Abstract

The invention discloses a making method of mildew-proof insulating mica paper. The mildew-proof insulating mica paper is prepared from the following materials in parts by weight: 130-140 parts of mica, 1-2 parts of sodium carboxymethyl cellulose, 1-2 parts of sodium metasilicate, 1-2 parts of soybean oil, 10-12 parts of kaolin powder, 1-2 parts of golden cypress powder, 4-6 parts of polyvinyl alcohol, 1-2 parts of methyl triethoxysilane, 1-2 parts of aminopropyl triethoxysilane, 3-4 parts of polyvinyl acetate emulsion, 1-2 parts of ammonium persulfate and a proper amount of water. The golden cypress powder is increased into the formula of the mildew-proof insulating mica powder, so that a certain antibacterial mildew-proof effect is achieved, and the advantages of puncture resistance, high insulation, thermal insulation and the like of the natural mica are kept. Besides, the mica paper which is made by the manufacturing method disclosed by the invention has good electrical strength and tensile strength.

Description

The manufacture method of antifungus insulation mica paper

Technical field

The present invention relates to the mica paper production technical field, particularly a kind of manufacture method of antifungus insulation mica paper.

Background technology

Mica is a kind of laminar silicic acid salt mineral of Nature creating, the characteristic that has good physical property and electrical resistance and still keep above performance under the condition of high temperature, it has chemical inertness and low flammability completely, the most important thing is that it has anti-high voltage, corona-resistant and radiation-resistant characteristic.

Mica paper is to take fractus master slice (muscovite, phlogopite, artificial mica synthesis) to be raw material, with chemical pulping or hydraulic slurrying, copy into paper roll under the slower speed of a motor vehicle of cylinder mould machine, cut into again roll web or sheet paper, mica paper has kept the premium properties of natural mica, and even thickness, the dielectric strength fluctuation range is little, corona inception voltage is high and stable; The voltage characteristic of its dielectric loss is much more stable than the mica splitting insulation, and thermal conductivity is good.

But it is single to produce at present mica paper technique, adopt fecula or ripe powder production, electrical strength and the TENSILE STRENGTH of mica paper are undesirable, need the new production technology of research.

Summary of the invention

The manufacture method that the purpose of this invention is to provide a kind of antifungus insulation mica paper.

Technical scheme of the present invention is as follows:

A kind of manufacture method of antifungus insulation mica paper is characterized in that: the raw material by following weight portion is made: mica 130-140, sodium carboxymethylcellulose 1-2, sodium metasilicate 1-2, soybean oil 1-2, kaolin powder 10-12, golden cypress powder 1-2, polyvinyl alcohol 4-6, MTES 1-2, aminopropyl triethoxysilane 1-2, polyvinyl acetate emulsion 3-4, ammonium persulfate 1-2, water are appropriate;

Comprise the following steps:

(1) by mica 700-800 ℃ of lower high-temperature calcination, calcine 1-2 hour the mica grog;

(2) grog is added to the Silane coupling agent KH550 that is equivalent to grog weight 3-4%, the sodium phosphate trimer of 2-3%, pulverize, obtain 50-120 order powder;

(3) by grog powder and other surplus stock mixing and water adding, to moisture be 40-50%, be heated to 80-90 ℃, stirring reaction 1-2 hour;

(4) step (3) slurry is diluted to clinker content 3-4%, adds the oxide powder and zinc that is equivalent to grog powder weight 4-5%, dispersed with stirring is even, the cylinder copy paper;

(5) dry: gained paper is dried to moisture 0.2 ~ 0.5% and is got product in drying cylinder.

In the present invention formula, increased the golden cypress powder, had certain antibacterial and mouldproof effect, kept again natural mica to resist wearing, high insulation, the advantage such as heat insulation, mica paper electrical strength and TENSILE STRENGTH that the present invention makes are good.

The specific embodiment

A kind of manufacture method of antifungus insulation mica paper, by the raw material of following weight portion (kilogram), made: mica 130, sodium carboxymethylcellulose 2, sodium metasilicate 1, soybean oil 1, kaolin powder 10, golden cypress powder 2, polyvinyl alcohol 4, MTES 2, aminopropyl triethoxysilane 1, polyvinyl acetate emulsion 4, ammonium persulfate 1, water are appropriate;

Comprise the following steps:

(1) by mica 700-800 ℃ of lower high-temperature calcination, calcine 1-2 hour the mica grog;

(2) grog is added to the Silane coupling agent KH550 that is equivalent to grog weight 4%, 2% sodium phosphate trimer, pulverize, obtain 50-120 order powder;

(3) by grog powder and other surplus stock mixing and water adding, to moisture be 40-50%, be heated to 80-90 ℃, stirring reaction 1-2 hour;

(4) step (3) slurry is diluted to clinker content 3-4%, adds the oxide powder and zinc that is equivalent to grog powder weight 5%, dispersed with stirring is even, the cylinder copy paper;

Dry: gained paper is dried to moisture 0.2 ~ 0.5% and is got product in drying cylinder

The mica paper that the present invention makes, TENSILE STRENGTH are 2.1KN/m, breakdown voltage 44KV/mm.
