Abstract
Disclosed is a preparing technique for fly ash fiber plate, which is characterized by preparing water-resistant agent solution in advance, the steps comprise heating water to a certain temperature, adding ethylene glycol monobutyl ether in the heating water, adding organic acid in the heating water, stirring until the organic acid is dissolved completely, thereby obtaining the water-resistant agent, further heating fly ash fiber to 100-150 DGE C, uniformly spraying acrylic resin emulsion on the fly ash fiber, keeping in the temperature and hot pressing in certain pressure intensity, thereby forming the fly ash fiber plate, further putting the fly ash fiber plate in a baking oven to a temperature from 100 DGE C to 150 DGE C, keeping the temperature, uniformly spraying the water-resistant agent solution on the fly ash fiber plate and then drying, thereby the final fly ash fiber plate is obtained. The fly ash fiber plate prepared according to the preparing technique is lightweight, water-resistant and is good in flame-proof property, which is capable of using as building materials and adapting for heat preservation of suspended ceiling and external and internal wall.
Description
Technical field
The present invention relates to a kind of technology of preparing of coal ash fiberboard material, specifically, is to prepare coal ash fiberboard material with emulsion as caking agent, the coal ash fiberboard material surface is carried out the processing method of anti-water treatment again.
Background technology
Coal ash fiber is a specific admixture inorganic oxide fibres of development in recent years.Flyash is the industrial residue and the discharge of China's maximum, is mainly derived from the residue of combustion of burning blast furnace and thermal power generation, goes beyond 600,000,000 tons every year.The main body Chemical Composition of flyash is SiO
2, Al
2O
3, CaO, Fe
2O
3And a spot of TiO
2, MgO.Its most elements is identical with the contained element of original mineral products material.Along with the long-term exploitation and the use of industry, the mineral products natural resource are day by day exhausted, and coal burning waste flyash day by day increases, and is piled into sorrow.Therefore, utilize the Chemical Composition and the structural performance of flyash, its deep processing is changed into the industrial application raw material, the instead of part natural mineral resource is one of problem of investigator's interest in recent years.Fly-ash Preparation is become to have the ultra-fine inorganic fibre of high value, and then utilize fiber to realize multiple use: make paper pulp and be used to produce the cardboard paper product; Make heat preservation and soundproof lagging material and energy-saving wall material; Make light flame-retardant building room furred ceiling; Make fiber-resin composite; Be used for industrial filter material; Be used to pessimum of improving road asphalt cold cracking, hot mastication etc.
Flyash can with its fusion, adopt centrifuging, multiple roll centrifuging or blowing process to produce cellucotton by high temperature under the collocation of inorganic fusing assistant (magnesite, rhombspar, Wingdale etc.) and cullet, and its diameter is between 4 μ m-9 μ m.
The present domestic flyash fibrillating technique that realized, in the production solid residue behind flyash or the blast-furnace roasting is added necessary auxiliary agent and water, fusing at high temperature after stirring and granulation, again through pressurization, by the centrifugal silk that throws away into of multistage running roller, by cooling and surface treatment, make inorganic coal ash fiber.This fiber has been applied to the industrial heat preservation material and has made inorganic fiber paper pulp partly substituting the xylon pulp applications in paper industry.Further rationally utilize this inorganic fibre from the waste preparation, turning waste into wealth has important strategic meaning and economic worth.
