Description
Technical field
The present invention relates to polymer composite, specifically a kind of producing and manufacturing technique without calcium high-purity layer of PVC pressing plate material being widely used in refinement high purity rare metal extraction tank.
Background technology
It is existing that for refining high purity rare metal, (as: purity is the yttrium oxide of 99.99%, cerium oxide, terbium sesquioxide, dysprosium oxide, Neodymium trioxide, europium sesquioxide and Erbium trioxide etc.) extraction tank usually adopt common PVC (Polyvinylchlorid, polyvinyl chloride) laminated plate material makes, because this common layer of PVC pressing plate material have employed more light calcium carbonate, therefore adopt the extraction tank that this common layer of PVC pressing plate material is made, when carrying out extraction process, easily in extraction solution, separate out calcium ion, the calcium concn that contains in extraction solution is caused usually to be greater than 0.5 μ g/ml, due to calcic excessive concentration in extraction solution, pole is unfavorable for the purification of rare metal, therefore the rare metal purity extracted with the extraction tank that this kind of common layer of PVC pressing plate material is made is not high, and extraction efficiency is low.
Summary of the invention
Object of the present invention is just to provide that a kind of good stability, degree of crosslinking are strong, the producing and manufacturing technique without calcium high-purity layer of PVC pressing plate material of purity when can significantly improve rare metal purification by liquid extraction and efficiency.
The present invention is made up of the raw material of following weight parts:
PVC resin powder 100, compound lead stabilizer 2-6, barium stearate 0.5-1.2, paraffin 0.2-0.7, chlorinatedpolyethylene 2-6, acrylate 2-6, coupling agent 2-5, ultra-fine barium sulfate 8-20.
Described coupling agent is silane coupling agent.
A kind of production technique without calcium high-purity layer of PVC pressing plate material of the present invention comprises following processing step:
A. by dosage, PVC resin powder is put in plastic hot mixing machine, then compound lead stabilizer, barium stearate, paraffin, chlorinatedpolyethylene, CALCIUM ACRYLATE is added successively, coupling agent and ultra-fine barium sulfate is added again after to be mixed, fully 4-6 minute is mixed in plastic hot mixing machine, when temperature is more than 95 DEG C, compound is dropped into cold stirring in machine to cool, be cooled to less than 45 DEG C;
B. the above-mentioned compound cooled is put in closed plastics processing mill and carry out banburying processing, banburying 5-7 minute in the temperature range of 165-180 DEG C;
C. the compound after banburying being machined is put in open type plastic purificating set and is carried out just refining processing, in the temperature range of 160-175 DEG C, just refine 2-3 minute;
D. the compound after just refining being machined drops in next open type plastic purificating set and carries out refining processing, refining 2-3 minute in the temperature range of 160-175 DEG C;
E. the compound after above-mentioned refining being machined is delivered in plastics tri-roll press machine and is rolled, and prepares sheet material; Control three roller roll spacings within 50-100 silk, temperature controls between 155-165 DEG C, preparation time 1-2 minute;
F. sheets of sizes is measured, hot-forming and get final product.
The present invention owing to have employed silane coupling agent in formula, and adopt ultra-fine barium sulfate to replace original light calcium carbonate, the silane coupling agent adopted can improve filler dispersiveness in the plastic, and can improve and the consistency of polyvinyl chloride resin and the compactness of surface contact, thus improve the mechanical property of plastics, and ultra-fine barium sulfate has satisfactory stability, therefore barium ion can not be separated out in extraction solution.Through practical application test, in extraction solution, be less than 0.4 μ g/ml containing calcium concn, therefore purity when greatly can improve rare metal purification by liquid extraction and efficiency, meet the requirement of rare-earth trade purification rare metal completely.
