Wood fibre (xylemfiber) is that natural reproducible timber processes through chemical treatment, mechanical process the organic wadding fibrous material obtained.Being widely used in the fields such as concrete mortar, plastering, wood pulp sponge, asphalt roads, having good effect to preventing coating cracking, raising water-retentivity, the stability improving production and the conformance of construction, the sticking power etc. of effects on surface of gaining in strength, strengthen.Its technical role is mainly: thixotroping, protection, absorption, carrier and weighting agent.。
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of inorganic heat insulation mortar containing wood fibre not easy to crack.
The present invention is achieved by the following technical solutions:
A kind of inorganic heat insulation mortar containing wood fibre not easy to crack; it is obtained by the raw material of following weight parts: Rutile type Titanium Dioxide 1-3; glass bead 15-17; wood fibre 4-6; vinyl-acetic ester 1-2, acrylate 1-3, sodium-chlor 1-2, gum arabic 1-2, waste polystyrene foam plastic particle 1-2, glass fibre 1-3; chromium acetate 0.1-0.2, ether of cellulose 0.2-0.4, cement 30-40, wilkinite 15-18, flyash 11-18, coating slag 10-18, water is appropriate;
Coating slag is obtained by the raw material of following weight parts:
Blast-furnace slag 20-30, Sodium hexametaphosphate 99 1-2, methacrylic acid 0.3-0.5, vinylformic acid 0.1-0.4, acrylamide 1-2, nano-calcium carbonate 1-3, benzene emulsion 5-9, Ben-zylphenol Polyoxyethyl Ether 1.5-3.8, glycerin fatty acid ester 1.3-1.6, water is appropriate;
The preparation method of coating slag is:
(1) blast-furnace slag is soak 10-12 hour in the hydrochloric acid of 5-7% in concentration, filters, and dries, and grinding is crossed 100-200 mesh sieve, obtained Treated By Modified Slag powder for subsequent use;
(2), after Sodium hexametaphosphate 99, methacrylic acid, vinylformic acid, acrylamide mixing, add suitable quantity of water, stir, then add benzene emulsion, Ben-zylphenol Polyoxyethyl Ether, be warming up to 50-60 DEG C, stir under 200-100rpm, obtain compositional liquor for subsequent use;
(3) suitable quantity of water diluting modification slag powders is the slurry of concentration 20-50wt%, add glycerin fatty acid ester in the slurry, pH is adjusted to be 8-10 with inorganic alkali solution, 70-90 DEG C is warmed up to after high speed dispersion 30-60min, adjust pH is 6-7, then adds compositional liquor and all the other raw materials, stirs, dry, to obtain final product.
The described inorganic heat insulation mortar containing wood fibre a kind of not easy to crack,
Preparation method comprises the following steps:
