Strengthening flexibilizer is PMMA modifier, has excellent low-temperature flexibility and ageing resistace, and PVC is had the toughness reinforcing and weather-proof effect of significant enhancing, and the PVC goods after the modification can still have fine toughness under-20 ℃, improved the scope of application of product.
CPE introduces a kind of toughness high molecular polymer that the chlorine atom obtains on the sub polyethylene subchain, be the good flexibilizer of PVC.
Rice husk aboundresources, rice husk are rich in cellulose, lignin, silica, and the application of rice husk in plastic processing more and more widely need be carried out preliminary treatment before the powdered rice hulls use, and concrete steps are as follows:
1, powdered rice hulls descended dry 3-3.5 hour at 150 ℃; 2, dry powdered rice hulls is joined in the homogenizer, warming while stirring to 90 ℃, add inorganic modified dose of nano-calcium carbonate and organic modifiers monoalkyl fatty acid ester coupling agent, it is powdered rice hulls by weight: nano-calcium carbonate: coupling agent=100:2:1, stir 10-20min, discharging in the time of 100 ℃, powdered rice hulls adopts inorganic and organically-modified respectively, the inorganic modified hear resistance that improves powdered rice hulls, for extruding processing wideer processing temperature scope is provided with PVC is compound, reduced in the raw material organic acid simultaneously to the corrosion of equipment, and the organically-modified powdered rice hulls surface hydroxyl that reduced, reduce the water imbibition of powdered rice hulls, increased the compatibility of powdered rice hulls and PVC.
The preparation method of composite plastic template of the present invention is:
1, high low temperature stirs, and (1), in the mixer that rotates is added to the PVC powder in the mixing machine; (2), at 60 ℃, heat stabilizer is joined heat mixes in the machine, guarantee material stability in the heat temperature raising process; (3), in the time of 80 ℃, processing aid, lubricant, function additive are added to heat mix in the machine, make auxiliary agent be distributed in the PVC molecular surface effectively; (4), in the time of 100 ℃, precipitated calcium carbonate and modification powdered rice hulls are added to heat mix in the machine, even parcel PVC molecule under the effect of lubricant; (5), at 110 ℃～130 ℃, blowing agent and foaming control agent are added to heat mix in the machine, mix 12～15min; (6), afterwards,, rotate down and discharge material, send into mixed on low speed 20～25min in the cold mixer at 115 ℃～130 ℃; (7), in the time of 40 ℃～50 ℃, discharge material, sieving for standby.
2, co-extrusion foaming moulding, extruder screw divides 3 sections: feeding section, fusing section, homogenizing zone, these three sections corresponding materials have been formed 3 functional areas: solid conveying zone, material plasticizing district, melt Conveying district, the barrel temperature of solid conveying zone is controlled at 100～140 ℃, if charge temperature is low excessively, solid conveying zone is prolonged, reduced the time in plasticizing zone and melt Conveying district, can cause plasticizing uneven, influence product quality;
The temperature in material plasticizing district is controlled at 165～185 ℃; The temperature in melt Conveying district is 160～180 ℃, and screw speed is controlled at 20～30r/min; Enter foaming mould at last and foam, mould is heated and is adopted the heating of stainless steel electrically heated rod, and the uniform and stable property of discharging is good, adjusts the thickness of blanket by die lip.
3, cooling and shaping, the blanket of extruding from machine head port mould will carry out cooling processing through cooling calibrator, make its hardening and finalize the design, adopt water cooling mode, products temperature is reduced to below 50 ℃, in the cooling procedure blanket is vacuumized processing, the blanket in the cooling processing transmits by the cooling conveying-bridge.
4, cutting edge is vertically cut edge and cutting device carries out the cutting edge processing to the blanket on the cooling conveying-bridge.
5, traction, the effect of draw-gear is to provide certain tractive force and hauling speed to the sheet material that head is extruded, and draws template equably, and by regulating the thickness of hauling speed control template; Hauling speed depends on extruded velocity, and general hauling speed is than extruded velocity fast 1%～3%.
6, cutting, cutter sweep is realized the vertical and horizontal fixed length sawed-off (can set the sawed-off length of sheet material) of goods, guarantees that cuts sheet material is the right angle, length and width reaches the requirement of setting.
7, windrow, finished product packing.
Composite plastic template of the present invention, be to form by PVC plastics and the compound extrusion foaming of rice hull cellulose, the advantage of plastics and rice hull cellulose is organically combined, hydrophobicity and anti-flammability that existing PVC plastics are good, the high strength and the processing diversity that have kept bamboo and woods fiber again, composite plastic template is from heavy and light, and good processability can be followed closely, digs, saws, cut; The physical and mechanical property excellence has characteristics such as high-strength, high-ductility, high rigidity; Template surface is smooth, need not releasing agent, and is environment friendly and pollution-free, and stripping result is good, can do the clear water metope; Template waterproof, protection against the tide, water absorption rate are low, have fundamentally solved problems such as wooden template product suction back is perishable, expansion, distortion; The template weatherability is good, good flame retardation effect, and it is fire-retardant to reach the B1 level.
