Abstract
The invention discloses a PVC material and a preparation method thereof. The PVC material comprises the following substances according to parts by weight: 100 parts of PVC, 2-8 parts of stabilizer, 2-6 parts of processing agent, 1.5-2.5 parts of lubricants, 4-12 parts of filler, and 0.05-1 part of colorant. Compared with the prior art, the invention adopts food sanitation-level or nontoxic raw materials; the mobility of the manufactured material is good, and the molding temperature and molding pressure of tubular products and pipe fittings can be reduced, thus preventing the PVC material from pyrolyzing. The PVC-U water supply tubular products, pipe fittings and pressure-proof ball valves made from the material have good acid and alkali resistance, inoxidability and ageing resistance, and the pressure resistance of the pressure-proof ball valve is more than or equal to 2.5MPa (the pressure resistance of similar products is only more than 1.6MPa), thus fully meeting food and chemical use requirements.
Description
Technical field
The invention belongs to PVC material and preparation method thereof, belong to foodstuff sanitation-stage hard PVC material and preparation method thereof especially.
Background technology
The water-feeding pipes in the market and the material of pipe fitting are generally cast iron pipe and galvanized pipe, the oxidation-resistance and the resistance to acids and bases of tubing and pipe fitting are poor, very easily water and other liquid are caused secondary pollution, and energy consumption is big, raw materials cost is high in making and also more complicated of the recycling of waste and old product, (PVC-U) replaces cast iron and zinc-plating material becomes a kind of new trend, but there is resistance to acids and bases, oxidation-resistance and the resistance to deterioration difference of the easy thermolysis of material and mobile poor, made tubing and part for the foodstuff sanitation-stage hard PVC material.
Summary of the invention
Technical problem to be solved by this invention provides the hard PVC material of a kind of heat resistanceheat resistant decomposition and good fluidity.
Another one technical problem to be solved by this invention is above-mentioned PVC preparation methods.
A kind of PVC material comprises following material and weight part:
PVC 100
Stablizer 2-8
Processing aid 2-6
Lubricant 1.5-2.5
Filler 4-12
Tinting material 0.05-1.
Described stablizer is organotin stabilizer, calcium stearate, epoxy soybean oil is a kind of or several mixture.
Described processing aid is the mixture of chlorinatedpolyethylene, CALCIUM ACRYLATE.
The model of described CALCIUM ACRYLATE is ACR401, is produced by Shandong RiKe Chemical Co., Ltd.
Decompose and mobile for the heat resistanceheat resistant of Reinforced PVC-U material, also add calcium-zinc composite stabilizing agent, the weight ratio of itself and PVC is 100:1.5～2.
Described lubricant is the mixture of stearic acid, paraffin, PE wax.
Described filler is a calcene.
Described tinting material is diamond-type titanium dioxide and sooty mixture.
Preparation method of the present invention is: is that 110-115 ℃, rotating speed are under the situation of 400r/min-500r/min with PVC raw material and organotin stabilizer, calcium stearate, processing aid in temperature, stirred 10-15 minutes, stop to stir, add remaining raw material again, in temperature is that 110-115 ℃, rotating speed are under the situation of 500r/min-600r/min, stirs 20-25 minutes, and rotating speed is reduced to 100r/min-150r/min, be cooled to 45-55 ℃, discharging.
Prepared PVC material can carry out the granulation injection moulding or squeeze pipe through tapered twin screw plastics extruder, forms tubing or pipe fitting, big ring flange.
Because the PVC of foodstuff sanitation-stage can not use the lead salts stablizer, thereby the present invention selects nontoxic organotin, epoxy soybean oil, calcium stearate, calcium-zinc composite stabilizing agent as stablizer, epoxy soybean oil not only has function of stabilizer, also have good low temperature plasticity, good heat-resisting, light fastness, also to colorant stir, homodisperse and paintedly all have very great help in the production of articles, calcium stearate not only has preferably stability, and with the shared stabilising effect that improves of epoxy soybean oil.
ACR401 in the processing aid of the present invention (polyacrylate) can reduce mold temperature, shortens the fusion time, reduces the processing units scale formation, improves low-temperature impact resistance, profile pattern, smooth finish and the ageing-resistant performance of tubing.
Lubricant of the present invention is the mixture of stearic acid, PE wax and solid paraffin, and it is an amount of that the add-on of lubricant is wanted, and when it was excessive, pvc pipe material surface will " frosting " and the generation weld mark.
Filler of the present invention is a calcene, except that reducing raw materials cost, can also improve the size of goods and the stability of tone.Because made water-feeding pipes is to stretch two-way (vertically, laterally) in moulding, to the toughness reguirements height of material, so the consumption of filler is subjected to very big placing restrictions in the prescription.
Tinting material of the present invention is Rutile type Titanium Dioxide, carbon black, is good photomask agent, and oxidation-resistance, resistance to deterioration and the chemical stability of PVC played fine effect.
The stablizer of PVC of the present invention is selected non-toxic organic tin and non-lead salts stablizer (being calcium stearate, epoxy soybean oil, calcium-zinc composite stabilizing agent etc.) for use; Processing aid is selected nontoxic ACR for use; Lubricant is the solid mountain tallow of used for packing foods and nontoxic PE wax; Weighting agent is nontoxic calcene; Tinting material is some harmless titanium dioxides, carbon black; Above-mentioned raw materials all is to meet the raw material of state food health with standard.
The present invention is by the common use of epoxy soybean oil, acrylics (ACR401), calcium stearate and organotin stabilizer, produced collaborative preferably answering, the mold temperature of tubing and pipe fitting is reduced, the extrusion temperature of tubing is reduced to about 170 ℃ from 200 ℃, injection pressure descends, and the production efficiency when extruding improves; The fouling situation of screw rod obviously reduces.The mold temperature of injection moulding pipe fitting is reduced to about 180 ℃ from 210 ℃, prevents the thermolysis of PVC material.
The present invention compared with prior art, used raw material all adopts foodstuff sanitation-stage raw material or poisonous material, made material flowability is good, can reduce mold temperature, the forming pressure of tubing and pipe fitting, prevent the thermolysis of PVC material, resistance to acids and bases, oxidation-resistance and resistance to deterioration with PVC-U water-feeding pipes, pipe fitting and the withstand voltage ball valve of this material produce are good, resistance to pressure 〉=the 2.5MPa of withstand voltage ball valve (resistance to pressure of analogous products is only〉1.6MPa), meet the service requirements of food, chemical industry fully.
