Abstract
The invention discloses an antiflaming one-component modified silane (MS) polyether sealant and a preparation method thereof. The sealant comprises an MS premix compound, a cross-linking agent, a coupling agent and a catalyst, wherein the MS premix compound consists of MS-polymer resin, a plasticizer, antiflaming packing, reinforcement packing, a thixotropic agent and a performance assistant. The preparation method comprises the steps that the MS premix compound, the cross-linking agent, the coupling agent and the catalyst are dispersed uniformity, and the efficiently antiflaming one-component modified silane polyether sealant is obtained.
Description
technical field [0001] The invention relates to a sealant and a preparation method thereof, in particular to a preparation method of a flame-retardant one-component silane-modified polyether sealant. In particular, it involves the bonding and sealing of devices with relatively high requirements for flame retardancy. Background technique [0002] As the basic polymer of silyl-terminated polyether sealants (silyl-terminated polyoxypropylene, also known as MS polymer), it was first developed and listed by Japan Zhongyuan Chemical Industry Co., Ltd. in 1979, and successively developed silyl-terminated polyols. ether sealant. In 1980, it won the Science and Technology Award of the Polymer Society of Japan. In 1981, it began to be popularized and applied in large buildings, and achieved good results. Then, a number of companies have successively developed a series of modified silicone elastic sealants, which laid a good foundation for the rapid development of silane-based polyet...
