Abstract
The invention discloses an improvement method of a polyvinyl chloride paste resin. The improvement method can reduce the water content in the original polyvinyl chloride paste resin, and decreases the required temperature and heating time in the product preparation process, thereby lowering the energy consumption of the enterprise for producing the polyvinyl chloride paste resin by using the improvement method, enhancing the production efficiency, lowering the production cost, and further enhancing the energy-saving environment-friendly standard of the enterprise. The method comprises the following steps: preheating a heating container; heating at constant temperature; naturally cooling; and grinding and the like.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of modification method of 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 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, makes PVC thickener, makes thickener gelation, then after cooling, can make plastic product by heating, and prior art is used for being processed into final plastics with this form exactly.
the pvc resin paste grade circulating on the market now temperature required height of heating in being processed into the heat-processed of plastic product, heat-up time is long, allows and uses enterprise energy consumption to increase, and has reduced production efficiency, improve production cost, thereby allow, used 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 modification method of pvc resin paste grade is disclosed, the pvc resin paste grade obtaining by modification method of the present invention not only can reduce the moisture of former pvc resin paste grade, also in making product process, reduced temperature required, reduce heat-up time, allow and use the enterprise energy consumption of the pvc resin paste grade that modification method of the present invention obtains to reduce, improved production efficiency, reduce production cost, thereby allow, used enterprise to improve the standard of energy-conserving and environment-protective.
in order to achieve the above object, the technical scheme steps of using 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 100-2000 object finished products (can change order number according to customer need) 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.
the method of the invention makes product and has the following advantages: 1) by heating, remove a large amount of pvc resin paste grade raw materials the inside excessive moisture; 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) significantly improved oil-absorption(number), solvability increases, and absorptivity improves, and sticks with paste viscosity and becomes large, and toughness improves greatly; 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 45-60 minute 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 100-2000 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 to make red pvc resin paste grade and white pvc resin paste grade parameter comparison is buied in market by the method for the invention:
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.
