Problems solved by technology

[0003] At present, rubber floor mats are made of polyurethane adhesive mixed with rubber granules, which are mostly pressed at high temperature. Generally, the mold temperature is 120-160°C, and the heating device needs to be turned on continuously, which consumes a lot of energy. It is used for rubber floor mats. Most of the particles are rubber particles or EPDM particles. After high temperature vulcanization, it will produce pungent smell and smoke, which will cause serious impact and damage to the environment and human body. Generally speaking, it is not energy-saving and environmentally friendly.

Abstract

The invention relates to the technical field of polyurethane adhesives, and in particular, relates to a low-temperature rapidly-vulcanized polyurethane high-temperature adhesive as well as a preparation method and application thereof. The low-temperature rapidly-vulcanized polyurethane high-temperature adhesive comprises the following raw materials in percentage by mass: 35-45% of polyether polyol, 35-40% of isocyanate, 3-6% of a coupling agent, 10-15% of a plasticizer, 1-1.5% of an antioxidant, 2.5-8% of an ultraviolet light absorber and 0.5-1% of a compound catalyst; and the polyether polyol is a mixture of polyethylene oxide polyol and polypropylene oxide polyol, and the compound catalyst is a compound of an organic tin catalyst and an amine catalyst. The low-temperature rapidly-vulcanized polyurethane high-temperature adhesive has the advantages of energy conservation and consumption reduction in the process of preparing a rubber floor mat, no harm to the environment and human bodies, and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of polyurethane adhesives, in particular to a low-temperature rapid vulcanization polyurethane high-temperature adhesive and its preparation method and application. Background technique [0002] With the development of science and technology and social economy, polyurethane materials have been applied to various fields of society, and polyurethane for paving has become the main member of polyurethane materials.
