Description
Technical field
The present invention relates to pottery and ceramic die industry, be specifically related to be used for the preparation method of the plastic mould material of forming process of ceramics.
Background technology
Gypsum mold is domestic ceramics and the traditional moulds used since the sanitary pottery industrial production midium or long term, because its low preparation cost and self-characteristic still are widely used in slip casting, spinning, roll extrusion, the plastic compression moulding processs such as (colding pressing) at present.Along with ceramic industry progressively to the development of mechanize and automatic production direction, the weak point of gypsum mold is also just more and more outstanding, for example intensity is low, work-ing life is short etc.Simultaneously because the quality of gypsum mold directly influences and has determined the quality of molding blank, and final decision the quality of product.Therefore, the limitation that gypsum material itself exists has restricted ceramic industry to high-quality, direction develops efficiently.
Mould of plastics has excellent performance; Good springiness for example in light weight, tough, good mechanical property, acid-alkali-corrosive-resisting, long service life etc. can be carried out car, mill, plane, mill, brill, various operations such as bonding; Be applicable to various moulding processs; But there are shortcomings such as water-absorbent difference in existing mould of plastics, is difficult to satisfy the demand of ceramic molding, has limited the use of mould of plastics in forming process of ceramics.
Summary of the invention
The present invention utilizes liquid phase pore-forming principle, and a kind of preparation method who is used for the plastic mould material of forming process of ceramics is provided.
The preparation method who is used for the plastic mould material of forming process of ceramics of the present invention comprises the steps:
The first step, in 100 parts of unsaturated polyesters, 20~30 parts of TEB 3Ks, 1~2 part of adding reaction kettle of tensio-active agent, controlled temperature stirred 15~25 minutes at 40 ℃~60 ℃;
Second step, in 10~20 parts of adding reaction kettles of polymethylmethacrylate, strengthen stirring velocity simultaneously, churning time is 20~30 minutes;
The 3rd step, treat that polymethylmethacrylate is uniformly dispersed after, add 2~5 parts of BPOs and 2~5 parts of mineral powders, continue to stir 15~30 minutes;
The 4th step added 10~40 parts in 2~5 parts of salt and silica gel, continued to strengthen stirring velocity;
The 5th step, continue to stir after 10~20 minutes, with the system cooling, slowly add 10~70 parts of entry and 2~5 parts of sodium laurylsulfonates to reaction system, after stirring, self-vulcanizing.
When step 2 added said polymethylmethacrylate in reaction kettle, repeatedly added preferred the branch in batches.
In the preferred lime carbonate of said mineral powder, polynite, talcum powder or the titanium oxide more than one.
In the preferred thionamic acid sodium of said salt, tetrabutylammonium perchlorate sodium or the disodium EDTA more than one.
The said cooling of step 5 preferably is reduced to 0~10 ℃.
Increasing stirring velocity according to the invention is: as long as the stirring velocity that guarantees step 2 big than step 1, the stirring velocity of step 4 gets final product greater than the stirring velocity of step 2, to the scope no requirement (NR).
The resulting forming process of ceramics of the present invention is used the plastic mould material good water absorption, can satisfy the requirement of ceramic molding.
