Embodiment

[0036] Formula: Kaolin (1250 mesh) 70%, stearic acid 3%, polyethylene wax 14%, LDPE (melt index 7) 10%, ethylene-acrylic acid copolymer 3%.

[0037] First put the kaolin and stearic acid into the high-speed mixer, and mix at high speed for 15 minutes to complete the first step of powder treatment. Then put all the materials into the high-speed mixer and mix at high speed until the polyethylene wax melts and coats the powder. Then put the pre-modified material into the twin-screw granulation unit for granulation to complete the granulation.

[0038] We added this masterbatch into polypropylene F401, the masterbatch addition amount was 20% (parts by weight), the measured performance:

Abstract

The technical essentials of an insulation and warming masterbatch for a plastic greenhouse membrane provided by the invention are as below: 1, a kaolin powder processing technology: the kinetic energy of fins of a high-speed mixer breaks agglomerated particles of a superfine powder, and stearic acid mixed with the powder melts with the friction heat of powder to a molten state, and then coats the powder; 2, pre-modified material manufacturing technology: a formula comprises 70% of kaolin (1250 mesh), 3% of stearic acid, 14% of polyethylene wax, 10% of an LDPE1F7B (melt index of 7) and 3% of an ethylene acrylic acid copolymer; kaolin and stearic acid are added into the high-speed mixer and subjected to high speed mixing for 15 min to complete the first step of powder treatment; and then all the ingredients are added into the high-speed mixer and subjected to high speed mixing until the process released heat melts the polyethylene wax and coats the powder, so as to complete the pre-modified material manufacturing technology; and 3, kaolin masterbatch manufacturing: mechanical heating and granulation by using a twin screw granulator are carried out; and hot cutting granulation and stay water-cooling granulation are both applicable.

Description

technical field [0001] The invention relates to a superfine kaolin masterbatch for heat preservation and temperature increase of a plastic greenhouse film which has a blocking effect on infrared rays. Background technique [0002] At present, the production of vegetables, fruits, and flowers in plastic greenhouses is developing rapidly in my country. The Chaoyang area has become the base of greenhouse vegetables in my country. The production of greenhouses in Liaoning Province is also developing rapidly. All provinces are developing greenhouse production, increasing farmers’ income and enriching social vegetables. substance. The primary problem in managing the production of plastic greenhouses is to keep warm in winter, so that the temperature inside the shed is much higher than that outside the shed, so that the crops can germinate, grow, and mature. Even in the cold winter season, the crops in the shed can still grow. In order to maintain the temperature in the greenhouse,...
