Description

A kind of alkaline residue-gangue novel decorative plate
Technical field
The present invention relates to a kind of novel decorative plate of alkaline residue-gangue, in particular to a kind of exterior wall of alkaline residue-gangue Decorative panel and preparation method thereof.
Background technique
Environment is the basic premise of human survival and development.Environment for our survival and development provide required resource and Condition.Therefore, the reform of traditional decoration plate technique and make full use of waste residue again and become raw material can obtain economic, environment sum Various benefits of society.
In particular, there are commonly building coating, exterior wall tile, glass curtains for the building exposed wall decoration material researched and developed in recent years Wall, ceramic hanging board, aluminium sheet, aluminium-plastic panel etc..Exterior coating is safe, rich in color, easy to be updated, but to such as cracking resistance of wall Property, weather-proof durability protective value it is poor, and easily dirty, fugitive color；And reflective, ceramic hanging board the high density of glass curtain wall and outer Wall brick dead weight is big, brings potential danger in exterior wall skyscraper use, and usually high temperature is fired, and belongs to high pollution high energy It consumes class product, security risk and environmentally friendly hidden danger and deposits.Aluminium sheet, the metals class external wall decorative material such as aluminium-plastic panel is due to its cost height High, installation requirement is complicated, it is difficult to universal.Therefore, people put forth effort to research and develop it is cheap, environmentally friendly, be readily produced, and it is light weight, strong The outer wall decoration board that degree is high, toughness is high, durability is good, shrinking percentage is low.
Gangue contains a large amount of clay class mineral, has certain pozzolanic activity after certain temperature is calcined, mixes Alkali-activated carbonatite gangue cementitious material is formed after adding certain alkali-activator, gangue can be made to turn waste into wealth, realize high added value It recycles.Alkaline residue refers to the alkaline scrap material that alkaline and alkali process are discharged in the process in industrial production, and composition mainly includes carbonic acid The calcium salts such as calcium, calcium sulfate, calcium chloride are the waste residue of main component, also containing compositions such as a small amount of sulfur dioxide, since it contains A large amount of chloride becomes reluctant solid waste, and the serious pollution environment of alkaline residue stockpiling restricts the development of basic industry.
Alkali-activated carbonatite cementitious material is a kind of cementitious material generated by potential cement components and alkali-activator reaction, With abundant raw materials (using trade waste), preparation is simple and low power consumption and other advantages, and has both good corrosion resistant, resistance to The performances such as high temperature.Wherein, potential gel rubber material component is mainly metakaolin, granulated blast-furnace slag, granulation phosphorus slag and flyash Deng.Alkali-activator is mainly caustic alkali, soluble silicate or non-silicate.Alkali-activated carbonatite cementitious material and Conventional Portland water Mud is compared, and has many advantages, such as that requirement is small, the heat of hydration is low, intensity is high and durability is good.And the ingredient of the type of alkali-activator, slag The Nomenclature Composition and Structure of Complexes of hydrated product can be all set to generate larger difference with the difference of structure.(application study of alkali-activated carbonatite cementitious material, Zhang Bo (173) 53, the 3rd phase of volume 23 " Chinese gelling agent " in March, the 2014th)
Experiment discovery of the present inventor by long-term and arduous exploration and repeatedly produces exterior wall using alkali-activated carbonatite cementitious material Decorative panel needs solve the problems, such as following many numerous and jumbled: how potential gel rubber material component are selected out from countless possible schemes Compounding to improve early hydration speed and generate high-intensitive product, reach anticorrosive decorative plate of outer wall, shock resistance, resist it is tired The performance indexess such as labor, toughness are high, durability is good, shrinking percentage is low etc.；How appropriate alkali-activator is prepared in aquation mistake To the potential gel rubber material activity excitation of compounding in journey, its latent hydraulicity is made to be not fully exerted；How thin pulp thin material is improved At base quality and how to realize that pipelining reaches batch production.A series of this linksystem problem becomes alkali-activated carbonatite gelling material Expect the difficult point of industrialization production decorative plate of outer wall.
Summary of the invention
In view of this, in order to overcome above-mentioned difficult point, the present invention provides a kind of novel decorative plate preparation side of alkaline residue-gangue Method, the technical solution have given full play to alkaline residue-gangue latent hydraulicity, and high-intensitive produce is generated in higher hydration rate Object to reach decorative plate of outer wall performance indexes, and ensure that plate at base quality, it can be achieved that batch production assembly line Operation.
