Isocyanuric ring-containing terminal hydrogenpolysiloxane

Abstract

The invention relates to a hydrogenpolysiloxane, shown as the formula (1), having isocyanuric ring, and has at least two terminal hydrogensiloxy: (X are mutually independent univalence organic group not containing unsaturated bonds, R are mutually independent methyl or phenyl, n is an integer from 1 to 50, m is an integer from 0 to 5, and P is an integer from 1 to 10). As the present invention is an isocyanuric ring-containing terminal hydrogenpolysiloxane having at least two hydrogensiloxys at ends, thus it is suitable for use in optical semiconductor sealants and the like agent.

Description

technical field The present invention relates to an organopolysiloxane having a hydrogen polysiloxane moiety at the terminal, capable of producing electrical properties such as heat resistance, mechanical strength, electrical insulation, gas permeability such as water vapor permeability resistance, and transparency. A hardened product with excellent optical properties such as optical properties, chemical resistance, and water resistance. Background technique Hitherto, hardening silicone rubber (siliconerubber) compositions using an addition curing reaction have been widely used. This curable silicone rubber composition is excellent in weather resistance, heat resistance, and electrical insulation, and is widely used as gasket materials, potting materials, and coatings for electrical and electronic parts. Molding materials such as coating materials, roll materials, and impression materials, materials for wire coating, and automotive parts materials. In addition, the optical...

Problems solved by technology

However, such a curable silicone rubber composition has a siloxane bond unique to silicone, so due to its ion binding property, there is a phenomenon that it is used under extremely severe conditions such as high temperature humidification. In the environment of use, the excellent characteristics of silicone such as chemical resistance, water resistance, and gas permeability cannot be exerted

Moreover, there are also the following disadvantages: the surface of the cured product is sticky, and it is easy to adhere to dust, etc.

This shows that the above-mentioned existing curable silicone rubber composition obviously still has inconvenience and defects in product structure and use, and needs to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
