Embodiment Construction

[0014] 1. Production of straw composite foam shoe material raw materials:

[0015] Crush the natural straw to 600-800 mesh.

[0016] The crushed natural straw, polyethylene, calcium carbonate and plastic additives are mixed evenly in proportions of 25-30%, 20-24%, 41%-53% and 2-5% of the total mass of raw materials respectively, and then densely Refining and tabletting become the raw material sheet of the present invention.

[0017] 2. Forming

[0018] Calculate the weight required for foaming according to the size of the mold, accurately weigh the straw composite foam shoe material raw material sheet in step 1, and place it in the mold of a multi-layer molding press for high-temperature vulcanization and foaming. The foaming temperature is 150-170°C and the foaming time is 5-7 minutes, then the straw composite foamed shoe material of the present invention can be obtained.

[0019] 3. Application

[0020] The straw composite foamed shoe material described in step 2 can be ...

Abstract

The invention discloses a straw compound foamed shoe material and a production processing method thereof, and relates to the technical field of plastic raw materials and products. After natural straw, low-density polyethylene, calcium carbonate and plastic aid are mixed, the mixed materials are placed in a compression roller and sheeted, and raw material sheets of the straw compound foamed shoe material can be obtained. The raw material sheets can be directly shaped; and after the raw material sheets of the straw compound foamed shoe material are heated, shaped products of different shapes can be obtained by closed vulcanization foaming of a die press. The heat setting temperature of the straw compound foamed shoe material is much lower than that of the conventional non-degradable plastic, the production energy is saved, the equipment and the environment are protected, the disintegration period of the shoe material under the conditions of strong sunlight and severe temperature difference is 180 days, and the disintegration period of a compost is 120 days.

Description

technical field [0001] The invention relates to the technical field of plastic raw materials and products. Background technique [0002] With the great development of the plastics industry and a large number of applications of plastics, the problem of waste plastics is becoming more and more serious. Traditional plastics cannot be naturally degraded after being discarded and cause serious pollution to soil, groundwater and air. Direct recycling is half the effort and inefficient. The resulting white pollution has become a global problem, and the pressure on environmental protection is extremely huge. Shoe materials are one of the main uses of plastics. Adding straw and other natural organic matter to shoe materials can reduce the use of non-degradable plastics and slow down the oil crisis. Contents of the invention [0003] The purpose of the present invention is to invent a straw composite foam shoe material to reduce the use of non-degradable plastics and slow down the...
