Abstract
The invention discloses a pretreatment recycling method of waste powder from polishing of an artificial stone. The method comprises the steps of firstly drying the waste powder from the polishing of the artificial stone, then using a treatment agent to carry out pretreatment on the waste powder from the polishing of the artificial stone, and further recycling the waste powder in the preparation of the resin type artificial stone, wherein the pretreatment is as follows: adding the treatment agent of the waste stone powder which accounts for 0.5-3% by weight of the waste powder from the polishing into the waste powder from the polishing, then stirring for 20-60min, and preparing the pretreated waste powder from the polishing of the artificial stone; the treatment agent of the waste stone powder comprises 60%-90% of triethanolamine, 2%-20% of stearic acid and 8%-30% of styrene according to the weight percent; and the treatment agent used in the pretreatment method has the advantages of wide sources of raw materials and low price, and the recycling of the waste powder in the preparation of the resin type artificial stone can lead the using amount of resin to be not more than 10%, and lead the surface to be smooth and flat and have no defects. The pretreatment can not only reduce the powder agglomeration and be conductive to dispersion, but also improve the bonding capacity between powder and the resin, and improve the bending strength by more than 20% in comparison with a product without carrying out the pretreatment.
Description
Technical field
The present invention relates to the technical field of utilizing of the useless powder of rostone polishing, be specifically related to a kind of useless powder of pre-treatment rostone polishing that utilizes, to prepare the method for rostone.
Background technology
Rostone is meant with the unsaturated polyester to be binding agent, adds aggregate and other admixtures such as carbonate stone material particle, powder, the decorating and renovating material of making by certain complete processing with lithotome decorative pattern.Yet the grinding-polishing operation at rostone can produce the useless powder of a large amount of polishings.At present, these useless powder have taken a large amount of soils mainly based on landfill, and the environment of locality has been caused than havoc, have had a strong impact on the Sustainable development of rostone industry.Therefore, the technology of utilizing of the useless powder of research rostone polishing has vast potential for future development.
" Effect of polymer cement modifiers on mechanical and physical properties of polymer-modified mortar using recycled artificial marble waste fine aggregate " that the Eui-Hwan Hwang of The report of the useless powder recycling of relevant rostone polishing is less. Korea S state-run public state university etc. delivered in " Journal of Industrial and Engineering Chemistry " the 14th phase in 2008 reported with the useless powder of artificial stone as the fine aggregate preparation polymer modified cement-concrete. In addition, " utilizing the stone material waste material to produce polyester artificial marble " that the Chu Ling of Nanjing University of Technology etc. delivered in " Guangdong building materials " the 3rd phase in 2010 reported with useless powder of stone material and unsaturated polyester and prepared the polyester artificial stone that meets quality standard, but used useless powder is through pre-treatment, its resin demand is 37% of a rostone weight, 8%～10% resin demand far above general rostone, obviously increase production cost, be unfavorable for the marketing application.
The main component of the useless powder of rostone polishing is marble and quartz, and the constituent class of main aggregate is the useless powder cyclically utilizing of rostone polishing a comparatively ideal approach in the production rostone together in filling a prescription with rostone.Yet 8% the unsaturated polyester of curing of having an appointment in the useless powder of polishing is coated on the stone flour surface, and its surface has a lot of polar groups, as-OH ,-COOH etc., cause it to be easy to reunite, and have higher oil-absorption(number).Therefore, the preconditioning technique of the useless powder of research and development rostone polishing, and it is significant to make it to be applicable to that the resin type rostone is produced in regeneration.
Summary of the invention
Purpose of the present invention solves above-mentioned the deficiencies in the prior art exactly, and the pretreatment process of the useless powder of a kind of reuse rostone polishing is provided, with improve the dispersed of useless powder and and resin compatible; Be back to the preparation rostone, improve the useless powder resource utilization degree of rostone, under the good premise of ensuring the quality of products, farthest reduce production costs.
The objective of the invention is to realize by following concrete technical scheme:
The pre-treatment reuse method of the useless powder of a kind of rostone polishing is characterized in that comprising the steps:
(1) the useless powder of rostone polishing is dried 1-3h down at 90～110 ℃;
(2) in the useless powder of polishing, stir 20-60min behind the waste stone dust treatment agent of the useless grain weight amount 0.5-3% of adding polishing, make the useless powder of pre-treatment rostone polishing; By weight percentage, the stearic acid of the trolamine of consisting of of described waste stone dust treatment agent: 60%-90%, 2%-20% and 8%-30% vinylbenzene.
(3) the useless powder after the processing is back to preparation resin type rostone: with the useless powder of the pretreated rostone polishing of step (2), 30～50 order marble powders, 60～80 order marble powders and 100～200 order marble powders are 7～15: 2～5 according to mass ratio: 50～70: 11～15 mixed mixed powders that get, the unsaturated polyester that adds mixed powder quality 8%～10%, the promotor that other adds unsaturated polyester weight 0.7%～0.9% mixes 0.5～0.7min, the solidifying agent that adds unsaturated polyester weight 0.8%～1% again mixes 0.5～0.7min, makes compound; Behind the compound injection molding, jolt-squeezing through vacuum makes the resin type rostone.
The useless powder of described rostone polishing refers to the useless powder that polishing process produces in the rostone production process.
The useless powder main component that polishing process produces in this rostone production process is lime carbonate and silicon-dioxide, also contains low amounts of resin.
The described vacuum technology of jolt-squeezing is to be evacuated down to-90KPa behind the compound injection molding; Under the vibrational frequency of 2kg～3kg pressure, 290Hz～300Hz, suppress 1-1.5min; The demoulding; Grinding behind the normal temperature placement 4h, polishing.
The used promotor of the present invention is the artificial field promotor commonly used that is equipped with made of stones, and main component is a cobalt iso-octoate.As the special-purpose promotor of the Feitian board rostone of Fanyu, Guangdong chemical industry Industrial Co., Ltd. production.
The solidifying agent rostone preparation field solidifying agent commonly used that the present invention is used, main component is a methylethyl ketone peroxide.As Fanyu, Guangdong chemical industry Industrial Co., Ltd. production Feitian board rostone special curing agent.
Unsaturated polyester can be selected adjacent benzene type unsaturated polyester resin or metaphenylene unsaturated polyester resin for use, as the 601# and the adjacent benzene type of the 603# unsaturated polyester resin of the fast Industrial Co., Ltd. of Guangdong China production, and the 828# metaphenylene unsaturated polyester resin.
Compared with prior art, the present invention has following advantage:
The present invention is back to preparation resin type rostone again by with the useless powder pre-treatment of rostone polishing.Its treatment agent wide material sources, cheap, can reduce production costs, and pretreatment technology is simple and easy; Under 10% the condition of being not more than of resin demand, prepared resin type rostone surface quality is good, not only reduces powder and reunites, and is beneficial to dispersion, and improves the viscosifying power of powder and resin, and its bending strength ratio is without pretreated goods raising more than 20%.Simultaneously, the present invention makes the useless powder of rostone polishing be able to the efficient resource utilization.
