Abstract
The invention discloses a process method for manufacturing an anti-crack building foam sandwich panel. The method comprises the following steps: (1) feeding 28-30 parts of pulverized wood, 5-8 parts of modified gelatine powder cellulose and 2-4 parts of foaming agent into a pre-expander for prefoaming, wherein the steam pressure of the pre-expander is 0.35-0.6MPa, and the mixture is preheated to 125-150 DEG C; ageing for 4-6h to obtain a prefoamed foaming material. According to the process method disclosed by the invention, by taking the pulverized wood as the raw material, the defects that the toughness of a phenolic resin foam-thermal insulation material is poor, the brittleness of the phenolic resin foam-thermal insulation material is high, and powder and bits are easy to fall from the phenolic resin foam-thermal insulation material are overcome; the anti-crack building foam sandwich panel also has the low heat conductivity coefficient of the phenolic resin thermal insulation material and the fire retardance of a perlite thermal insulation material, so that the anti-crack building foam sandwich panel is a wall thermal insulation material which is worthy of being popularized.
Description
Technical field
The present invention relates to building material field, specifically belong to a kind of anti-crack building foam battenboard process processed.
Background technology
When external wall uses thermal insulation material, the heat insulating materials such as many use benzene plates, extruded sheet or polyurethane foam, although these material heat insulating effect are relatively good, their fireproof performance is poor, there is potential safety hazard; Meanwhile, when using high-rise building, anti-wind pressure is lower; Polyurethane is in use with polyurethane foams foaming, and polyurethane foams can produce toxic gas in foaming process, and can not get rid of completely after doing heat-barrier material, so environmental protection coefficient reduces greatly, and cost is also very high; Glue powder polyphenyl particle, perlite particle are widely used just gradually, this heat insulating material site operation, because material is solid particle, be convenient to transport, in use using method is simple, has fireproof performance excellent, the advantageous feature such as cost is lower, and it is pollution-free, but also have problems, that is, its material poor thermal insulation property, insulation layer skin needs to smear cracking-resistant material, and insulation layer
Can carry out anticracking process after needing solidification drying after smearing, this just needs longer drying time, therefore long construction period.
Summary of the invention
The object of the present invention is to provide a kind of anti-crack building foam battenboard process processed, overcome phenolic resin foam heat insulating material poor toughness, fragility large, easily dry linting, fall the shortcoming of slag, having again the low thermal conductivity of phenolic resins heat insulating material and the fire protection flame retarding characteristic of heat insulating pearlite material, is a kind of wall thermal insulating heat-barrier material be worthy to be popularized.
Technical scheme of the present invention is as follows:
A kind of anti-crack building foam battenboard process processed, the method includes following steps:
1), by broken for 28-30 part wood powder, 5-8 part modified glue powder cellulose, 2-4 part blowing agent feed vapour pressure 0.35-06MPa, be preheating in the prefoaming machine of 125-150 DEG C and carry out prefoam, obtain the expanded material of prefoam through 4-6h slaking;
2), after the expanded material of step (1) and 8-10 part lithium chloride colloidal sol, 14-16 part alumina silicate fibre, 7-10 part quartz sand, 10-12 part asbestos, 4-6 part air entraining agent fully being stirred, mixing speed controls at 1000-1200r/min,
3), by step 2) the advanced horizontal high voltage of the compound of gained is shaping, and then solidify, last heat treatment; Obtain gypsum plank, the pressure of high-pressure molding is 5 ~ 7Mpa; The temperature of described solidification is 90 ~ 110 DEG C, and the time of solidification is 1.5 ~ 3h; Described heat treated temperature is 400 ~ 600 DEG C, and the heat treated time is 2 ~ 3h;
4), green compact sheet material external surface sprays one deck water-repellent paint, and the thickness of water-repellent paint is 0.2-0.4mm, obtains finished product sheet material.
After the expanded material of described step (2) and 9 parts of lithium chloride colloidal sols, 15 parts of alumina silicate fibres, 8 parts of quartz sands, 11 parts of asbestos, 5 parts of air entraining agents fully stir, mixing speed controls at 1100r/min.
The present invention compared with prior art tool has the following advantages:
The present invention adopts broken wood powder to be raw material, overcome phenolic resin foam heat insulating material poor toughness, fragility large, easily dry linting, fall the shortcoming of slag, having again the low thermal conductivity of phenolic resins heat insulating material and the fire protection flame retarding characteristic of heat insulating pearlite material, is a kind of wall thermal insulating heat-barrier material be worthy to be popularized.
