Embodiment 1

[0018] A method for making a high-foaming plastic insulation quilt for greenhouses. The material is made of the following ingredients in proportion by weight: polyethylene rice material 400, zinc oxide 8, AC foaming agent 30, tribasic lead sulfate 3 , DCP (dicumyl peroxide) 3, carbon black 25, stearic acid 15, calcium powder 350;

[0019] Its method of making is:

[0020] 1) Put the rice material into the hopper and stir evenly;

[0021] 2) Put other auxiliary materials into the internal mixer together with the evenly stirred rice materials, stir, and heat to a molten state;

[0022] 3) The melted material enters the 18-inch and 16-inch open mills to be thinned evenly and formed into pieces;

[0023] 4) Then enter the splicing machine, weigh, shape, and mold;

[0024] 5) Then enter the vulcanizing machine and foam for about 45 minutes;

[0025] 6) Mold opening, semi-finished products, edge trimming;

[0026] 7) Cut the slices in the slicer according to the required size; ...

Abstract

A high-foam EVA plastic quilt for the great insulating shed in order to increase the yield of the crops in the shed by 8-10% is proportionally prepared from polyethene particles, zinc oxide, foaming agent AC, tribasic lead sulfate, DCP (diisopropylbenzene peroxide), carbon black, stearic acid and calcium powder.

Description

technical field [0001] The invention relates to a kind of thermal insulation material for greenhouses, which can also be used for moisture insulation, sealing, buffering, thermal insulation and packaging materials in industries such as vehicles and ships, chemical industry, refrigeration, and architectural decoration; as well as residential houses, factory buildings, And the insulation layer of livestock and poultry houses. Background technique [0002] With the development of the national economy, the agricultural economy also plays a decisive role. Greenhouse operation is a very important item in agriculture, and has already had a considerable scale in agricultural production. Greenhouses allow people to eat fresh vegetables and fruits in off-seasons, making the crop market more abundant and creating considerable economic benefits for farmers. [0003] At present, the greenhouse insulation quilts commonly used by farmers are all made of paper, which can play a role in he...
