Abstract
The invention is a kind of PTC temperature self-control ceram special glue, which is made up of 100 shares of polydi organic group oxosilane, 5-50 shares of reinforcement fillers, 100-450 shares of heat conducting materials, 3-50 shares refractory additives, 0.03-10 shares of polymerization inhibitor, 3-100PPM catalyst, 1-15 shares of cross linker. It has excellent heat conducting property, and self-cancelling property, it can be applied to PTC temperature self-control ceram and the electro-heat element.
Description
The present invention relates to a kind of PTC be carried out PTC that bonding, sealing and embedding use from temperature control pottery special adhesive from temperature control pottery and electrical heating element.
PTC is a kind of novel heating unit of excellent performance from temperature control heating pottery, energising back PTC sheet can be transformed into heat energy to electric energy, and behind the arrival design temperature, the resistance of PTC sharply increases, thereby stop energising and heating, can recover energising and heating after temperature descends again automatically.The highest heating temp of PTC sheet reaches more than 300 degree centigrade, can satisfy the needs of a lot of electrically heated products, but just can not keep the above-mentioned performance of PTC when with common heat-conducting silicon rubber above-mentioned PTC sheet being carried out bonding, sealing or embedding.
Summary of the invention
Can solidify rapidly after the purpose of this invention is to provide a kind of heating, adhesiveproperties is good, the thermal conductivity height, and the PTC that high temperature resistant aging, fire-retardant and self-extinguishing can be strong is from the special adhesive of temperature control pottery and electrical heating element.
Concrete technical scheme of the present invention is as follows: it is sizing that the present invention adopts poly-diorganosiloxane, adds reinforced filling, thermally conductive material, high temperature resistant additive, stopper, catalyzer and linking agent.Wherein each component is: 100 parts of poly-diorganosiloxanes, 5～50 parts of reinforced fillings, 100～450 parts of thermally conductive materials, 3～50 parts of high temperature resistant additives, 0.03～10 part of stopper; Being divided into two components packings of equiponderant A, B after the above-mentioned base-material mixing.Also visual each proportioning composition situation of the weight of A, B two components and determine its part by weight.In the A component, add the catalyzer coordination thing of 3～100PPM (calculating), in the B component, add 1～15 part of multiple crosslinking agent with platinum.
The viscosity of the poly-diorganosiloxane that the present invention uses is 0.5～100PaS, and its end group can be selected allyl group for use, methyl diallyl, triallyl, vinyl, methyl, one or more in the methyl ethylene phenyl; Its organic radical can be selected methyl, phenyl for use, and one or more in the vinyl generally select for use wherein multipolymer as basic glue.
The reinforced filling that the present invention uses can be selected the aerosil through special processing, precipitated silica, silica powder, one or more mixtures in the MQ silicone resin for use.
The thermally conductive material that the present invention uses can be selected silicon carbide for use, aluminium powder, and aluminium nitride, boron nitride, magnesium oxide, zinc oxide, cupric oxide, aluminum oxide, nickel oxide, titanium oxide, antimonous oxide, one or more in the zirconium silicon oxide W powder, granularity is 0.5～50 μ m..
The high temperature resistant additive that the present invention uses can be selected the gaseous oxidation titanium for use, high-purity cerium dioxide, high purity ferric oxide and derivative thereof, ironic hydroxide, any in iron, the tin composite or several mixtures.
The stopper that the present invention uses can be selected the alkynol class for use, vinyl cyclosiloxane polymer-modified, pyridines, quinoline, triphenylphosphine, a kind of in the extraordinary maleic acid ester or several.
The catalyzer that the present invention uses can be selected the coordination thing of platinum for use, as vinylsiloxane, and vinyl cyclosiloxane, the coordination thing of allyl group polysiloxane or the microcapsule of platinum, the complex compound of platinum and two triallyl tetramethyl disiloxanes.
The linking agent that the present invention uses can be selected end hydrogen base polydimethylsiloxane for use, Methyl Hydrogen Polysiloxane Fluid, a kind of in terminal methyl polymethyl hydrogen siloxane and the chain extension thing thereof or several.
As long as A, B two components packing opened base-material can use after fully mixed, the sizing material after mixing is no less than 5 days in duration of service in summer, is no less than 7 days in the winter time duration of service in use in the present invention.This special adhesive can replace expensive import glue in a large number in the bonding industry of PTC, can be widely used in the various electrically heated products such as air-conditioning, warm-air drier, super bath, Electric heating box, electric mosquito repellent, electrothermostat, shoe baking device, use that this gluingly connects, the PTC electrically heated product of sealing and embedding, can keep the various technical features of former PTC from the temperature control pottery.It is high temperature resistant aging that special adhesive of the present invention has reached, and can solidify rapidly after heating, and adhesiveproperties is good, and the thermal conductivity height is high temperature resistant aging, fire-retardant and technical requirement that self-extinguishing can wait by force.
Be embodiments of the invention below:
It is the poly-diorganosiloxane of two triallyls of 35PaS that poly-diorganosiloxane is selected viscosity for use, and its organic radical is a methyl ethylene, dimethyl, phenylbenzene, 100 parts; Reinforced filling is selected for use through 10 parts of the fumed silicas of special processing with through 10 parts of the precipitated silica of special processing; Thermally conductive material is selected 350 parts in silicon carbide for use; High temperature resistant additive is selected 8 parts of high-purity cerium dioxides for use; Stopper is selected 3 parts of alkynol classes for use.Above each base-material is mixed the back as basic glue, with A, B two components of weight such as above-mentioned basic glue is divided into.The catalyzer coordination thing that adds in the A component is a platinum and 0.7 part in the complex compound of two triallyl tetramethyl disiloxanes.The multiple crosslinking agent that adds in the B component is for holding 25 parts of 20 parts of hydrogen base polydimethylsiloxanes and Methyl Hydrogen Polysiloxane Fluids.During use above-mentioned A, B two components evenly can be used so that 1: 1 weight ratio is mixed.
