Description

A kind of diatomite-flyash type underfill composition and application thereof
Technical field
The present invention relates to building material field, especially relate to spackling and application thereof.
Background technology
Diatomite is a kind of biogenic silicastone, be the remains of the diatoms grown in ocean or lake at subaqueous deposit, a kind of non-metallic minerals formed gradually through physical environment effect.Diatomite is mainly distributed in the states such as China, the U.S., Denmark, France, Romania.Be a kind of biogenic silicastone, it formed primarily of the remains of diatom in ancient times.China's diatomite reserves 3.2 hundred million tons, prospective reserves reaches more than 20 hundred million tons, mainly concentrates on East China and the Northeast, wherein larger, and what reserves were more has the provinces such as Jilin (54.8%), Zhejiang, Yunnan, Shandong, Sichuan.
Diatomite tool has the following advantages.(1) pH value is neutral, nontoxic, and suspension property is good, and absorption property is strong, and unit weight is light, and mixing uniformity is good; (2) diatomite makes additive in cement, can improve intensity, makes SiO2 in cement become active; (3) diatomite has excellent extensibility, has the aspect high-quality effects such as the soft wear resistance of higher shock strength, tensile strength, tear strength, light weight is good, ultimate compression strength is good.
Flyash is the powder collected from coal-powder boiler flue gas.Shi Ge big coal country of China take coal as the basic fuel of electrical production.The energy industry stable development of China, power generation capacity annual growth is 7.3%, developing rapidly of power industry, bring the sharply increase of flyash quantity discharged, annual the discharged flyash total amount of Hazards in Power Plant increases year by year, nineteen ninety-five flyash quantity discharged reach 1.25 hundred million tons, within 2000, be about 1.5 hundred million tons, 300,000,000 tons will be reached by 2010, cause huge pressure to the development of the national economy of China and ecotope.On the other hand, China is again the limited country of a per capita resource reserve, the comprehensive utilization of flyash, turn waste into wealth, turn bane into boon, to become in China's economic construction an important techno-economic policy, solve China electrical production environmental pollution, the important means of contradiction between resource shortage, be also electrical production one of the task of facing solution.
Spackling is all products being applicable to fill seam between ceramic tile.Spackling can be divided into cement based spackling, reactive resin spackling and liquid form mixt or emulsion admixture.Wherein cement based spackling generally could mix with water or liquid form mixt before use.Spackling mainly contains cement based spackling and reactive resin type spackling on the market at present.Cement based spackling has two large inferior positions: (1) water proof anti-seepage ability, and water easily penetrates into, and causes mouldy, makes ceramic tile easily shrink hollowing; (2) surface abrasion resistance is not good enough, and easy contaminated thing is stained, and cleans difficulty, causes decorative effect poor, affect ceramic tile attractive in appearance.Though reactive resin spackling can overcome above inferior position, material, packing cost are too high, produce, mixing procedure is loaded down with trivial details, in addition containing toxic and harmfuls such as volatile organic compoundss, make it apply and are restricted.
Although diatomite has above-mentioned plurality of advantages, due to its porosity and extensibility high and make it be generally considered improper for spackling.
Summary of the invention
In cement based spackling, using existing problem in order to solving diatomite, the invention provides a kind of diatomite-flyash type underfill composition and application thereof.
First aspect present invention provides a kind of diatomite-flyash type underfill composition, wherein, and described composition composed as follows:
The diatomite of (1) 20 weight part to 40 weight part;
The flyash of (2) 10 weight part to 15 weight parts, or the quartz sand of 20 weight part to 40 weight parts;
The wilkinite of (3) 0.5 weight part to 2.5 weight parts;
The water-ground limestone of (4) 4 weight part to 6 weight parts;
The water glass of (5) 1 weight part to 2 weight parts;
The calcite in powder of (6) 10 weight part to 20 weight parts;
The sepiolite powder of (7) 4 weight part to 8 weight parts;
The titanium dioxide of (8) 2 weight part to 4 weight parts;
The Mierocrystalline cellulose of (9) 1 weight part to 2 weight parts, described Mierocrystalline cellulose selects at least one in free hydroxy ethyl cellulose, hydroxyethylmethyl-cellulose, Vltra tears; With
The cement of (10) 30 weight part to 40 weight parts.
The present invention provides composition described in first aspect present invention as the application in partition wall spackling in second aspect.
The invention enables and diatomite can be used as spackling, the various advantages making spackling can have diatomite thus to bring, such as (1) pH value is neutral, nontoxic, and unit weight is light, and mixing uniformity is good; (2) diatomite makes additive in cement, can improve intensity, makes SiO2 in cement become active; (3) diatomite has the aspect high-quality effects such as the soft wear resistance of higher shock strength, tensile strength, tear strength, light weight is good, ultimate compression strength is good, can reduce and cause flexible because of humidity change.Therefore, diatomite of the present invention-flyash type underfill composition is a kind of spackling with excellent properties, is particularly suitable for the joint filling operation of indoor partition wall ceramic surface tile.
Embodiment
The present invention provides a kind of diatomite-flyash type underfill composition in first aspect, wherein, and described composition composed as follows:
