Description
Technical field
The invention belongs to building material field, relate in particular to a kind of resource-conserving ash and mould the foaming macromolecular matrix material.The invention still further relates to the preparation method of above-mentioned matrix material.
Background technology
Flyash is the maximum single emission source of China's industrial solid wastes.For many years, the flyash of domestic each large, medium and small type heat power plant is not all efficiently utilized, and traditional in the past storage, disposal options such as buries, and environment has been caused havoc, and public health has been brought very big harm.China's flyash mainly is used for producing the product that concrete, coal-dust brick, cement etc. are with low content of technology, added value is low at present, and utilization ratio and utilising efficiency are lower.The someone has invented " a kind of prescription of environment-friendly ceramic polymer composite material and preparation method " recently.Utilize thermoplastics PE, PVC and flyash to mix, through section bars such as hot-extrudable explained hereafter floors, though this product has improved utilization of coal ash value relatively, product is than great, and cost is high, and range of application is little, and the marketing utilization is difficulty very.And technological method and technology thinking that the present invention proposes; Polymer composite with high powder filler coal ash and polyvinylchloride foaming preparation; Not only substituted calcium fully and moulded the traditional product with Wood-plastic foam, flyash has been carried out to greatest extent resource utilization recycle, and improved the flame retardant resistance and the physicals of product; Added value is higher, and purposes is wider.This polymer composite can extensively apply to building and ornament materials, floor, building template, fields such as landscape gardening, furniture.Have that cost is low, in light weight, intensity is high, advantage such as corrosion resistant, high-low temperature resistant, flame retardant properties are good, not yielding.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical defective, provide a kind of resource-conserving ash to mould foaming macromolecular matrix material and preparation method thereof.
According to thermoplastics polyvinylchloride, the good fluidity and the cohesiveness that under melt temperature, are had; Powdery after the modification or granular material carry out melting foaming extrusioning shaping to be handled; This chemical building material belongs to the polymer composite of novel environment friendly; Stable chemical performance, the type material of nontoxic, tasteless, acidproof, alkaline-resisting, high-low temperature resistant and light specific gravity, good flame resistance.
Technical scheme of the present invention is: a kind of resource-conserving ash is moulded the foaming macromolecular matrix material, comprises thermoplastics PVC, weighting agent flyash, auxiliary heat stabilizer, coupling agent, one package stabilizer, inside and outside lubricant agent, plasticizing promotor, general whipping agent, foaming control agent.
A kind of resource-conserving ash is moulded the foaming macromolecular matrix material, is made up of following component by weight: 10～99 parts of thermoplastics polyvinylchlorides, 1～90 part in weighting agent flyash 200-3000 order, 0.5～3 part of auxiliary heat stabilizer, 0.5～3 part of coupling agent, 1～5 part of one package stabilizer, 0.5～3 part of inside and outside lubricant agent, 1～5 part of promotor of plasticizing, 0.5～3 part of general whipping agent, 0.5～3 part of foaming control agent.
Thermoplastics is a polyvinylchloride.
Weighting agent is a flyash.
Auxiliary heat stabilizer is an epoxy soybean oil.
Inside and outside lubricant agent comprises one or more mixtures of Zinc Stearate, hard ester acid, calcium stearate, polyethylene wax or paraffin.
Coupling agent is aluminate coupling agent or silane coupling agent.
Plasticizing promotor is a kind of of ACR530-201 or ACR530-301.
General whipping agent is a kind of of composite foamable agent C-2 or UC200.
Foaming control agent comprises a kind of of foaming control agent HL175S or foamed promoter zinc oxide.
One package stabilizer is a calcium zinc stabilizer.
A kind of resource-conserving ash is moulded the preparation method of foaming macromolecular matrix material, and concrete steps are:
(1), prepares raw material by above-mentioned weight part proportioning;
(2), flyash is put into high mixer 120 degree high temperature and dehydrate processing.
(3), coupling agent, inside and outside lubricant agent are put into high mixer and bulking agent carries out thorough mixing, flyash being carried out coating modification, is 3～5 minutes in 120 ℃ of mixing times;
(4), with thermoplastics PVC put into high mixer and one package stabilizer, plasticizing promotor thorough mixing coats, and will coat good powder, general whipping agent, foaming control agent after the shutdown in 120 ℃ of mixing 3 minutes that run up; (5), at last put into auxiliary heat stabilizer and all materials in 120 ℃ of following thorough mixing 2 minutes, get final product discharging below being cooled to 50 degree.
This
The beneficial effect of the invention is:Flyash is carried out the high added value recycling, can not only practice thrift a large amount of lime carbonate and timber resources, and reduce environmental pollution, the protection human health.Characteristics of the present invention: with at the bottom of general Wood-plastic foam material is compared weathering resistance, good flame resistance, water-intake rate, waterproof, mildew-resistant, physics, the chemical property of making all kinds of section bars are more stable, intensity is higher.Mould foam material with general calcium and compare, light specific gravity, cost low
; About 800-1200 yuan/tons of light calcium carbonate and wood powder market price, flyash is zeroth order almost, has improved the competitiveness of product in market.Replace wholly or in part that existing calcium is moulded, Wood-plastic profiles and log.Can produce architectural decoration material, materials for wall, floor, household, industrial pallet, building template, etc. product.Make section bar with polymer composite of the present invention, extrude stable processing technique, temperature is regulated easily; Material can not produce the charing phenomenon.This material and have regeneration character, scrap stock or discontinued product can through reclaim, extrusion profile product again after the fragmentation.Because fly ash grain is thin, be manufactured into various section bars intensity height in light weight though ash is moulded the foaming macromolecular matrix material, and cost is low, economic value added is high, also can be widely used in related industries fields such as municipal administration, gardens construction, building materials, various tubing.Social benefit and environment protection significance that this invention had are obvious, meet the thinking of development of country's " resource-conserving, environmentally friendly ", for country's " energy-saving and emission-reduction ", " developing a circular economy " have Special Significance.
At present, the standard that ash is moulded the implementation of foaming macromolecular matrix material is a company standard, and product is through detecting, and partial data is following:
