Description
Technical field
The invention belongs to Material Fields, and in particular to one kind methylates insulating rubber material.
Background technology
Insulating materials can divide gas, liquid, solid three categories.Common gas insulating material has air, nitrogen, lithium
Sulphur etc..Liquid insulating material mainly has mineral insulating oil, synthetic insulating oil（Silicone oil, detergent alkylate, polyisobutene, isopropyl
Biphenyl, diarylethane etc.）Two classes.Solid insulating material can be divided to organic and inorganic two class.Organic solid insulating materials includes insulation
Paint, insulating cement, insulating paper, non-conductive fibre product, plastics, rubber, varnished cloth paint pipe and insulation impregnating fibre, electrician are with thin
Film, composite article and adhesive tape, electrician's laminated product etc..Inoganic solids insulating materials mainly has mica, glass, ceramics and its system
Product.In contrast, solid insulating material is numerous in variety, also mostly important；
Requirement of the different electrical equipments to insulating material properties emphasizes particularly on different fields, high pressure electrical device such as high-voltage motor, height
The insulating materials requirement of voltage cable etc. has high breakdown strength and low dielectric loss.Low-voltage electrical apparatus is then with mechanical strength, disconnected
Elongation, temperature classification etc. are split as major requirement；
The macro property of insulating materials such as electrical property, hot property, mechanical property, chemical-resistant resistance, weatherability variation, corrosion resistant
The performances and its chemical composition, molecular structure etc. such as erosion have substantial connection.Inoganic solids insulating materials is mainly by silicon, boron and more
Kind metal oxide composition based on ionic structure, is mainly characterized in that heat resistance height, and operating temperature is generally higher than 180 DEG C, surely
It is qualitative good, resistance to weathering, chemical resistance and the ageing properties under electric field action are good for a long time；But brittleness is high, resistance to punching
Hit intensity is low, high pressure and tensile strength is low；Craftsmanship is poor.Organic material is generally polymer, and heat resistance is usually less than nothing
Machine material.Material its heat resistance containing the elements such as aromatic ring, heterocycle and silicon, titanium, fluorine is then higher than general line chain high molecular material；
With the development of society, more and more electrical equipments enter in the family, factory, social environment of people, in order to
People’s lives more safety can be allowed, it is necessary to which the insulating materials that insulation effect is better, performance is more reliable is exhausted to meet electric appliance
The requirement of edge performance, and rubber material is often used in as electric appliance protective materials, however it is easily as common insulating materials
Aging, bin stability is poor, and the inorganic filler property compatible added is poor, greatly reduces the quality of finished product, reduces
Safety in utilization.
The content of the invention
It is an object of the invention to be directed to the easy to aging of natural rubber in the prior art, bin stability is poor, and add
The problem of inorganic filler property compatible is poor provides one kind and methylates insulating rubber material.
To achieve the above object, the present invention uses following technical scheme：
One kind methylates insulating rubber material, the insulating rubber material that methylates by the kaolin elastomer solution that methylates,
With the natural rubbers of 200-300 parts by weight, anti-aging agent rd mixing the mixing 30-40s, mixing temperature 60-100 of 4-5 parts by weight
DEG C, the chlorinated paraffin of 20-34 parts by weight is added in, is kneaded 6-8 minutes, dumping, is cooled to 20-30 DEG C, is put into open mill, is added in
The zinc oxide of 0.7-1 parts by weight, the sulphur of 2.8-3 parts by weight, 3-4 parts by weight captax BS, thin logical 3-5 all over and be made.
Wherein, the kaolin elastomer solution that methylates is made by following steps：
（1）The preparation of wax micro mist dispersion liquid
The polyamide wax micropowder of 1-3 parts by weight is taken, is added in the N-Methyl pyrrolidone of 7-10 parts by weight, stirring is equal
It is even, it is sent in 130-140 DEG C of oil bath, insulated and stirred 10-20 minutes, discharges, add in the borax of 0.7-1 parts by weight, stirring
To room temperature, wax micro mist dispersion liquid is obtained；
（2）Organise the preparation of kaolin dispersion liquid
The kaolin of 13-20 parts by weight is taken, when calcining 1-2 is small at 700-800 DEG C, fine powder is worn into after cooling, is added to
It when immersion 3-5 is small in the sulfuric acid solution of 10-13mol/L, discharges, washing, air drying is mixed with the aluminum stearate of 1-2 parts by weight
It closes, 10-20 minutes ultrasonic in carbon acid solution that be added to 3-4 times of mixture weight, 20-25%, the kaolin that must organise point
Dispersion liquid；
（3）It is esterified kaolinic preparation
The kaolin dispersion liquid that organises is taken, mixes, stirs evenly with the ethylene glycol solution of 8-hydroxyquinoline, is sent to poly- four
In vinyl fluoride reaction kettle, when insulation reaction 1-2 is small at 90-100 DEG C, discharge, dehydration, air drying obtains esterification kaolin；
（4）It is esterified kaolin micro mist dispersion liquid
Take step 3）The stannous octoate mixing of esterification kaolin, 0.2-0.4 parts by weight obtained, is added to above-mentioned steps 1）
It in wax micro mist dispersion liquid obtained, stirs evenly, kaolin micro mist dispersion liquid must be esterified；
（5）The preparation of amination elastomer
The formamide mixing of the SIS thermoplastic elastomer (TPE)s, 2-3 parts by weight of 27-30 parts by weight is taken, is added to mixture weight
In 1.6-2 times of absolute ethyl alcohol, when insulated and stirred 1-2 is small at 60-65 DEG C, ethyl alcohol is distilled off, obtains amination elastomer；
（6）Methylate the preparation of kaolin elastomer solution
Take step 4）It is obtained to be esterified kaolin micro mist dispersion liquid, step 5）Amination elastomer mixing obtained, stirring are equal
Even, formalin that 18-20 parts by weight are added dropwise, that concentration is 10-14%, rise temperature is 60-70 DEG C, insulated and stirred 100-110
Minute, it is cooled to room temperature, must methylate kaolin elastomer solution.
Wherein, step 3）Described in 8-hydroxyquinoline ethylene glycol solution, prepare by the following method：Take 1-2 weight
The 8-hydroxyquinoline of part, is added in the ethylene glycol of 18-20 times of its weight, stirs evenly.
Advantages of the present invention：
The present invention uses polyamide wax micropowder as raw material first, disperses in pyrrolidones, obtains wax micro mist dispersion liquid, together
When add in borax, improve the surface strength of micro mist, it is then that the ethylene glycol solution of 8-hydroxyquinoline and kaolinic carbonic acid is molten
Liquid hybrid reaction obtains carbonic ester kaolin, while when kaolin is distributed to carbon acid solution, it will using aluminum stearate
Activation of kaoline improves the kaolinic forming stability of carbonic ester, and then thermoplastic elastomer (TPE) is handled using formamide, is obtained
To amidated elastomer, then mixed with formalin, it, can be with by the cross-linking reaction of formalin and amidation elastomer
Methylolated elastomer is obtained, and while reaction, esterification kaolin micro mist dispersion liquid is also introduced, dimethyl carbonate is also
Can be used as and methylate auxiliary agent, improve the cross-link intensity of formalin and amidation elastomer, at the same by kaolin with it is elastic
Body is effectively combined, and improves dispersiveness, the compatibility of filler, so as to improve the stability_intensity of finished-product material, addition
Elastomer has good buffering effect, can improve compression strength, the impact strength of finished product, and finished-product material of the invention is exhausted
Edge stability is good, and bin stability is high, and safety in utilization is good, and comprehensive performance is superior.
