Embodiment 1

[0026] 1) Mix and stir, mix the LDPE granules, nucleating agent and antistatic agent evenly in proportion, the base material occupies 65 parts of the total preparation materials, the nucleating agent occupies 8 parts of the total preparation materials, and the antistatic agent occupies the total preparation materials of 8 servings.

[0027] 2) Heating and melting, sending the uniformly mixed raw materials into the foaming machine at a pressure of 10 MPa, the raw materials are sent into the foaming machine, and firstly subjected to heat treatment at a heating temperature of 160° C., so that the raw material mixture melts to a liquid state at a constant temperature, The constant temperature is 175°C.

[0028] 3) Foaming, the medium-high temperature liquid raw material mixture in step 2) is foamed into a porous structure under the catalytic action of monoglyceride and butane agent, and the temperature of the raw material is lowered to 120°C in the molding heating section, and the...

Embodiment 2

[0034] 1) Mix and stir, mix the LDPE colloidal particles, nucleating agent and antistatic agent in proportion evenly, the base material occupies 67 parts of the total preparation materials, the nucleating agent occupies 9 parts of the total preparation materials, and the antistatic agent occupies the total preparation materials of 9 servings.

[0035] 2) Heating and melting, sending the uniformly mixed raw materials into the foaming machine at a pressure of 15 MPa, the raw materials are sent into the foaming machine, and firstly subjected to heat treatment, the heating temperature is 170°C, so that the raw material mixture is melted to a liquid state at a constant temperature, The constant temperature is 180°C.

[0036] 3) Foaming, the medium-high temperature liquid raw material mixture in step 2) is foamed into a porous structure under the catalytic action of monoglyceride and butane agent, and the temperature of the raw material is lowered to 140°C in the molding heating sec...

Abstract

The invention discloses a production process of EPE pearl cotton which comprises the following raw materials in parts by weight: 60-70 parts of a base material, 5-10 parts of a nucleating agent, 5-10parts of an antistatic agent, 10-20 parts of a foaming agent and 10-20 parts of an anti-shrinking agent; the base material is LDPE rubber particles, the nucleating agent is gold bubbles, the foaming agent is a butane agent, and the anti-shrinking agent is monoglyceride. According to the production process of the EPE pearl cotton, the base material, the nucleating agent, the antistatic agent, the foaming agent and the anti-shrinking agent are mixed and processed to obtain the EPE pearl cotton having the advantages of good pressure resistance and buffer performance, environmental protection, strong toughness, shock prevention, sound insulation, no deformation and good plasticity, wherein various raw materials are easy to get, the integrated production can be realized, and less pollution exists in the intermediate process; and the problems that the pressure resistance and buffer performance of conventional EPE pearl cotton produced by a general production process are bad, the produced EPEpearl cotton is easy to deform and bad in plasticity and energy saving and environmental protection effects of the production process are not obvious are solved.

Description

technical field [0001] The invention relates to the technical 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. Due to its special advantages, it not only does not pollute the environment, but also can be recycled repeatedly. Therefore, EPE pearl cotton foaming material is a new type of material that will never decline in the sun. With the advancement of time and the continuous development and application of products, EPE pearl cotton foaming materials will be more widely used in packaging and filling materials. At present, the production of EPE pearl cotton foaming materials has been relatively developed in the Pe...
