Abstract
The invention discloses a method for preparing a silicon dioxide aerogel modified glass wool board for external thermal insulation. The method is characterized by comprising the following steps: preparing modified silicon dioxide aerogel slurry firstly, and treating a glass wool board by using the prepared modified silicon dioxide aerogel slurry, wherein the modified silicon dioxide aerogel slurry is prepared from raw materials, including silicon dioxide aerogel, a modifier, a surfactant and a solvent; the modifier is a silane coupling agent KH550, KH560 or KH570; the surfactant is Tween 80; the solvent is deionized water or an ethanol solvent. The heat conduction coefficient of the silicon dioxide aerogel modified glass wool board is low, particularly is 0.020W/(M.K), however the heat conduction coefficient of a conventional glass woof board is 0.038 W/(M.K); the resisting temperature of the modified glass woof board is increased to 650 DEG C from 400 DEG C; as the heat conduction coefficient of the glass woof board is reduced, the thickness of the glass woof board is reduced by about 50%, the construction efficiency of operators is greatly improved, and the comprehensive cost is lowered.
Description
Technical field
The present invention relates to the preparation method of Surgery therapy block of glass wool, concretely, relate to a kind of preparation method of aerosil modification Surgery therapy block of glass wool.
Technical background
Wall heat insulation material conventional at present is mainly divided into inorganic and organic two classes, organic materials quality is light, insulation, good heat-insulation effect, but its maximum defect is that fire savety is poor, easy firing, and during burning, smog is large, toxicity large, safety in utilization is not so good as inorganic heat insulation material.Inorganic heat insulation material fire resistance is good, and does not have toxicity, and its range of application is more and more extensive.
Block of glass wool, as the one of inorganic heat insulation material, is carry out fibrosis by after glass melting, processes by adding adhesive cures.Block of glass wool is widely used in external wall, plays insulation, heat insulation, sound-absorbing, Noise Reduction.Existing block of glass wool thermal conductivity as exterior-wall heat insulation is high, and be generally 0.038W/ (MK), heat insulation effect is undesirable, is difficult to meet building energy conservation 75% standard-required; High thermal resistance is lower, is 400 DEG C, applies limited; And for reaching thermal requirements, the thickness of block of glass wool must be increased, because this increasing difficulty of construction and construction cost.
Summary of the invention
The object of the invention is the thermal conductivity reducing existing external wall outer insulation block of glass wool, improve its heat insulation effect.Meanwhile, by reducing its thermal conductivity, reduce the thickness of block of glass wool, thus improve workman's operating efficiency, reduce integrated construction cost.
The preparation method realizing a kind of aerosil modification Surgery therapy block of glass wool of the present invention first prepares improved silica aerogel slurry, then uses improved silica aerogel slurry process block of glass wool.
One, improved silica aerogel slurry preparation
First select the raw material of improved silica aerogel slurry, and press column weight amount (%) preparation:
Wherein, properties-correcting agent is Silane coupling agent KH550, KH560 or KH570; Tensio-active agent is tween 80; Solvent is deionized water or ethanol kind solvent;
After improved silica aerogel slurry proportioning raw materials is selected, follow these steps to make:
(1) tensio-active agent and solvent are joined in stirred pot, stir 10-20 minute with the speed of 500-800 rev/min, make tensio-active agent in a solvent dispersed;
(2) aerosil is added in the tensio-active agent be stirred and solvent liquid, stir 30-60 minute with the speed of 500-800 rev/min, prepare finely dispersed aerosil slurry;
(3) in finely dispersed aerosil slurry, add properties-correcting agent, stir 20-30 minute with the speed of 500-800 rev/min, prepare the aerosil slurry of modification.
Two, with the aerosil slurry process block of glass wool of modification:
After the aerosil slurry of modification makes, be poured in ready container, block of glass wool is all infiltrated wherein, taking out after 20-40 minute is placed on dividing plate, after no longer including slurry and flowing out, insert in drying baker, by little of complete drying for the block of glass wool oven dry 24-48 infiltrating aerosil at the temperature of 30-80 DEG C, namely obtain aerosil modification Surgery therapy block of glass wool of the present invention.
Aerosil modification Surgery therapy block of glass wool of the present invention, compared with existing block of glass wool, has the following advantages:
(1) thermal conductivity is low, be 0.020W/ (MK), and existing block of glass wool thermal conductivity is 0.038W/ (MK);
(2) heat resistance is good, and the block of glass wool temperature tolerance through modification brings up to 650 DEG C by 400 DEG C;
(3) operating efficiency is high, by reducing its thermal conductivity, can reduce the thickness of block of glass wool about 50%, can greatly improve workman's operating efficiency, reduces comprehensive cost.
Embodiment
