Description
Technical field
The invention belongs to silicone adhesive sealant preparing technical fields, more particularly to high temperature resistant room temperature curing organosilicon
Sealant.
Background technology
Organic silicon adhesive is a kind of silicone composition with bonding and sealing function, by using different organic
Silicon polymer, additive and filler can obtain the silicon rubber composite wood of various requirement after room temperature, heating or radiation curing
Material.
It can be divided into organic silicon resin adhesive and organic silicone rubber adhesive two major classes by molecular structure, it can by curing mode
It is divided into condensed type and add-on type, aggretion type three classes, hot setting, low-temperature setting and room temperature curing three can be divided into again by solidification temperature
Class.
Organic siliconresin is as adhesive in use, common siloxanes (dimethyl silicone polymer, methyl triethyl group siloxanes
Deng) it is base-material, using tetraalkoxysilane and tetraalkoxy titanate esters crosslinking curing, it is suitable for building sealant, high-temperature plastic
Stick and low temperature resistant adhesive.Organic silicon rubber is generally room temperature curing type, there is two kinds of one pack system and bi-component, maximum spy
Point is with heat-resisting quantity.
Organic silicon adhesive is the staple product of adhesive and sealant industry.Adhesive downstream application extensively, product kind
The characteristics of class is various, and adhesive producing enterprise often concentrates on a kind of or several classes, the production and selling of product leads to China
The market concentration of Market of Adhesives is not high.Since developed countries enterprise starts to walk relatively early, to form in adhesive area
Certain first-strike advantage and the advantage of scale, occupies larger share in China Market of Adhesives.
Organic silicon adhesive product is widely used in building trade and industrial circle, with China's commercial real estate, urbanization
The needs of process and town and country construction have pulled consumption of the building trade to organic silicon adhesive, are that organic silicon adhesive is steady for a long time
Though fixed growth has been established solid foundation real estate speedup and slowed down, real estate construction area and the year-on-year speedup of completed floor space are all
It is maintained at 15% or more.Meanwhile organic silicon adhesive from it is single it is for building extended to multi-field, multipurpose, it is anti-in electric power
The fields such as corruption, automobile, electronic apparatus, new energy are found broad application, current non-organic silicon adhesive apparent consumption for building
Accounting has reached 40.5%.
From the point of view of subdivision field, in building trade, as the continuous propulsion of China's the Course of Urbanization and people are given birth to
Running water is flat to be improved, and is continued to increase to finishing, secondary decoration demand, organic silicon adhesive for building still has more wide market
Foreground, in addition, China's organic silicon adhesive high-end product is in terms of quality already close to international most advanced level, China is for building to be had
The export markets sales volume of machine silicon adhesive can be also stepped up.
In automobile industry, in recent years, China's automobile guarantee-quantity sustainable growth, 0.57 hundred million from 2007 reach 2015
1.72 hundred million, it is contemplated that the year two thousand twenty China's automobile guarantee-quantity will break through 200,000,000, and China's organic silicon adhesive demand will be with vapour
The growth of vehicle ownership and increase.In addition, in recent years, market is gradually perfect to small towns after China's automobile, this is to organic silicone adhesive
Agent demand also results in larger promotion.
Organic silica gel is the ideal encapsulating material of LED, with continuing to increase for LED illumination product permeability, it is contemplated that LED has
Machine silicium encapsulating material market demand future by keep 20% speedup.
In addition, China greatly develops the regenerative resources industry such as photovoltaic, wind-power electricity generation, organic silicon adhesive future
Demand will greatly be developed in the above field.In general, it is contemplated that arrive the year two thousand twenty China organic silicon adhesive year demand
Amount is up to 1,150,000 tons, and average growth rate per annum is up to 9.5% between 2015-2020.
It is base-material that existing silicone adhesive sealant, which is all made of hydroxyl-terminated injecting two methyl siloxane, with silica, is received
Rice calcium carbonate makees filler；Since hydroxyl is degradable in 250 DEG C of high temperature or more, strand produces fracture, and fluid sealant is caused to become fragile, glue
Relay is poor；300 DEG C of functions of losing fluid sealant completely.In order to change current condition, we use methoxy substitution terminal hydroxy group poly- two
Hydroxyl on methylsiloxane, cerium oxide, iron oxide red make refractory agent, when the fluid sealant produced is long with 300 DEG C of ranges
Between work, performance is constant.
