Problems solved by technology

[0003] When it is prepared, it needs to be synthesized by chemical reaction, and when it is synthesized, the heating method generally chooses water bath heating. For water bath heating, its advantage is that it is heated evenly. In the prior art, water bath heating mostly adopts fixed or dead water heating. Heating by means of water, because in water, heat transfer takes a certain amount of time, because it will form a temperature gradient between the heat source and the heating place, on the one hand, the heat transfer efficiency is low, on the other hand, its heating uniformity needs to be improved

Abstract

The invention discloses a mesoporous silicon oxide modified polyurethane elastomer and a production device thereof, and relates to the technical field of chemical synthesis. The invention aims to solve the problem of heating efficiency. The device comprises a base, connecting springs are welded to the outer walls of the four corners at the top of the base, an overflow box is welded to the outer walls of the tops of the connecting springs, a water bath box is fixedly connected to the inner wall of the bottom of the overflow box through supporting legs, and an electric heating box is fixed to the outer wall of the top of the base through bolts; the elastomer comprises polyether polyol, isocyanate, small molecular diol, a chain extender, ethyl silicate and a silane coupling agent. According to the invention, flowing water is used for heating materials in the water bath box, the heating efficiency can be improved to a certain degree, the whole water flow direction is set as a loop, water recycling can be achieved, in addition, the overflow box is flexibly connected with the base through the connecting springs, and when a vibration motor is started, water in the water bath box can be vibrated; and the heating efficiency and the heating uniformity are improved.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a mesoporous silicon oxide modified polyurethane elastomer and a production device thereof. Background technique [0002] Polyurethane is usually formed by addition polymerization of polyether or polyester macromolecular polyol, polyisocyanate and small molecule polyamine or polyol chain extender. The soft and hard segment structure in the macromolecular chain and the microscopic phase of the material The characteristics of separation make polyurethane have excellent mechanical properties, and can be made into (foam) plastics, elastomers, fibers, coatings and adhesives, etc. Among them, polyurethane elastomer is a kind of polymer synthesis between general rubber and plastic. The material has the high strength of plastic and the high elasticity of rubber. Its outstanding performance is reflected in its excellent wear resistance, oil resistance, low temperature resistanc...
