Abstract
The present invention provides a plant fibre type anti-crack additive material for the field of building materials, which is characterized in that a preservative, a mildew inhibitor, a dispersing agent and a stabilizing agent are mixed in moist gramineous plant fibres, moist herb plant fibres or waste plant fibres; compared with the existing steel fibres, glass fibres, asbestos or synthetic fibres, the plant fibre type anti-crack additive material not only has the advantages of no pollution, no corrosion, small heat transfer coefficient and good heat-insulating property in the process of preparation and use, but also improves anti-crack performance, and strengthens the performance of structures of concrete, etc. The plant fibre type anti-crack additive material can be added in building materials, comprising a surface embroidery material, a thermal-insulating heat-insulating material, a fireproof material, a road surface mixed material, the concrete, a building block material without burning, plastic, an inorganic composite material, etc., and can also be used for manufacturing a sheet material; thus, the plant fibre type anti-crack additive material has wide application prospects, obvious advantages and social and economic benefit.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of anti-crack additives that is used for material of construction such as concrete.
Background technology
Material of construction such as concrete are after being applied to engineering, because load and environmental influence easily cracks, the crack, accelerate the failure and wear out.
People adopt steel fiber, or glass fibre, asbestos, and synthon such as polypropylene fibre in case the crack arrest line produces, strengthen weather resistance as adding material.But fibers such as steel fiber are in making and using, and the energy consumption height pollutes greatly, and price is expensive, and the steel fiber easy-to-rust influences the isostructural weather resistance of concrete.
Summary of the invention
The contriver is through repeatedly investigating and testing, and purpose is to attempt to develop a kind of interpolation material that adopts vegetable fibre as main raw material, is used for the isostructural cracking resistance line of concrete, has fibers such as adopting steel fiber now as adding the existing defective of material to overcome.
The technical scheme of taking of the present invention is, develops a kind of vegetable fibre type anti-crack additives, comprises following weight part raw material: vegetable fibre 1-75, and sanitas 0-5, mould inhibitor 0-5, dispersion agent 0-10, stablizer 0-10, water is an amount of.
Vegetable fibre can be a straw, wheat straw, and reed, bagasse, the straw of draft such as chaff, gramineae plant and by-product are separated fiber and wax through traditional method, also can be waste and old vegetable fibres; Sanitas can be vulkacit H or phenylformic acid, phenyl aldehyde, Whitfield's ointment, dodecyl trimethyl ammonium-2,4, all sanitass such as 5-Trichlorophenol; Mould inhibitor can be a zinc sulfate, or zinc oxide, chromic oxide, borax, Tegosept E, all mould inhibitors such as pentachlorophenol; Dispersion agent can be stearic acid or polystyrolsulfon acid, anionic water-soluble tensio-active agents such as Sodium dodecylbenzene sulfonate, cetyltrimethyl ammonium salt, cation water-soluble tensio-active agents such as dodecyl trimethyl ammonium salt, Soxylat A 25-7, non-ionic water-soluble tensio-active agents such as polyoxyethylene glycol; Stablizer can be a Natvosol, carboxymethyl cellulose, xanthan gum, polyvinyl alcohol, glycerine, organic water-soluble stablizers such as trolamine; Water is used for that vegetable fibre is moistening not to lump, and makes raw material when direct vegetable fibre with plant straw and by-product preparation, can not add water.
Above-mentioned raw materials is passed through following technical process preparation cost invention product: vegetable fibre and----add suitable quantity of water to wet even-----sneak into described sanitas, mould inhibitor, dispersion agent, stablizer-----pack.
The present invention is a main raw material with standing grain basis, herbaceous plant separated fiber or waste and old vegetable fibre, does not need to consume forest tree resource, than steel fiber, glass fibre, asbestos, fibers such as polypropylene fibre are pollution-free in preparation and use, not corrosion, heat transfer coefficient is little, good heat insulating, and geometric distribution is intersected closely, in being limited in microfracture more among a small circle, suppress to the tip expansion, cracking resistance seam performance improves, do not influence material compaction such as concrete, strengthened concrete isostructuralism energy again.Product of the present invention can be used for being added into the surface and whitewashes material, the heat-insulation and heat-preservation material, fire-retardant material, road surface mixing material, concrete, the baking-free building block material, plastics in the material of construction such as inorganic composite materials, also can be used for making packaging plate, have a extensive future, have significant advantage and economic results in society.
