Abstract
The invention discloses a producing method for thermal insulated and damping materials using vehicle top coat residues including: the residues are collected, washed by softener, dried, crushed into powder, mixed together, which involves 10-20 shares of asphalt, 30-40 calcium carbonate powder, 30-40 residues and 5-10 calcium chloride, then milled in the double-roller machine, compressed to slices, and pressed to the form. The advantages of this invention is that the thermal insulated and damping materials for motors are made from top coat residues which is mainly from high-grade polyacrylic resin, so that its decay resistance, heat resistance and other properties are improved while the cost is decreased.
Description
Technical field
The present invention relates to a kind of manufacture method of heat-insulating damp material, especially a kind of method of utilizing automobile finish waste to make heat-insulating damp material.
Background technology
Automobile plant is when spray paint, and coating cloud discharges in a organized way, and with water sepn lacquering slag, burning will cause secondary pollution, for environment protection does not allow after water cycle is pounced on collection, flocculation; The useless solid center processing of cross ring guarantor department, expense is higher; Take to bury with contaminated land or underground water.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing automobile finish waste to make heat-insulating damp material, this a kind of method will be coated with lacquer and will be used to prepare the automobile industry heat-insulating damp material after slag is reclaimed, and better solve the problem of outlet of lacquer slag.
Technical scheme of the present invention is: a kind of method of utilizing automobile finish waste to make heat-insulating damp material, and its step: the coating cloud that (1) produces when collecting automobile plant's spray paint discharges in a organized way, after recirculated water is pounced on collection, flocculation and water sepn lacquering slag; (2) clean, be neutralized to PH7-7.5 through soft water, remove most of water with filter press again with diluted acid; (3) again in rotary vacuum drier in 600-120 ℃ of temperature range, under 720-740mmHg post vacuum dry 4-8 hour; (4) dry lacquer slag is through pulverizing the lacquering ground-slag; (5) following material was put into twin-screw mixing procedure machine batch mixing 1-2 hour by weight proportioning: pitch 10-20 part, Paris white 30-40 part, lacquer ground-slag 30-40 part, calcium chloride 5-10 part; (6) then on twin-screw extruder mixing evenly, be pressed into thin slice; (7) use artificial or mechanical compression molding again, packing promptly becomes product through being up to the standards.
The invention has the advantages that: with the automobile heat-insulating damp material that the lacquer slag is made, because the lacquer slag mainly is made up of high-grade polyacrylic resin, performances such as its rotproofness, thermotolerance all increase, and cost then decreases.
Embodiment
The technical scheme block diagram is as follows: lacquer slag → cleaning → neutralization → press filtration → vacuum-drying → pulverizing → batch mixing → refining → moulding → check → finished product → packing.
Technical scheme is described below: the coating cloud that produces during the automobile plant spray paint discharges in a organized way, pounce on collection, flocculation back and water sepn lacquering slag through recirculated water, clean, be neutralized to PH7-7.5 through soft water with diluted acid, remove most of water with filter press again, again in rotary vacuum drier in 600-120 ℃ of temperature range, under 720-740mmhg post vacuum dry 4-8 hour, dry lacquer slag was through being ground into the lacquer ground-slag of certain order number.The prescription of heat-insulating damp material: 15 kilograms of pitches, 35 kilograms of Paris whites, 40 kilograms of ground-slags of lacquer, 7 kilograms in calcium chloride, the weighing of filling a prescription in accordance with regulations of above-mentioned component, put into twin-screw mixing procedure machine batch mixing 1-2 hour, mixingly on twin-screw extruder then meet the requirements to penetration degree, be pressed into thin slice, be pressed into desired shape and thickness with artificial or machinery again, packing promptly becomes product through being up to the standards.
The product salient features:
1, proportion g/cm
31.4 ± 0. 12, receive liquid rate %≤3
3, falling into property mm 〉=84, mobile mm≤15
5, resistance to sudden cooling-20 a ℃ cracking peel off 6, shearing resistance Mpa 〉=0.49
7, steam output %≤0.6 8, hot melting temperature ℃ 130 ± 5
9, damping factor tga 〉=0.3
