Abstract
The invention discloses a PVC profile produced by taking phosphogypsum as filler. The PVC profile is prepared from the following raw materials in parts by weight: 130-150 parts of PVC (polyvinyl chloride) resin, 6-12 parts of stabilizer, 0.6-1 part of lubricant, 1-5 parts of fire retardant, 30-36 parts of filler and 0.3-0.7 part of coloring agent. According to the PVC profile produced by taking the phosphogypsum as the filler, the phosphogypsum is screened to reduce the content of impurities; the screened phosphogypsum is calcinated to further remove the impurities and improve the whiteness; the calcinated phosphogypsum is ground to be modified, so that the size distribution is adjusted; the finally processed phosphogypsum is taken as the PVC filler, and then the strength and the hardness of the prepared PVC profile are improved largely; furthermore, the produced PVC profile has the characteristics of aging resistance and corrosion resistance; the production costs of the profile are low, a problem that the phosphogypsum is stacked to cause environment pollution is solved, a purpose of reutilizing the phosphogypsum source is achieved, and the economic benefit is improved.
Description
Technical field
The present invention relates to chemical building material field, be specifically related to a kind of pvc section bar taking phosphogypsum as filler and produce.
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 is only 400-500 ten thousand tons, the emission problem of phosphogypsum has become the important factor of restriction production of phosphate fertilizer, and therefore, the phosphogypsum comprehensive utilization technique developing a kind of practicality has great importance.
The product category that PVC material makes is more, as PVC, PVC profile, PVC board etc.And in the production process of PVC material, its needs add filler, stablizer, lubricant and other additives among raw material; Traditional PVC produces the filler adopted and has related generally to calcium stearate, calcium carbonate etc.
In order to improve the quality of pvc section bar and solve the problem of phosphogypsum resource reutilization, the present inventor is the pvc section bar that filler is produced by researching and proposing a kind of with phosphogypsum.
