Abstract
The invention discloses an organ silicone adhesive special for a fire-resistant mica tape, mainly made from MQ colophony, silicone rubber, organic solvent and strong base weak acid salt. The invention has good adhesion, holding power and softness, dryness, no recurrent viscosity, no moisture absorption and no carbon formation when being burned.
Description
Technical field:
The present invention relates to a kind of tackiness agent.
Background technology:
In today of rapid economic development, because the restriction of fire service and ability, a lot of fields all require the flame resistant cable that uses insulating property good.Flame resistant cable is different from common cable, and most importantly it has increased a flame retardant coating, and this flame retardant coating is arranged between conductor and the isolator usually.Cable is in a single day burned, and all organic materialss that constitute cable will be translated into ashes, and desire keeps " circuit integrity ", and what lean on is exactly this " flame retardant coating ".Flame retardant coating nearly all is to make of " fire-resistant isinglass belt ".The material that constitutes fire-resistant isinglass belt is mica paper, tackiness agent and supporting material glass wool cloth, and mica paper is the material that really plays electrical isolation and fire-resistant effect, and tackiness agent is the material that mica paper and glass wool cloth are combined into one.Tackiness agent select the bonding strength that must satisfy mica paper and glass wool cloth for use, the mica tape of making has certain flexibility and edge curvature degree, the principle of the low not charing of promptly burning of burning back carbon residue amount, the three is indispensable.
At present fire-resistant isinglass belt is base growth with the organic pressure-sensitive gel all with tackiness agent, has electrical insulating property, resistant of high or low temperature etc., mainly from import.The shortcoming that exists be dry and comfortable property poor, return sticking, the moisture absorption etc.
Summary of the invention:
The object of the present invention is to provide a kind of dry and comfortable, do not return sticking, nonhygroscopic, burning and do not analyse the special organosilicon adhesive for fire-resistant isinglass belt and the production method of charcoal.
Technical solution of the present invention is:
A kind of special organosilicon adhesive for fire-resistant isinglass belt is characterized in that: mainly made by following components in weight percentage:
MQ resin 10～30%
Silicon rubber 30～50%
Organic solvent 20～40%
Strong base-weak acid salt 0.005～0.02%.
Also be added with 0.1～10% stopper.
A kind of production method of special organosilicon adhesive for fire-resistant isinglass belt is characterized in that: comprise the following steps: successively
The silicon rubber of 30～50% weight, the MQ resin of 10～30% weight are dissolved in the organic solvent of 20～40% weight, put into three-necked flask, load onto stirring, thermometer and reflux condensing tube, open stirring, add strong base-weak acid salt and make condensation catalyst, reflux 6～8 hours gets product.
Also add 0.1～10% stopper in the product that obtains.
Product cohesiveness of the present invention is good, hold that viscous force is good, flexibility is good, dry and comfortable, it is sticking, nonhygroscopic not return, and charcoal is not analysed in burning.
The invention will be further described below in conjunction with embodiment.
