Abstract

The shapes of the product are square, rectangle and tile shape, the main composition consists of main material, gelling material and compound additives. The main material is composed of 30-60 (by weight percentage) of fly ash, 30-52 of expanded pearlite. The gelling material consists of 7-24 of cement or 10-22 of water glass. The compound additives consist of 0.3-0.8 of siliceous dust, 0.1-0.3 of pure soda, 0.1-0.3 of alunite, 0.3-0.8 of NNO diffuser and 0.02-0.05 of triethanolamine. Said product is suitable for heat insulation of various equipments, pipeline, kiln and buildings.

Description

Insulation tile and its making method

The present invention relates to a kind of insulation tile and making method thereof, belong to the thermal insulation technology field, be applicable to various device, pipeline, kiln and building heat insulation.

The lagging material of current application has traditional lagging material and heat insulating material, tradition lagging material such as asbestos, vermiculite, diatomite, pearlstone, mineral wool and goods thereof, its shortcoming is that content is big, the thermal conductivity height, ultimate compression strength is lower, heat insulating material mostly is lotion such as disclosed inorganic composite insulating material of CN1076921A and manufacture technology thereof, be that employing flyash and pearlstone are aggregate, sepiolite, asbestos, wilkinite is a filler, with water, tackiness agent, the mashed prod that permeate agent combines, has moulding at random, drying shrinkage is low, advantages such as good heat insulating, still, owing to be lotion, unit weight is big, the inconvenience transportation, moulding or construction are dry slow, long construction period.

The objective of the invention is to overcome the weak point in the above-mentioned background technology, is major ingredient and provide a kind of with flyash and pearlstone, good heat insulating, and body is light, easy construction, short construction period, insulation tile of being convenient to transport and making method thereof.

The object of the present invention is achieved like this: this shape of product is square, rectangle and watt shape, major ingredient is with flyash, pearlstone is a major ingredient, with cement or water glass is gelling material, with the silicon ash, soda ash, alunite, the NNO diffusant, trolamine is a compound additive, its proportioning (weight ratio) is: flyash 30～60%, pearlstone 30～52%, cement 7～24% or water glass 10～22%, silicon ash 0.3～0.8%, soda ash 0.1～0.3%, alunite 0.1～0.3%, NNO diffusant 0.3～0.8%, trolamine 0.02～0.05%, the major ingredient pearlstone is the good light body aggregate of thermal and insulating performance, major ingredient flyash floats pearl and 70% above cenosphere because of containing, not only has function of heat insulation, under the exciting of compound additive, its lateral reactivity discharges, also play second pectisation, because the fly ash grain surface is by the hard glassiness shell parcel of one deck, after compound additive adds, destroy its outer hard glass body, break siloxane bond and alumina key in the vitreum network, the silicon-oxy tetrahedron on fly ash grain surface is disintegrated, quicken the activation of flyash, improve the reactivity of flyash, improve the microtexture of powdered coal ash product, form fibrous and cancellated hydrate, generate more hydrated calcium silicate and drated calcium aluminate, make flyash become second gelling material, improve the intensity of powdered coal ash product.

Flyash in the above-mentioned materials is the second class powered coal ash of GB1596-91 GB regulation, and pearlstone is a first grade.

The making method of this product is: at first with flyash, pearlstone, cement or water glass, the silicon ash, soda ash, alunite mixes, again with the NNO diffusant in the admixture with 80 ℃ of water dissolution, trolamine dilutes with normal-temperature water, more than two kinds of dissolvings, admixture after the dilution adds furnishing slurries in the spice water, the 40-55% of the suitable component gross weight of spice water, stir into half-dried material with the siccative that mixes again, inject mould, in the forming under the pressure of 8～12MPa, the demoulding immediately, piling, with cement is first gelling material, and water seasoning after 24 hours is first gelling material with water glass, natural curing is finished product after the drying.

Purpose of the present invention can also reach by following measure: the basic recipe of this product (weight ratio) is: flyash 50%, pearlstone 40%, cement 8.57%, silicon ash 0.5%, soda ash 0.2%, alunite 0.2%, NNO diffusant 0.5%, trolamine 0.03%, or basic recipe (weight ratio) is: flyash 45%, pearlstone 43%, water glass 10.57%, silicon ash 0.5%, soda ash 0.2%, alunite 0.2%, NNO diffusant 0.5%, trolamine 0.03%.

The present invention compares with technical background, has the following advantages and effect:

1. good thermal and insulating performance is arranged, can improve the factory building Working environment, protection operating worker health is raised labour efficiency.

2. industrial residue-the flyash with the fuel-burning power plant discharging is main raw material, supports former enriching, and cost is low, opens up a new way for total utilization of PCA simultaneously.

3. this product is nontoxic, tasteless, pollution-free, acidproof, alkaline-resisting, high temperature resistant, is good fire prevention, heat-insulation and heat-preservation material.

4. this product is convenient to transportation and is stored, and easy construction, speed are fast, compare with the lotion lagging material, can shorten construction period.
