Description
Technical field
The present invention relates to a kind of bakelite and preparation method thereof, belong to Material Field.
Background technology
Bakelite is a kind of hard and crisp thermosetting plastics, is being commonly called as phenoplasts with wood powder as filler.Relative to general
Logical plastics, bakelite has high mechanical strength, and tough and hard wear resistant, dimensionally stable is corrosion-resistant, the features such as electrical insulation capability is excellent.With
Power system scale expands day by day, in the process of deployment of supply line, it is necessary to it is substantial amounts of using all kinds of insulating materials to line
Road is supported or connects, and wherein bakelite material has extremely wide application.
Water oxygen base in phenoplasts is strong to the compatibility of water, and easy moisture absorption, volumetric expansion after plastic moisture absorption produces planted agent
Power, meeting buckling deformation, general moisture absorption 3%, bending strength will reduce by 25% or so.As moisture content increases, impact strength is gradually
Improve, and tensile strength and bending strength are then substantially reduced.It is 100% in relative humidity, under temperature is 50 DEG C of wet heat condition,
The time that plastic part size reaches balance only has half under room temperature state.The material moulding plastics of water content 0.1%, its size is steady
Qualitative very poor, temperature reaches 150 DEG C, and phenolic aldehyde shrinkage of injection molded parts tends to be balanced, and again when rising, plastic may proceed to shrink temperature again,
That is existing bakelite size is unstable, and creep properties is big, is not suitable for use in high-precision mechanical and electric parts
Insulating materials.
Goal of the invention
It is an object of the invention to provide a kind of bakelite, with dimensionally stable, the characteristics of creep is small.
The present invention also aims to provide a kind of preparation method of bakelite.
Described bakelite, is made up of the raw material of following weight portion：Phenolic resin 80-100 parts, bakelite reclaimed materials
10-20 parts, nitrile rubber 5-10 parts, styrene-acrylic emulsion 3-7 parts, aluminium hydroxide 10-15 parts, polyethylene glycol 8-12 parts, benzene sulfonyl chloride
1-5 parts, odium stearate 7-12 parts, activate 10-20 parts of wood powder, kaolin 15-30 parts, 3-8 parts of aquamaine stone flour, glass fibre 30-
35 parts, asbestos 8-13 parts.
Described phenolic resin is aldehydes and phenols according to 1:1.4 mol ratio, the obtained first rank under base catalysis
Section resin.
Preferred bakelite, is made up of the raw material of following weight portion：90 parts of phenolic resin, bakelite reclaimed materials 15
Part, 7 parts of nitrile rubber, 5 parts of styrene-acrylic emulsion, 12 parts of aluminium hydroxide, 10 parts of polyethylene glycol, 3 parts of benzene sulfonyl chloride, 9 parts of odium stearate,
15 parts of wood powder of activation, 20 parts of kaolin, 5 parts of aquamaine stone flour, 32 parts of glass fibre, 10 parts of asbestos.
The preparation method of described bakelite, comprises the following steps：
1) inserts is prepared：
By 10-20 parts of bakelite reclaimed materials mechanical crushing to 100-200 mesh, then with aluminium hydroxide 10-15 parts, activation
Wood powder 10-20 parts, kaolin 15-30 parts, 3-8 parts of aquamaine stone flour, glass fibre 30-35 parts, asbestos 8-13 parts, odium stearate 7-
12 parts are sufficiently mixed uniformly, obtain inserts；
2) high-speed kneading is plasticated：
Phenolic resin and nitrile rubber are heated to molten state, are poured into inserts, under the conditions of 55-65 DEG C, with
After the rotating speed of 1000-1600r/min is stirred 30-50 minutes, by styrene-acrylic emulsion 3-7 parts, polyethylene glycol 8-12 parts, benzene sulfonyl chloride 1-
In 5 parts of addition inserts, continue to stir 3-5 hours；
3) finished product is extruded：
Material is delivered into mould press mold extrusion finished product.
Compared with prior art the beneficial effects of the invention are as follows：
The present invention uses SI semi-insulation bakelite reclaimed materials, not only solves bakelite and reclaims problem, and is conducive to drop
Low production cost；Addition nitrile rubber be conducive to improve product mechanical performance, with activate wood powder, kaolin, glass fibre with
And asbestos do filler, can make bakelite that there are dielectric properties higher, and avoid bakelite moisture expantion, styrene-acrylic emulsion and kyanite
Powder can at high temperature play a part of to offset and shrink as expansion component, the species and consumption by adjusting filler of the invention,
The stabilization of product size has been effectively ensured, creep is atomic small, thus bakelite of the present invention can extensively using make it is high-precision machinery and
The insulating materials of electric parts.
