Description
Technical field
The present invention relates to chemical building material field, be specifically related to colored hardboard of a kind of pvc and preparation method thereof.
Background technology
Phosphogypsum Shi Lin compound fertilizer enterprise with phosphorus ore and sulfuric acid for major industry by product during raw material production phosphoric acid, wet method phosphoric acid manufacture process is all produce extraction slurry by sulfuric acid decomposition ground phosphate rock, then filter obtained phosphoric acid, in the process of filtration washing, produce phosphogypsum waste.Along with the industry of phosphorus ammonium and the development of high-concentration phosphate compound fertilizers, the quantity discharged of phosphogypsum increases year by year, and the whole world increases phosphogypsum quantity discharged every year newly and reaches 2.8 hundred million tons at present, and about 5,000 ten thousand tons, China, accounts for 20% of world's phosphogypsum annual emissions.A large amount of phosphogypsums is stacked, not only land occupation resource, tremendous economic burden is increased to enterprise, but also certain pollution can be caused to environment, China's phosphogypsum is not applied very well for a long time, and utilization ratio is only 10%, year utilization be only 400-500 ten thousand tons, the emission problem of phosphogypsum has become the important factor of restriction production of phosphate fertilizer, and the phosphogypsum comprehensive utilization technique developing a kind of practicality has great importance.
Therefore the present invention solves phosphogypsum stacking to cause the problem of the wasting of resources and environmental pollution to propose colored hardboard of a kind of pvc and preparation method thereof.
Summary of the invention
For solving the problems of the technologies described above, the invention provides colored hardboard of a kind of pvc and preparation method thereof.
The present invention is achieved by the following technical programs:
The colored hardboard of a kind of pvc, it is made up of following raw material: pvc resin 120-140 part, stablizer 4-10 part, internal lubricant 0.6-1.2 part, properties-correcting agent 0.5-1.1 part, filler 31-39 part, external lubricant 0.8-1.4 part.
The colored hardboard of described pvc is made up of following raw material: pvc resin 125-135 part, stablizer 6-8 part, internal lubricant 0.8-1 part, properties-correcting agent 0.7-0.9 part, filler 34-36 part, external lubricant 1-1.2 part.
The colored hardboard of described pvc is made up of following raw material: pvc resin 130 parts, stablizer 7 parts, internal lubricant 0.9 part, properties-correcting agent 0.8 part, filler 35 parts, external lubricant 1.1 parts.
Described stablizer is the mixture in tribasic lead sulfate, two basic lead sulfites, lead stearate.
In described stablizer, the blending ratio of tribasic lead sulfate, two basic lead sulfites, lead stearate is 2:1:1.
Described internal lubricant is polyethylene wax.
Described external lubricant is the one in stearic acid, butyl stearate, oleylamide.
Also containing titanium dioxide 0.5 part in the raw material of the colored hardboard of described pvc.
Present invention also offers the preparation method of the colored hardboard of above-mentioned pvc, the method comprises the following steps:
A, filler: after phosphoric acid cream being crossed respectively 200 orders, 250 orders, 300 object sieves, carry out difference calcination processing again, calcination processing is by the temperature lower calcination 90min of the phosphogypsum of mistake 200 mesh sieves at 200 DEG C respectively, the phosphogypsum crossing 250 mesh sieves is at the temperature lower calcination 90min of 300 DEG C, the phosphogypsum crossing 300 mesh sieves is at the temperature lower calcination 90min of 400 DEG C, finally grind 70min by putting into spherical grinder after the phosphogypsum of calcination processing respectively mixes again, being milled to surface-area is 290m
2/ kg obtains filler;
B, batch mixing: stir when pvc resin is added in high-speed mixer and be warming up to 70 DEG C, continue when adding stablizer to be warming up to 100 DEG C, continue when dropping into lubricant to be again warming up to 120 DEG C, finally enter in cold mixer cold mix to 50 DEG C can discharging for subsequent use, mixing time is 30min, and the order of reinforced combination treatment is followed successively by pvc resin, stablizer, internal lubricant, properties-correcting agent, filler, titanium dioxide, external lubricant;
C, shaping: the control of mold temperature is that the barrel temperature of single screw extrusion machine controls to be 160 DEG C, and twin-screw extruder barrel temperature 170 DEG C, linear extrusion speed are 1.2m/min, finally by cooling and shaping process.
Beneficial effect of the present invention is: have excellent chemical stability by a process for preparing the colored hardboard of the pvc come, erosion resistance, hardness is large, strengthening degree is high, ageing-resistant, do not absorb water, indeformable, mixed degree evenly, easy processing, the feature that production efficiency is high, with the addition of in the processing raw material of sheet material by screening, calcining, grind the filler be prepared from, raising timber intensity can be played, the effect of hardness, because filler is obtained by processing phosphogypsum, not only serve the effect promoting board quality, but also solve the problem that the stacking of a large amount of phosphogypsum causes environmental pollution.
