Description
Technical field
The invention belongs to Material Field, and in particular to one kind methylates insulating rubber material.
Background technology
Insulating materials can divide gas, liquid, solid three major types.Conventional 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.By contrast, solid insulating material is numerous in variety, also mostly important；
Requirement of the different electrical equipments to insulating materials performance emphasizes particularly on different fields, high pressure electrical device such as high-voltage motor, high-tension electricity
The insulating materials requirement of cable etc. has high breakdown strength and low dielectric loss.Low-voltage electrical apparatus is then stretched with mechanical strength, fracture
Long rate, temperature classification etc. are used as major requirement；
The macro property of insulating materials such as electrical property, hot property, mechanical property, chemical-resistant resistance, weatherability change, corrosion-resistant etc.
Performance and its chemical composition, molecular structure etc. have substantial connection.Inoganic solids insulating materials is mainly by silicon, boron and a variety of gold
Belong to oxide composition, based on ionic structure, be mainly characterized in that heat resistance is high, operating temperature is generally higher than 180 DEG C, stability
Good, resistance to weathering, chemical proofing and the long-term ageing properties under electric field action are good；But fragility is high, impact resistance is strong
Degree it is low, high pressure and tensile strength is low；Manufacturability is poor.Organic material is generally polymer, and its heat resistance is usually less than inorganic material
Material.Material its heat resistance containing the element such as aromatic ring, heterocycle and silicon, titanium, fluorine is then higher than general line chain high polymer material；
With the development of society, increasing electric equipment enters in the family, factory, social environment of people, in order to
Allow people life more safety, it is necessary to insulation effect preferably, the more reliable insulating materials of performance meet electrical apparatus insulation
The requirement of energy, and elastomeric material is often used in as electrical equipment protective materials as conventional insulating materials, but it is easily old
Change, bin stability is poor, and the inorganic filler property compatible of addition is poor, greatly reduces the quality of finished product, reducing makes
Use security.
The content of the invention
It is an object of the invention to the easy aging for natural rubber in the prior art, bin stability is poor, and addition
The problem of inorganic filler property compatible is poor methylates insulating rubber material there is provided one kind.
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 rubber of 200-300 parts by weight, the age resistor rd mixing banburying 30-40s of 4-5 parts by weight, mixing temperature are 60-100 DEG C,
The chlorinated paraffin of 20-34 parts by weight is added, is kneaded 6-8 minutes, dumping, is cooled in 20-30 DEG C, input mill, adds
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 described 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, in the 1-METHYLPYRROLIDONE for being added to 7-10 parts by weight, stirs, send
Enter into 130-140 DEG C of oil bath, insulated and stirred 10-20 minutes, discharge, add the borax of 0.7-1 parts by weight, stir to normal
Temperature, obtains wax micro mist dispersion liquid；
（2）Organise the preparation of kaolin dispersion liquid
The kaolin of 13-20 parts by weight is taken, is calcined 1-2 hours at 700-800 DEG C, fine powder is worn into after cooling, 10- is added to
Soak 3-5 hours, discharge in 13mol/l sulfuric acid solution, washing, air drying is mixed with the aluminum stearate of 1-2 parts by weight,
Ultrasonic 10-20 minutes in carbon acid solution that be added to 3-4 times of compound weight, 20-25%, the kaolin that must organise disperses
Liquid；
（3）Esterification is kaolinic to be prepared
The kaolin dispersion liquid that organises is taken, mixes, stirs with the ethylene glycol solution of 8-hydroxyquinoline, be sent to polytetrafluoroethyl-ne
In alkene reaction kettle, insulation reaction 1-2 hours 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 obtained esterification kaolin, 0.2-0.4 parts by weight, is added to above-mentioned steps 1）It is made
Wax micro mist dispersion liquid in, stir, kaolin micro mist dispersion liquid must be esterified；
（5）The preparation of amination elastomer
SIS thermoplastic elastomer (TPE)s, the formamide mixing of 2-3 parts by weight of 27-30 parts by weight are taken, compound weight 1.6- is added to
In 2 times of absolute ethyl alcohol, insulated and stirred 1-2 hours at 60-65 DEG C, ethanol is distilled off, amination elastomer is obtained；
（6）Methylate the preparation of kaolin elastomer solution
Take step 4）Obtained esterification kaolin micro mist dispersion liquid, step 5）Obtained amination elastomer mixing, stirs, drips
Plus 18-20 parts by weight, the formalin that concentration is 10-14%, rise temperature is 60-70 DEG C, insulated and stirred 100-110 minutes,
Normal temperature is cooled to, must methylate kaolin elastomer solution.
Wherein, step 3）Described in 8-hydroxyquinoline ethylene glycol solution, it is prepared by the following method：Take 1-2 weight
In the 8-hydroxyquinoline of part, the ethylene glycol for being added to 18-20 times of its weight, stir.
Advantages of the present invention：
The present invention uses polyamide wax micropowder for raw material first, disperses in pyrrolidones, obtains wax micro mist dispersion liquid, while plus
Enter borax, improve the surface strength of micro mist, then mix the ethylene glycol solution of 8-hydroxyquinoline with kaolinic carbon acid solution
Reaction is closed, carbonic ester kaolin is obtained, while when kaolin is distributed into carbon acid solution, using aluminum stearate by kaolinite
Soil activation, improves the kaolinic forming stability of carbonic ester, and then thermoplastic elastomer (TPE) is handled using formamide, acyl is obtained
The elastomer of amination, is then mixed with formalin, by formalin and the cross-linking reaction of amidatioon elastomer, can be obtained
Methylolated elastomer, and while reaction, esterification kaolin micro mist dispersion liquid is also introduced, dimethyl carbonate can be with
As the auxiliary agent that methylates, the cross-link intensity of formalin and amidatioon elastomer is improved, while kaolin is had with elastomer
The combination of effect, improves dispersiveness, the compatibility of filler, so as to improve the stability_intensity of finished-product material, the elasticity of addition
Body has good buffering effect, can improve compression strength, the impact strength of finished product, and finished-product material insulation of the invention is steady
Qualitative good, bin stability is high, and safety in utilization is good, and combination property is superior.
