Description
Technical field
The present invention relates to material of construction preparation field, be specifically related to a kind of heat-insulation and heat-preservation composite building material.
Background technology
Current, due to the climate change that greenhouse gases bring, there is very hot or extremely cold weather in a lot of area, refrigeration or the air-conditioning system that heats to be opened to meet the comfortable life temperature of people in the building place domestic demand of people's activity, but the non-lagging material generally using thermal conductivity larger due to current construction wall builds up, easily cause higher energy consumption, very uneconomical.Along with the develop rapidly of China's economy, coal, electricity and fossil resources are increasingly in short supply, and save energy and protection of the environment be one of fundamental state policy becoming China.In the middle of various energy consumption, building energy consumption accounting is maximum, increases the fastest, has accounted for 1/4th of national total energy consumption.
Not only can remarkable save energy at architectural use heat preserving and insulating material, and can effectively improve housing conditions.Current China adopts the building of heat preserving and insulating material to be also in developmental stage, and emphasis is the insulation of north cold area and the heat insulation of southern area.But the heat-insulation and heat-preservation material of construction used at present is all not ideal enough in various performance, especially can not meet the needs of people in insulation, weathering resistance, resistance to acids and bases etc.Lagging material ubiquity thermal conductivity of the prior art is large, than great, easily come off, the hidden danger such as moistureproofness is poor, and the interpolation composition of Conventional insulation and irritating smell easily have a negative impact to HUMAN HEALTH and environment.
Summary of the invention
The present invention is directed to the heat-insulation and heat-preservation composite building material that prior art deficiency provides the little and health environment-friendly of a kind of thermal conductivity.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of heat-insulation and heat-preservation composite building material, and it comprises the pearlstone of 20 ~ 35 weight parts, the silicate cement of 25 ~ 40 weight parts, 4 ~ 8 parts by weight of inorganic fillers, 3 ~ 6 weight part polystyrene foamed plasticss (EPS), 3 ~ 10 weight part plant fiber powders and 1 ~ 5 weight part swelling agent sodium carbonate.
Described pearlstone is the powder of order number 20 ~ 80, and thermal conductivity <0.06W/mK, tap density is even.
Described mineral filler is one or more in wilkinite, polynite, calcium carbonate and flyash, and described mineral filler is mineral filler micro mist, its granularity <0.3mm.
Described polystyrene foamed plastics (EPS) is waste polystyrene foam pulverized particles, mean particle size <1mm after crushed, and largest particle particle diameter is no more than 2.5mm; EPS possesses excellent heat-insulating property, and thermal conductivity is low, and the invention belongs to second stage employ.
Described plant fiber powder is cotton stalk fiber, described cotton stalk fiber treatment process: agriculture waste cotton stalk is through chopping off as length 5 ~ 10cm breaks bar, the bar that broken by gained to be placed in blaster and to pass into the saturated vapor of 3MPa, explosion is carried out after keeping 6 ~ 10min, obtain explosion cotton stalk fiber, and explosion cotton stalk fiber is dried to moisture content <8%; Cotton stalk can by cotton stalk fiber cell from cell interbed separately through explosion treatment, make surface attachment one deck xylogen of cotton stalk fiber, thus reduce the polarity of fiber surface, improve the consistency between fiber and other materials and dispersion effect in the composite thereof, eliminate the complicated procedures of forming of raw material post-processed, and the excellent wear resistance of cotton stalk fiber and toughness effectively can improve the mechanical property of matrix material simultaneously.
The preparation technology of described a kind of heat-insulation and heat-preservation composite building material: first in proportion by pearlstone, silicate cement and mineral filler, polystyrene foamed plastics (EPS) and plant fiber powder dry blending, the water adding 18 ~ 25 weight parts after mixing is uniformly mixed, then swelling agent sodium carbonate is added and after stirring rapidly, pour in preprepared model, treat that expansion carries out integer after getting angry, the demoulding after 6-8h, adopt after 30-60h that mechanical means is cut, ground, be processed into the goods of desired shape, size, use after the assay was approved.
The present invention compared with prior art has the following advantages:
1, cost is low.The component adopted is convenient source, compared with existing products in markets, has the advantage of cost.
2, effective.Adopt low thermal conductivity raw material, reach that quality is light, intensity is high, the technique effect that unit weight is low, after tested gained thermal conductivity of composite materials <0.1W/ (MK).
3, environmental protection.The present invention adopts environmental protection raw material, the performance of special interpolation green plants fiber synergistic material, and the pulverizing of EPS waste is directly made heat preserving and insulating material as low density additive and other mixed raw materials by the present invention, make full use of light, the bulky advantage of EPS deal, solve the environmental problem that its ageing-resistant, difficult corrosion brings simultaneously.
