Description

A kind of environment-friendly type foaming at normal temp glass material goods and manufacturing process thereof

Technical field

The present invention relates to a kind of environment-friendly type foaming at normal temp glass material goods and manufacturing process thereof, facade, ground and the roof etc. that specifically are used for the building by laying bricks or stones of building masonry wall, external and internal wall, buildings is played attenuating weight, sound insulation and insulation, dampproof effect, belong to the plastics products for building technical field.

Background technology

At present, being used for the insulation of buildings external and internal wall is to adopt various organic insulation materials that buildings is incubated basically, and ground is not done insulation and soundproof measures substantially.And organic materials have do not prevent fires, not sound insulation, easy aging, quality soft characteristic, wearing quality, security and life-span to buildings have proposed challenge, and it is unfavorable and cause the neighborhood anxiety owing to not sound insulation to the energy-saving and emission-reduction of buildings that insulation and soundproof measures are not done in the ground in various residential buildings and commercial building.And existing inorganic heat insulation material, as foam cement, foaming plaster goods etc. are owing to intensity very low (general folding strength is less than 1Mpa) is greatly limited in practice, so can't extensively promote.

Application number is that 200710178169.6 light heat-insulating materials and preparation method thereof disclose a kind of light heat-insulating material and preparation method thereof, comprise the silico-aluminate polymkeric substance, the mol ratio of silicon and aluminium is in the silico-aluminate polymkeric substance: 1≤Si/Al≤3 comprise that mass ratio is the solid material of silicon-aluminum containing such as 50～85% flyash, kaolin, coal gangue, slag; 14.5～48% liquid basified exciting agent; 0.5～2% whipping agent.Liquid basified exciting agent comprises caustic solution and water glass, mix stirring with solid material and whipping agent, make a kind of direct cast that both had been applicable to, be applicable to that again mould molding is prefabricated, thermal insulation, the cold insulation of making cold and hot equipment both be applicable to, also be applicable to and make large-scale thermal insulation, sound insulation, fp house wallboard, roof heat-insulating shield.The main drawback of this invention is a complex process, needs a large amount of waters and forms water and pollute, and needs to use caustic solutions and water glass and proportioning is had requirement in a large number, and goods are needed specific maintenance etc.

For wearing quality, security and life-span of improving buildings and the deadweight that alleviates buildings, make and get along amiably and peacefully between the neighbours not because of noise causes strained relations, building energy-efficient, reduction of discharging, environmental protection and harmonious living environment is the active demand of Chinese society, sustainable economic development.

Summary of the invention

Main purpose of the present invention is to overcome above-mentioned weak point, providing a kind of is 65-95% to utilize cullet, other depleted inorganic non-metallic compound-material is 5-35%, add a kind of composite foam material 3-10%, through ball mill pulverizing and stirring 2-6 hour that be mixed, fineness reaches 240 orders, cooperate quantitative inorganic fibers 0-5% or structural steel 0-8%, adding the silicate colloid evenly is in harmonious proportion, whitewash on floor or body of wall or cast directly on the buildings or be placed into shape, make product in the mould of size, whipping agent and silicate cement precursor reactant produce a large amount of gases, these gases are wrapped in the full-bodied silicate colloid, volume of mixture expands, and forms the foam material of vesicular structure, becomes high-intensity foamed glass material after the seasoning.

Depleted ceramic of the present invention is various cullet, flyash, metal and nonmetal slag, waste ceramic, sand, quartz, feldspar, wollastonite etc.;

Whipping agent of the present invention is lime carbonate, magnesium hydroxide, magnesium oxide, ammonium nitrate etc.;

Silicate colloid of the present invention is the mixture of potassium silicate, water glass;

Inorganic fibers of the present invention is glass fibre, mullite fiber, slag fibre etc.;

Structural steel of the present invention is metal wires such as ￠ 4, ￠ 6, ￠ 8, ￠ 10.

Compared with the prior art the present invention has the following advantages:

It is main raw material that the present invention adopts the depleted ceramic, account for the 90-97% of the total consumption of raw material, wherein cullet is 65-95%, add a small amount of specific whipping agent and inorganic fibers, adding the silicate colloid can be as place or the certain location of the use of using sand-cement slurry at needs after evenly being in harmonious proportion, and waits formation behind nature typing and the complete drying to have the foamed glass product of independent sealed porosity.Technology of the present invention is simple, with low cost, do not need sintering, do not need to carry out cutting processing, energy-conserving and environment-protective, use inorganic fibers or steel as strongthener, need not modulate caustic solution separately, not need to grind respectively separately, not need independent maintenance raw-material fineness requirement is low, can can prefabricated shaping prod as using sand-cement slurry both can directly use also, overcome the shortcoming of the strained relations that cause because of noise between the neighbours simultaneously again.Product performance reach density 0.2-1g/ cubic centimetre; Folding strength 3-12Mp is the breakthrough of building material field.
