Abstract

The invention discloses a waterproof reticular TPU composite film with good thermal insulation performance. The composite film comprises the following raw materials in parts by weight: 100-120 parts of thermoplastic polyurethane; 15-25 parts of chemical micro-beads; 10-20 parts of sepiolite powder; 10-20 parts of gelatin; 15-25 parts of expanded perlite; 10-20 parts of acrylic ester; 20-30 parts of one-component polyurethane; 5-10 parts of aluminum silicate; 10-30 parts of ceramic micro powder; 15-25 parts of perlite; 30-40 parts of an acrylic emulsion; and 20-30 parts of water. The heat preservation performance of the TPU composite film is greatly improved, so that the temperature inside the greenhouse is prevented from being influenced by the temperature outside the greenhouse, the temperature inside the greenhouse can be kept unchanged, the growth life of plants is greatly prolonged, and the death rate of the plants is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a waterproof net-shaped TPU composite film with good thermal insulation performance. Background technique [0002] Plastic greenhouse, commonly known as cold shed, is a simple and practical protective cultivation facility. Because of its easy construction, convenient use, and low investment, it is widely used by countries all over the world with the development of the plastics industry. Use bamboo, wood, steel and other materials, and cover with plastic film, to build an arched shed for the cultivation of vegetables, which can advance or delay the supply, increase the output per unit area, and help prevent natural disasters, especially in the early spring and late autumn off-season in the northern region. Serve fresh vegetables. [0003] The traditional shed film covering the plastic greenhouse usually adopts a single-layer plastic transparent film (for example, TPU fi...
