Abstract
A die pressing technology for making the composite products uses the waste or used polypropylene, polyethylene, polyester, polyvinyl chloride, and polystyrene, and powdered coal ash from steam-power plant as raw materials and includes sieving said powdered coal ash by so meshes, selecting assistant and die pressing. Said products feature high compression strength, bending strength, bending modulus, elongation at break and tension strength, and high service temp raised by 10 deg.C.
Description
The present invention is the die press method for producing that belongs to waste or used plastics and flyash composite product.Flyash and waste or used plastics are the wastes of serious environment pollution, utilize these wastes to develop high attached value product in a large number, make it to reduce to pollute, turn waste into wealth, and resource recovery, this is a resource reutilization engineering with economic benefit and environmental benefit.
Chinese patent " 97101791.3 " discloses the invention that is entitled as " production method that flyash is made well lid ", this patent only relates to the method for flyash system well lid, and the granularity requirements of used flyash is not less than 200 orders in the patent, and its composition stipulated scope, utilization of coal ash is restricted.This invention work in-process does not sort multiple plastics, and only adds a kind of auxiliary agent, and how anti-aging, the anti-illumination of goods, shock resistance etc. are not added with the relevant auxiliary agent of this respect, so these performances of goods are difficult to guarantee.Because different plastics have different properties, differ greatly as fusing point, Fen Jian plastics work in-process certainly will not cause being separated of storeroom, even the composition that has degrades, thereby greatly influences product properties.
The die press method for producing that the purpose of this invention is to provide a kind of waste or used plastics and flyash composite product.This method is that application waste or used plastics and flyash are main raw material, and preparation well lid, well grate, tree pond grate, Slope protection plate, wall dunnage, Road isolating pillar can replace metal products, cement metal stiffening web goods and plank goods.
The present invention is by adding multiple auxiliarys such as a spot of surface treatment agent, toughner, coupling agent, protective agent, softening agent, synergistic effect and the online reaction processing of utilization in kneading and extrusion, improve the cohesiveness of two-phase interface and increase-volume, plasticising, toughness reinforcing, erosion-resisting characteristics, improved alternate consistency and flyash dispersed uniform in plastics.
Waste and old polypropylene (PP), polyethylene (PE), polyester (PET), polyvinyl chloride (PVC) and the polystyrene (PS) that the present invention adopts is with preceding drying, pulverizing, granulation; Thermal power plant's electrostatic precipitation flyash ablation amount＜10%, screening＜80 orders.Concrete proportioning (parts by weight) is: with flyash 30-300 part and silane coupling agent 3-5 part, mediated 5 minutes down at 70-90 ℃, the flyash after will handling then carries out drying and removes moisture; Waste or used plastics PP or PE or PET or PVC or 100 parts of PS and waste Crumb rubber 5-30 part with granulation, ethylene 5-10 part, anion surfactant 1-5 part, acrylate 0.5-2 part, stearic acid 0.5-3 part, 3 parts of barium stearates, paraffin wax 5-10 part, oxidation inhibitor 0.2-1.0 part, antimonous oxide+decabromodiphenyl oxide 5-10 part, SULPHUR POWDER 1-5 part, Cellmic C 121 8-12 part, zinc oxide+tris phosphite 0.1-0.4 part, go to select required component in the auxiliary agent according to different goods, after mediating 10 minutes under the 80-120 ℃ of condition, this material and flyash were after treatment mediated 10 minutes under 80-120 ℃ of condition, the forcing machine of this material being put into 130-200 ℃ is extruded again, the material of extruding is put into mould, on the pressing machine of 250-500 ton, kept 15-25 minute, compression molding, demolding after cooling.
The prepared product ultimate compression strength of the present invention can reach 24-36MPa, bending strength 18-28MPa, and composite bending modulus 400-1200MPa, elongation at break 5-18%, tensile strength 13-25MPa, oxygen index 〉=27, use temperature is compared with former waste or used plastics and is improved more than 10 ℃.
The present invention makes full use of general waste or used plastics: PP, PE, PVC, PET, PS, and improves the waste Crumb rubber that impact property adopts; Flyash content can be up to 3 times of plastic content, and its granularity gets final product at≤80 orders, made well lid, and the well grate, tree pond grate is without any need for metal or nonmetallic liner skeleton.Add an amount of oxidation inhibitor, photostabilizer for prolonging product life, interior trim microvesicle wall dunnage is then added fire retardant and whipping agent.
