Problems solved by technology

[0002] The existing silicone oil production requires many raw materials, complex and changeable process, high loss, low product activity, poor catalytic effect, instability, and easy oxidation and deterioration. Deformation, low elongation, high cost, heavy odor, VOC detection does not meet the regulations; especially in some automated car cushion technology and the production of foam cushions with low density, short molding time and easy demoulding, due to the use of Incorrect silicone oil makes its foam less stable

Abstract

The invention provides high-resilience hydrogen-containing silicone oil. The silicone oil comprise, by weight, 60-75% of D4, 15-20% of epoxy resin and 5-10% of an additive. The invention further provides a preparation method of the high-resilience hydrogen-containing silicone oil. The method comprises the following steps that D4, the epoxy resin and the additive are mixed, stirred and heated, nitrogen is introduced into the mixture, a reaction is conducted for 15-18 h, and when mixed liquid after the reaction is clarified, the silicone oil is obtained. According to the preparation method, thenon-hydrolysis process of Si, O and C is short, the method is simple and easy to operate, few raw materials are needed, the price is low, the raw materials are easy to purchase, environmentally friendly, free of pollution and high in controllability, by adopting the pure natural catalyst epoxy resin, the risks such as pollution, oxidization, chemical component loss, waste residues, waste liquid, waste gas and catalytic effect reduction in the production process are avoided, and the silicone oil is safe and environmentally friendly; the high-resilience silicone oil is high in activity and suitable for automation automobile sitting cushion technologies and production of foam sitting cushions with low density, short molding time and easy demolding, the foam stability is high, and the processing range is wide.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a high resilience hydrogen-containing silicone oil and a preparation method thereof. Background technique [0002] The existing silicone oil production requires many raw materials, complex and changeable process, high loss, low product activity, poor catalytic effect, instability, and easy oxidation and deterioration. Deformation, low elongation, high cost, heavy odor, VOC detection does not meet the regulations; especially in some automated car cushion technology and the production of foam cushions with low density, short molding time and easy demoulding, due to the use of Incorrect silicone oil makes its foam less stable. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a high-rebound hydrogen-containing silicone oil, which can enhance foam stability and have a wider proc...
