After the PVC section bar is prepared by mixing the phosphogypsum, PVC, titanium dioxide, a composite stabilizer and a lubricant in proportion, the phosphogypsum is used for replacing calcium powder in the preparation process of a conventional PVC section bar, so that the source of calcium powder for PVC is expanded, the cost of the calcium powder for PVC production is reduced, the stock amount of the phosphogypsum is reduced, the comprehensive utilization way of the phosphogypsum is expanded, and the comprehensive utilization rate of the phosphogypsum is improved.
Description
Technical field
The present invention relates to pvc pipe production technical field, the PVC profile that especially a kind of phosphogypsum is produced as filler and production method thereof.
Background technology
Along with the research to PVC material, the properties of PVC material obtains and significantly improves, and makes PVC material obtain large-scale application, and 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.
Phosphogypsum is in industrial phosphoric acid production process, the trade waste produced when adopting Wet-process Phosphoric Acid Production method to produce phosphoric acid, its main component is terra alba, since 2010, phosphogypsum year, generation reached 4000-7000 ten thousand tons, and be not well used for a long time, make the volume of cargo in storage of phosphogypsum larger; Therefore, there is a large amount of investigators to take to comprehensive utilizating research in phosphogypsum, and the raw material of phosphogypsum as material of construction is prepared, as insulation blocks etc.; Investigator is also had to it can be used as the raw material etc. preparing calcium oxide, sulfurous gas; However, be less than 10% to the comprehensive utilization ratio of phosphogypsum every year, the comprehensive utilization of phosphogypsum is developed also to be needed further to strengthen process.
Based on this, this investigator is the feature of calcium powder in conjunction with the filler adopted in PVC profile production process of the prior art, phosphogypsum is carried out proportion design as the raw material in PVC profile production process, and in conjunction with PVC profile production technique, for the comprehensive utilization of phosphogypsum brings new way.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the invention provides PVC profile and production method thereof that a kind of phosphogypsum produces as filler.
Be achieved particular by following technical scheme:
The PVC profile that phosphogypsum is produced as filler, it comprises material composition PVC90-110 part of following parts by weight, phosphogypsum 35-37 part, titanium dioxide 3-5 part, one package stabilizer 19-21 part, lubricant 1.5-2.3 part.
The described following parts by weight of the material composition comprised is PVC100 part, phosphogypsum 36 parts, titanium dioxide 4 parts, one package stabilizer 20 parts, lubricant 2 parts.
Described lubricant is the one in Zinic stearas, oleylamide, distearyl dimethyl ammonium chloride, sylvic acid, polydimethylsiloxane, stearic acid, PE wax.
The production method of the PVC profile that described phosphogypsum is produced as filler, comprises the following steps:
(1) PVC, phosphogypsum, titanium dioxide, one package stabilizer, lubricant raw material are mixed in high/low temperature mixing machine, first carry out high temperature mixing, mixing temperature is 120 DEG C, carry out low-temperature mixed again, mixing temperature is 50 DEG C, then is discharged by mixture, stand-by;
(2) step (1) described mixture is placed in twin screw extruder, adjustment electric current is 46A, extrusion screw rod rotating speed is 13.1r/min, and feed-screw rotating speed is 10.1r/min, and machine barrel one district temperature is 165 DEG C, machine barrel two district temperature is 167 DEG C, machine barrel three district temperature is 163 DEG C, and machine barrel four district temperature is 160 DEG C, and core temperature is 150 DEG C, die temperature is 188-200 DEG C, extrusion profile blank;
(3) cooling forming;
(4) pulling speed is 1.65m/min.
The PVC profile that described phosphogypsum is produced as filler, it is when being applied to material of construction and preparing, and its welding temperature is 170 DEG C.
Compared with prior art, technique effect of the present invention is embodied in:
After phosphogypsum and PVC, titanium dioxide, one package stabilizer, lubricant are mixed with PVC profile according to proportioning, it makes phosphogypsum instead of calcium powder in conventional P VC section bar preparation process, expand the source of PVC calcium powder, reduce the cost of PVC production calcium powder, reduce the volume of cargo in storage of phosphogypsum, expand phosphogypsum comprehensive Utilization Ways, improve phosphogypsum comprehensive utilization ratio.
Phosphogypsum and above-mentioned raw materials are carried out proportioning by the present invention, it is first carried out high temperature mixing in high/low temperature mixing machine, carry out low-temperature mixed again, phosphogypsum is made to obtain dry powder blend, and obtain dry mix, improve the mobility of phosphogypsum, and the plasticity-of phosphogypsum is improved, make phosphogypsum after mixing with raw material, its mixture obtained presents bean curd scoriform.
The present invention is by the proportion design of raw material and the state modulator of preparation technology and adjustment, especially the control of the parameter of extrusion, the stretch-proof of the PVC profile prepared is impacted more excellent, comparison with standard improves about 10%, falling weight impact test, it only only has 2 little breakages, and large face is without disrepair phenomenon.
PVC profile prepared by above-mentioned proportioning raw materials is also used for welding and is prepared into material of construction by this investigator, and the welding temperature in welding process is adjusted, and the fillet weld strength corresponding to relevant temperature is tested, it draws, when welding temperature is 145 DEG C, its fillet weld strength is 1475N, meets the standard being more than or equal to 1400N; When welding temperature is 150 DEG C, its fillet weld strength is 1485N, meets the standard being more than or equal to 1400N; When welding temperature is 160 DEG C, its welding strength is 1165N, does not meet the standard being more than or equal to 1400N; When welding temperature is 170 DEG C, its fillet weld strength is 1520N, meets the standard being more than or equal to 1400N; As can be seen here, this section bar is when carrying out being welded into material of construction, and the more excellent temperature of its welding is 170 DEG C, and can guarantee that fillet weld strength is more excellent.
