Description

A kind of insulation putty for architectural exterior wall
Technical field
The present invention relates to building putties technical field, particularly relate to a kind of insulation putty for architectural exterior wall.
Background technology
Along with industrial expansion and the raising of living standards of the people, the demand of the energy is continuously increased by people, and the energy lacks Mouth continues to increase.Building industry is one of China's fastest-rising industry of current energy resource consumption, and at present, China's town and country existing building is total Area about 40,000,000,000 square metres, these buildings in use, its heating, air-conditioning, ventilate, energy that the aspect such as illumination consumes Having accounted for about the 30% of whole nation total energy consumption, along with the fast development of real estate in recent years, this ratio is also riseing year by year, according to Achievement by advanced countries, the ratio that building energy consumption is shared in Chinese society's terminal total energy consumption, about 35% will be stepped up, because of This, it is necessary to pay attention to Energy Conservation Project in Construction, the consumption of the energy is greatly reduced, alleviate China's energy supply and demand contradiction, reduce environment Pollute and greenhouse effect, to keep the sustainable development of national economy.
In " haydites of book structure and the preparation of heat preservation putty and correlated performance research " literary composition, author uses natural resources shale to make For wall thermal insulating heat-barrier material, article points out that slate flour physicochemical property is stable, and heat conductivity is relatively low, is suitable as being incubated merit Can filler, and the present invention uses slate flour and glass bead to be functional stuffing, cement and rubber powder composition base material, and in addition fine Dimension manufactures experimently shale insulated putty, and uses orthogonal design to obtain the optimal proportion of each component, test result indicate that, glass bead And the heat conductivity of heat preservation putty is had a significant impact by shale, the consumption of glass bead is fixing to the shrinkage factor one of heat preservation putty Ringing, finally obtaining optimal parameter is: slate flour: glass bead: cement and other auxiliary agents are according to mass ratio 50:22:15:4 Mixing, the heat preservation putty heat conductivity of preparation is up to 0.087W/(m K), although the heat preservation putty obtained in this invention has good Good effect of heat insulation, but do not reach the most far away energy-saving and cost-reducing in practice, and it is greasy to external wall to can not meet people The use demand that sub-material is the highest, and the filler such as glass microballoon is applied directly in putty material, bad dispersibility, it is impossible to have The performance having given play to self of effect, it is impossible to give the new performance of material, so the surface-functionalized of hollow glass micropearl is to carry The key of high hollow glass bead composite performance.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of insulation putty for architectural exterior wall.
The present invention is achieved by the following technical solutions:
A kind of insulation putty for architectural exterior wall, is made up of the raw material of following weight portion: cement 24-32, hollow glass micropearl 18-25, Tetraethyl orthosilicate 3.5-5, dehydrated alcohol 31-38,1mol/L hydrochloric acid 0.35-0.5, template F1271.6-2.5, emulsifying agent OP-100.7-1, sodium bicarbonate 0.4-0.6, Ludox 12-15, Ammonium persulfate. 0.3-0.5, lightweight sand 10-15, polypropylene 4-6, Perlite 1.2-1.8, phosphorus slag 4-6, carboxylic propyl methocel 2.5-3, deionized water are appropriate.
Described a kind of insulation putty for architectural exterior wall, is made up of following concrete steps:
(1) hollow glass micropearl is impregnated in the sodium hydroxide solution that mass concentration is 3-5g/L of 80 DEG C and carries out oil processing 20-30min, taking-up deionized water is rinsed post-drying well, then it is at room temperature placed in 1-2g/L Fluohydric acid. corrosion 20min, takes out and is placed in ultrasonic cleaner cleaning, then it is standby to obtain microballon through vacuum filtration;
(2) hydrochloric acid of tetraethyl orthosilicate, the dehydrated alcohol of 1/2, deionized water and 1mol/L is stirred at 65 DEG C 1-2h to mix Close uniformly, obtain silicon dioxide gel, template F127 is extremely dissolved by remaining absolute ethyl alcohol and stirring simultaneously, add self The silane coupler of weight 0.5-1%, is added to product prepared by step (1) wherein after stirring and ultrasonic disperse is uniform, Being added in above-mentioned silicon dioxide gel by this mixed liquor, be stirred at room temperature 1-2h, stirring end is placed in 60 DEG C of baking ovens Evaporate into dry, be subsequently placed in Muffle furnace and calcine 3-4h in 550-600 DEG C, naturally cool to room temperature;
(3) adding emulsifier op-10, sodium bicarbonate, deionized water and Ludox in four-hole boiling flask, water bath with thermostatic control is heated to instead Answering temperature is 80 DEG C, the Ammonium persulfate. of addition 3/5 and the butyl acrylate of 1/10 and cinnamic mixture, and at the uniform velocity stirring is to breast There is blue light, dropping residue mix monomer, it is ensured that dripping off in 3h, be subsequently adding remaining Ammonium persulfate., temperature reaction is extremely in liquid 85 DEG C, be cooled to after isothermal reaction 1-1.5h at 40 DEG C regulate pH value to 7-8, standby after natural cooling;
(4) be heated to melting by polypropylene, be added in melt polypropylene after crushed crude pearlite is broken into micropowder, with 1000-1200 turn/ Stir under Fen, then melt spinning, standby after natural cooling;Leftover materials are added to grinding machine for grinding, add step Suddenly the product that prepared by (2), step (3) and step (4), grinds uniformly and get final product.
The invention have the advantage that the present invention uses hollow glass micropearl as main filler, it has excellent resistance to compression Intensity is high, fusing point high, resistivity is high, thermal conductivity coefficient and the feature such as Thermal Contraction Coefficient is little, and the most obvious loss of weight and sound insulation Heat insulation effect, but the surface-functionalized key being to improve its composite property of hollow glass micropearl, so with Fluohydric acid. pair Its surface corrosion, improves surface area, and recycling chemical method generates order mesoporous silicon dioxide gel and is coated on its surface, enters One step improves its lightweight, fire prevention, the performance such as heat insulation, improves adhesion in the base simultaneously, the powder of lacquer putty for use on water suction of cement based It is easily generated cracking, and most binding agent all has hydrophilic, use emulsion polymerization for solving this problem present invention Having synthesized Ludox/phenylpropyl alcohol compounded latex, its caking property is high, good waterproof performance, and resistance to water is high, it is possible to effectively avoid putty to open Splitting, cement based putty becomes the root in crackle, crack due to the generation of internal stress cure shrinkage when, for preventing crackle Producing, the present invention adds the polypropylene fibre that anti-crack fiber is modified wherein, it is possible to stop the generation of crackle to a certain extent, Putty adhesion strength height prepared by the present invention, water-tolerant, flexible break resistant effect substantially, easy construction etc., and can be well Mate with exterior wall heat-preserving system, extend the life-span of decoration protective layer, also greatly increases heat insulation effect.
