The invention relates to the field of processing of mica materials and provides a manufacturing method of a mica plate. The manufacturing method comprises the following steps of: pulping mica, gluing, adding auxiliary materials, pressing and the like. The manufacturing method of the mica plate, provided by the invention, has the advantages of simple process flow, high production efficiency and capacities of not only eliminating a paper-making process step and saving the cost for paper-making, but also effectively solving the layering quality problem of the mica plate.
Description
Technical field
The present invention relates to the mica material manufacture field, be specifically related to a kind of manufacture method of micarex.
Background technology
Micarex is a kind of insulating material of high-quality, have the advantages such as nontoxic, tasteless, high temperature resistant, high pressure resistant, ageing-resistant, corrosion-resistant, that electric property is stable, its good high-temperature insulation performance particularly, high-temperature resistant is up to 1000 ℃, in high-temperature insulation material, has good cost performance.Therefore be widely used in the fields such as household electrical appliance, chemical metallurgy.
Traditional micarex is, lamination bonding by mica paper and organosilicon glue, heat, suppress and form.This processing method need at first be produced mica paper, and operation is complicated.And the micarex of producing with the compacting of mica paper lamination is layer structure, easier layering distortion in using the course of processing.
Summary of the invention
The objective of the invention is provides a kind of manufacture method of micarex in order to solve the deficiency of prior art existence, and its technological process is simple, and production efficiency is high, not only greatly saved production cost, and the micarex that processes fully can layering.
The objective of the invention is to be achieved by the following technical measures.
A kind of manufacture method of micarex, the method may further comprise the steps:
(1) with the mica raw material through the broken pulping of high-pressure hydraulic pulping equipment, be crushed to certain granularity, particle size range is between 74 microns to 500 microns, mica is divided into mica flake by stripping in this step;
(2) mica flake that obtains in the above-mentioned steps (1) is arranged in pairs or groups according to granule size, mix with adhesive after allotting the mica slurry of suitable making sheet, binder content is 10 ~ 50% of mica slurry, utilize mixer that mica slurry and adhesive are fully stirred, mixing time 30 ~ 50 minutes, mixing speed per minute 10 ~ 20 turns; The proportioning structure of above-mentioned mica flake is:
8-40 order 12-15%
40-80 order 15-18%
80-120 order 60%
120-200 order 10%;
(3) mixture that stirs in the step (2) is mixed with strengthening auxiliary material, carry out at last the high temperature compacting and can obtain micarex through uniform temperature and pressure, wherein temperature is 260 ° of C, and pressure is 20Mpa.
In technique scheme, the mica raw material described in the step (1) is muscovite or phlogopite.
In technique scheme, the adhesive described in step (2) or (3) is organic siliconresin glue.
In technique scheme, the enhancing auxiliary material described in the step (3) is glass fabric etc.
The manufacturing approach craft flow process of micarex of the present invention is simple, and production efficiency is high, not only can save the papermaking operation, saves the cost that papermaking spends, and can also effectively solve the layering quality problems of micarex.Conventional method is layer structure with the micarex of mica paper production, and the micarex that the inventive method is produced is to take clean forming by mica flake fully, therefore fully can layering, can be used for producing the thickening type micarex.
Description of drawings
Fig. 1 is the manufacture method flow chart of micarex of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, present embodiment provides a kind of manufacture method of micarex, and the method may further comprise the steps:
(1) with the mica raw material through the broken pulping of high-pressure hydraulic pulping equipment, be crushed to certain granularity, particle size range is between 74 microns to 500 microns, mica is divided into mica flake by stripping in this step;
(2) mica flake that obtains in the above-mentioned steps (1) is arranged in pairs or groups according to granule size, mix with organic siliconresin after allotting the mica slurry of suitable making sheet, organic siliconresin content is 10 ~ 50% of mica slurry, utilize mixer that mica slurry and organic siliconresin are fully stirred, mixing time 30 ~ 50 minutes, mixing speed per minute 10 ~ 20 turns;
(3) mixture that stirs in the step (2) is removed too much organic siliconresin after auxiliary material mixes with strengthening, carry out at last the high temperature compacting and just can directly become plate through behind uniform temperature and the pressure, wherein temperature is 260 ° of C, and pressure is 20Mpa.
In the above-described embodiments, described mica flake proportioning structure is:
8-40 order 12-15%
40-80 order 15-18%
80-120 order 60%
120-200 order 10%.
In the above-described embodiments, described mica raw material is muscovite or phlogopite.
In the above-described embodiments, described enhancing auxiliary material is glass fabric etc.
The described technique of present embodiment is different from traditional mask-making technology, the tradition mask-making technology is to suppress after the mica paper gluing, the defective of the method is exactly the film that exists two-layer gluing to produce between mica paper and the mica paper, and film bubbles easily when being subject to temperatures involved, thereby makes the mica paper layering; And the described mask-making technology of the inventive method is directly mica flake to be pressed into plate, the centre does not have the papermaking link, therefore when being subject to temperatures involved, can not produce lamination, this technique is through test of many times, process conditions are strict, and the parameters such as reaction temperature, spread have strict demand, especially added to make behind the enhancing auxiliary material mica flake strengthen adhesion, directly becoming plate, is a kind of innovation of mica mask-making technology.
Specific embodiment described herein only is to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
