Abstract
The invention discloses novel red polyvinyl chloride paste resin. The novel red polyvinyl chloride paste resin has the advantages that the toxicity in the heating process of processing the red polyvinyl chloride paste resin into plastic finished products is reduced; the required temperature in the product manufacturing process is also lowered; the heating time is reduced; and the energy consumption of enterprises using the red polyvinyl chloride paste resin is reduced, the production efficiency is improved, and the production cost is reduced, so the energy-saving and environmental-friendly standards of the use enterprises are improved. The technical scheme adopted by the novel red polyvinyl chloride paste resin provided by the invention mainly comprises four major steps including heating container preheating, constant-temperature heating, natural cooling and grinding.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of novel red pvc resin paste grade.
Background technology
pvc resin paste grade is the large class in polyvinyl chloride (PVC) RESINS (PVC), and pvc resin paste grade granularity is fine, and size range is generally at 0.1～2.0 μ m, and quality, as talcum powder, has immobility, and this kind of resin mainly applied to make pasty state form.Pvc resin paste grade mixes by stirring and forms stable suspension with softening agent, make PVC thickener, under low normal pressure and temperature, make the shape of plastic prod, then by heating, make thickener gelation, after cooling again, can make plastic product, prior art is used for being processed into final plastics with this form exactly.
the pvc resin paste grade circulating on market is now in being processed into the heat-processed of plastic product, and pvc resin paste grade can decomposite hydrogen chloride gas at leisure, and this gas is harmful.And make the temperature required height of heating in plastic product process, heat-up time is long, allows and uses enterprise energy consumption to increase, and has reduced production efficiency, has improved production cost, thereby allow, uses enterprise can not reach the standard of energy-conserving and environment-protective.
in order to improve competitive edge, existing finished product processing enterprise is more and more higher to the requirement of raw material, more needs a kind of moisture content few, and solvability is high, and absorptivity is good, sticks with paste viscosity large, the pvc resin paste grade raw material that hardness is high.
Summary of the invention
the present invention is in order to address the above problem, a kind of novel red pvc resin paste grade is disclosed, red pvc resin paste grade of the present invention has not only reduced the toxicity being processed in plastic product heat-processed, also in making product process, reduced temperature required, reduce heat-up time, allow and use the enterprise energy consumption of red pvc resin paste grade of the present invention to reduce, improved production efficiency, reduce production cost, thereby allow, used enterprise to improve the standard of energy-conserving and environment-protective.
novel red pvc resin paste grade making method of the present invention is:
1. preheating heating container: container needs preheating before putting into raw material, makes internal tank preheating temperature to 50-150 ℃;
2. thermostatically heating: white pvc resin paste grade powder stock is joined in heating container, and heating container temperature remains at 80-180 ℃, and be 30-80 minutes heat-up time.How many heat-up time and Heating temperatures are controlled with outside natural temperature and white raw material moisture.In this process, white powder raw material becomes gradually redness and powder and gradually becomes block;
3. naturally cooling: variable color and become block material to take out naturally cooling from heating container, be cooled to natural temperature.Be cooled to that red color after natural temperature deepens, block red pvc resin paste grade hardening;
4. grind: it is 100-500 object finished products that block red pvc resin paste grade is ground to fineness.
white pvc resin paste grade powder stock described in aforesaid method process steps 2 is the general product in market, and Ke You pvc resin paste grade manufacturer buys.
natural temperature described in aforesaid method process steps 3 is the temperature in natural air.
red pvc resin paste grade of the present invention has the following advantages: 1) by heating, remove or reduced the objectionable impurities of white pvc resin paste grade raw material the inside, make product safety and environmental protection more; 2) in making plastic product process, reduced temperature requiredly, reduced heat-up time, enterprise energy consumption reduces, and has improved production efficiency, has reduced production cost, thereby allow, uses enterprise to improve the standard of energy-conserving and environment-protective; 3) moisture content reduces, and solvability increases, and absorptivity improves, and sticks with paste viscosity and becomes large, and hardness uprises; 4) this paste resin is the substitute that resin is stuck with paste by Sweden 737, and resin cheap 30-40% per ton sticks with paste in cost ratio Sweden 737.

accompanying drawing explanation:
fig. 1 is production technique figure of the present invention
Embodiment:
specific embodiment of the invention method below:
1. preheating heating container: container needs preheating before putting into raw material, makes internal tank preheating temperature to 80 ℃;
2. thermostatically heating: white pvc resin paste grade powder stock is joined in heating container, and heating container temperature remains at 100 ℃, and be 60 minutes heat-up time.How many heat-up time and Heating temperatures are controlled with outside natural temperature and white raw material moisture.In this process, white powder raw material becomes gradually redness and powder and gradually becomes block;
3. naturally cooling: variable color and become block material to take out naturally cooling from heating container, be cooled to natural temperature.Be cooled to that red color after natural temperature deepens, block red pvc resin paste grade hardening;
4. grind: it is 100-500 object finished products that block red pvc resin paste grade is ground to fineness.
natural temperature described in aforesaid method process steps 3 is the temperature in natural air.
?
below novel red pvc resin paste grade of the present invention and white pvc resin paste grade parameter comparison:
red pvc resin paste grade/white the pvc resin paste grade of proterties
water content≤10/100
oil-absorption(number)>=335/100
stick with paste viscosity>=130/100
setting time≤(30 ~ 50)/100
anti-permeability>=115/100
as seen from the above table
water content: red pvc resin paste grade reduces more than 90% than white pvc resin paste grade;
oil-absorption(number): red pvc resin paste grade improves more than 335% than white pvc resin paste grade;
stick with paste viscosity: red pvc resin paste grade improves more than 30% than white pvc resin paste grade;
setting time: more than red pvc resin paste grade shortens 30%-50% than white pvc resin paste grade;
anti-permeability: red pvc resin paste grade improves more than 15% than white pvc resin paste grade.
