High-stability low-temperature-resistant plastic

Abstract

The invention relates to a high-stability low-temperature-resistant plastic which is prepared from the following raw materials in parts by weight: 2-4 parts of triethylenediamine, 3-6 parts of toluene diisocyanate, 2-5 parts of polyvinyl ester, 4-9 parts of epoxy resin, 18-25 parts of carbon black, 2-6 parts of phenolic resin, 4-7 parts of ethylene copolymer elastomer, 2-8 parts of closed-cell expanded perlite, 10-15 parts of PE (polyethylene), 4-9 parts of nylon, 1-3 parts of titanium white, 14-17 parts of tri-n-butyl amine, 3-7 parts of aluminum powder and 4-8 parts of graphite. The high-stability low-temperature-resistant plastic has higher mechanical properties and stability, can not become hard or brittle at low temperature, and can keep in normal state.

Description

technical field [0001] The invention relates to a low temperature resistant plastic with high stability. Background technique [0002] Plastics have played an indispensable role in China. China is a large agricultural country. Agricultural plastic products have become an indispensable material for the development of modern agriculture. Technical measures have been widely used in China's agriculture, forestry, animal husbandry, and fishery industries. However, with the widespread use of plastics, there are more and more problems. Although plastics can help crops resist the cold, plastics themselves also As the cold changes, studies have shown that the mechanical properties of plastics change significantly at low temperatures. As the temperature decreases, the strength increases, and the plasticity and toughness also decrease, which has a great impact on the instability of plastics. Therefore, there is a need for plastics in the market. The low temperature resistance is furth...
