Abstract
The invention discloses a high temperature resistant polyvinyl chloride (PVC) granular material and a preparation method thereof. The granular material is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 10-20 parts of high temperature resistant acrylic (ACR) additives, 5-8 parts of a calcium and zinc stabilizer and 1-3 parts of polyethylene wax. The preparation method comprises the following steps: stirring the PVC resin, the high temperature resistant ACR additives, the calcium and zinc stabilizer and the polyethylene wax, together with black dry powder or red dry powder, in a stirrer, and heating; adding the obtained mixture in a hopper; and extruding and granulating through a granulator to obtain the high temperature resistant PVC granular material.
Description
Technical field:
The present invention relates to plastic products technology field, is specifically a kind of high temperature resistant PVC particulate material and preparation method thereof.
Background technology:
PVC material is polyvinyl chloride, and it is one of plastic prod of output maximum in the world, and low price, is widely used, and polyvinyl chloride (PVC) RESINS is white or buff powder.Can add different additives according to different purposes, igelite can present different physicalies and mechanical property.In polyvinyl chloride (PVC) RESINS, add appropriate softening agent, can be made into multiple hard, soft and transparent article.Igelite has good mechanical property, wear resistance, resistance to chemical corrosion, and can be made into multiple articles for daily use is general plastics that a kind of cost performance is the most superior.But the high thermal resistance of PVC material of the prior art is bad.
Summary of the invention:
Technical problem to be solved by this invention is that a kind of high temperature resistant PVC particulate material is provided.
Another object of the present invention is to provide a kind of preparation method of high temperature resistant PVC particulate material, the PVC particle high thermal resistance of being made by this preparation method is good, and this preparation method's technique is simple, easy to operate.
Technical solution of the present invention is, a kind of high temperature resistant PVC particulate material is provided, and it is to be prepared from by the raw material of following portions by weight,
100 parts of polyvinyl chloride resins;
High temperature resistant ACR auxiliary agent 10-20 part;
Calcium zinc stabilizer 5-8 part;
Polyethylene wax 1-3 part.
As a preferred embodiment of the present invention, wherein the weight proportion of each raw material is,
100 parts of polyvinyl chloride resins;
10 parts of high temperature resistant ACR auxiliary agents;
5 parts of calcium zinc stabilizers;
2 parts of polyethylene waxs.
Further, it also comprises and comprises 1 part, 2 parts, black dry powder or red dry powder.Be used for being manufactured with coloured particles.
The present invention also provides a kind of preparation method of high temperature resistant PVC particulate material, the method comprises the steps, first, polyvinyl chloride resin, high temperature resistant ACR auxiliary agent, calcium zinc stabilizer, polyethylene wax are put into stirrer together with black dry powder or red dry powder, stir 3-7 minute, heating continues to stir and reaches 100 DEG C to temperature of charge in 2 minutes; Then above-mentioned compound is put into hopper, through tablets press extruding pelletization, i.e. the described high temperature resistant PVC particle of system.
As preferably, the mode that described tablets press drenches thermal baffle by water is lowered the temperature.Energy-conserving and environment-protective.
Compared with prior art, the present invention has the following advantages in the present invention: by above-mentioned material proportion, making can resistant to elevated temperatures PVC particulate material, and this preparation method's technique is simple, easy to operate.
Embodiment:
With regard to embodiment, the invention will be further described below:
Embodiment 1
A kind of high temperature resistant PVC particulate material, first polyvinyl chloride resin 100Kg, high temperature resistant ACR auxiliary agent 10Kg, calcium zinc stabilizer 5Kg, polyethylene wax 2Kg, black dry powder 2Kg are put into together to stirrer and stir, time is 5 minutes, and heating continues to stir and reaches 100 DEG C to temperature of charge in 2 minutes; Then above-mentioned compound is put into hopper, through tablets press extruding pelletization, i.e. the described high temperature resistant PVC particle of system.High temperature resistantly reach 80 DEG C.
It should be noted that, calcium zinc stabilizer wherein also can adopt calcium salt stablizer and zinc salt stablizer to substitute, and in addition, high temperature resistant ACR auxiliary agent model is LS-60.In addition, the mode that tablets press drenches thermal baffle by water is lowered the temperature.
Embodiment 2
Identical with preparation method in embodiment 1, there is following difference,
Polyvinyl chloride resin 102Kg, high temperature resistant ACR auxiliary agent 12Kg, calcium zinc stabilizer 6Kg, polyethylene wax 3Kg, red dry powder 1Kg.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
