Abstract

The invention relates to an antifreeze agent, an environmental protection antifreeze tube and a preparation method and application thereof. The antifreeze is composed of the following components in parts by mass: 4-7 parts of polydimethylsiloxane elastomer; 1-3 parts of polyoxyethylene propylene ether; 3-(2,3-glycidoxyl ) 2 to 4 parts of propyltrimethoxysilane. The antifreeze agent provided by the invention has the advantages of high molecular weight, excellent cold resistance effect, flame resistance, non-toxicity and environmental protection. Frost performance, enhanced low temperature toughness and impact resistance, good stability, is a cost-effective product. The environmental protection antifreeze pipe provided by the invention has excellent frost resistance, can effectively prevent pipe bursting, is suitable for transportation and construction in winter, can be safely used in the field of water supply transportation, and opens up a new road for antifreeze for domestic waterways.

Description

technical field [0001] The invention belongs to the field of pipe materials, and more specifically relates to an antifreeze agent, an environment-friendly antifreeze pipe and a preparation method and application thereof. Background technique [0002] Low temperature has a great influence on the mechanical properties of plastics. It is not uncommon for tubes to burst in winter when the temperature is low, which brings certain difficulties and quality risks to transportation and installation. How to improve the antifreeze performance of pipes has been perplexing the majority of production enterprises. According to the analysis of this problem, it can be seen that there are two main reasons for pipe bursting: one is that the weather is too cold in winter. If the intermolecular repulsion becomes larger, that is, the principle of cold shrinkage, when the intermolecular repulsion is greater than the cohesion of the molecular structure, it may cause the molecular structure to be d...
