Description

The fire-resistant holllow building block of Attapulgite shale

Technical field

The present invention relates to building material field, be specifically related to the fire-resistant holllow building block of a kind of Attapulgite shale.

Background technology

Novel wall material mainly refers to take the material of construction that the non-clay resources such as sandstone, shale, industrial solid waste residue, the remaining soil of building are the starting material mechanization production; there is protection soil, protection of the environment, save energy, utilize refuse, gain in strength and the characteristic such as economic and practical; various concrete segments are widely used in construction work; but; because the reasons such as quality product, Architectural Construction, construction technology cause concrete segment cracking phenomena ubiquity; for a long time, concrete masonry cracking, hollowing, seepage are considered to the common fault of walling work.

Shale is by clay, in earth movement, to be pushed and the rock that forms, have laminated or laminar bedding, with hard thing, impact easy splinter, shale does not have viscosity, plasticity-and water-permeable are all very poor, need to will after block shale pulverizing very carefully, just can be processed into shale building block.

Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, make Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area caused to serious threat.

Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.

The volcanoclastic rock that also has with the symbiosis of attapulgite clay ore deposit, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the thickness of the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area is up to tens of rice, attapulgite clay is in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, investigate factually, the volcanoclastic rock that 1 ton of attapulgite clay of every exploitation produces has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock produced is up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, cause the serious wasting of resources and financial loss.

China Patent Publication No.: CN102765961A, open day: on November 07th, 2012, patent name is " a kind of method of utilizing shale to prepare the aerating hollow brick ", disclose " a kind of method of utilizing shale to prepare the aerating hollow brick; carry out in accordance with the following steps: (1) presses following butt mass parts mixing raw material: granularity 1000-1500 purpose shale after pulverization process; lime, flyash; (2) 85-95% by above-mentioned steps (1) mixing raw material butt quality adds water, the 0.04-0.06% of mixing raw material butt quality adds the aluminium scrap powder, the 9-11% of lime quality adds gypsum, the 1-4% peregal of aluminium scrap opaque amount, the 0.1-0.3% trolamine of lime quality etc.; Amount of shale of the present invention is large, energy-conserving and environment-protective, alleviates shale and stores up the place problem that processing brings, and provides new raw material sources for hollow brick simultaneously ".

Above-mentioned patent weak point is " by following butt mass parts mixing raw material: granularity 1000-1500 purpose shale after pulverization process; lime; flyash ", 1000-1500 purpose particle fineness is equivalent to 0.012～0.009 millimeter, the production cost that is worked into this particle fineness is very high, can not be applicable to the actual production of building materials industry.

Summary of the invention

The objective of the invention is to overcome weak point in prior art, provide a kind of Attapulgite shale fire-resistant holllow building block.

The batching of the fire-resistant holllow building block of Attapulgite shale is comprised of attapulgite clay mine tailing, shale, alumine, volcanoclastic rock mixture, wilkinite mine tailing, aluminate cement, mesh polypropylene-fibre and high performance water reducing agent of polyocarboxy acid.

The production method of the fire-resistant holllow building block of Attapulgite shale: be transported in fully-automatic building block forming machine after the batching of the fire-resistant holllow building block of Attapulgite shale is stirred, be pressed into the work in-process of holllow building block, conventional maintenance is packaged as the finished product of the fire-resistant holllow building block of Attapulgite shale after 28 days.

Attapulgite clay be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, attapulgite clay soil property exquisiteness, water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, can effectively avoid the fire-resistant holllow building block cracking of Attapulgite shale, improve intensity and the porosity of the fire-resistant holllow building block of Attapulgite shale.

Attapulgite clay can mix in recovery process a certain amount of rubble and earth, can't be sieved, and as a kind of mine tailing, abandons, and causes a large amount of wastings of resources, and the present invention selects the attapulgite clay mine tailing after pulverizing, particle fineness≤0.15 millimeter.

Shale is a kind of sedimentogeneous rock, and complicated component, but the joint that all has thin laminated or thin slice stratiform are mainly the rocks formed through pressure and temperature by the clay deposition, but wherein mix chip and other chemical substances that quartz, feldspar are arranged.According to the composition of its tramp material, can be divided into: calcareous shale, irony shale, siliceous shale, carbonaceous shale, black shale, oil shale etc.; The present invention selects the shale after pulverizing, particle fineness≤5.0 millimeter.
