials. Widely used in car cushions, pillows, electronic appliances, instruments, computers, audio, me...
