Description
Technical field
The present invention relates to energy-saving and heat-insulating material technical field, be more particularly to added with diatomaceous compound insulating material and its
Preparation method.
Background technology
At present in the world, energy problem has turned into a prominent contradiction.China makes the energy because of rapid economic development
Contradiction with environmental issue is more protruded.China is currently construction market maximum in the world, and annual increasing newly there are about 2,000,000,000 m2Build
Build, wherein 95% above is high energy consumption is built, if not taking conservation measures, there will be 50% consumption in building to the year two thousand twenty whole nation energy
On, massive losses will be brought to national economy and the energy.
The main purpose of building energy conservation is to reduce energy resource consumption, while reducing environmental pollution.Government is in succession with law and text
The form of part has put into effect special policy, promotes Building Energy-saving Work, building energy conservation to turn into China's energy sustainable development energetically
Strategic decision.Therefore building energy conservation must develop in harmony with Sustainable Socioeconomic Development, ecological environmental protection etc., and this just promotees
People are made for the thermal and insulating performance of construction material, practical value, the stability of material and service life, technology
The aspects such as reliability, eco-environmental prote and reusable edible carry out primary study and exploitation.
The building energy-saving heat-insulating material that China is used at this stage mainly has following a few classes：（1）Inorganic heat insulation material, with rock
It is the insulation material for growing up at first based on cotton, mineral wool and expanded perlite, building energy conservation heat insulation is served positive
Effect.Inorganic heat insulation material acid and alkali-resistance, it is corrosion-resistant, do not ftracture, do not fall off, stability it is high, in the absence of problem of aging, with building wall
The body same life-span.Easy construction, it is applied widely, it is adaptable to the insulation of various wall basic units material and variously-shaped complicated wall.
And totally-enclosed, seamless, without cavity, there is no cold-heat bridge to produce.External wall outer insulation can not only be done can also do exterior wall insulating
Temperature, or exterior wall is inside and outside while insulation and the thermal insulation layer of underground heat on insulation and roof.Fire protection flame retarding security is good, can be widely used for
Intensive house, public building, large-scale public place, combustible and explosive area, to the strict place of fire protection requirement.It is alternatively arranged as fire prevention
Isolation belt construction, improves Building Fire Protection standard.But there is following major defect simultaneously：Poor thermal insulation property, floor space are big；It is anti-
Clash into and compressive strength is poor；Hygroscopicity is big, environmental-protecting performance is poor, harmful in construction and application.（2）Polyurethane PU hard bubbles
Energy-saving and heat-insulating material, is a kind of inorganic at present and minimum material of organic insulation material thermal conductivity factor.Reaching same heat-insulated effect
Under the conditions of fruit, the insulation material thickness that it is used is minimum.PU hard bubbles in hole-closing structure, and rate of closed hole is up to more than 95%, with excellent
Waterproof, vapor-proof performance, can intercept water and vapor permeation makes wall keep a good stable adiabatci condition, this is current
The advantage that other insulation materials do not possess.The polyurethane PU energy-saving and heat-insulating material that hard bubbles has certain toughness, is not likely to produce cracking
Phenomenon, impact resistance is excellent, the ability with stronger resistance external force.But environmentally friendly, the fire-retardant and smoke elimination of home products
Can be unqualified, a large amount of dense smokes are also easy to produce in burning, cause casualties.Several domestic fire make one to hard polyurethane foam
The fire protecting performance of energy-saving and heat-insulating material produces worry, and some local even regulations mustn't be used in high-rise and public place building should
Material.（3）Polystyrene foam heat insulation material, the current organic foaming kind insulation material of China's building energy conservation has polystyrene block
EPS, extruded polystyrene board XPS, spraying polyurethane SPU and granular polystyrene etc., auxiliary material are polymer bonding mortar, interface processing
Agent or boundary mortar, special swell fixture, alkali-resistant glass fiber mesh and galvanized steel wire netting etc..The construction work of plastic plate class insulation material
Skill is usually first glued and follows closely afterwards, interface processing or special treating agent, paste net, smear anticracking grout etc..Organic insulation material has weight
Gently, processability is good, compactness is good, good effect of heat insulation the characteristics of.Polystyrene foam heat insulation material is a kind of thermoplastic
Property material, it is more superior than inorganic heat insulation material performance, but its some shortcomings are gradually exposed in use：Polyphenyl second
Alkene insulation material has cavity structure, and outside air influences heat insulation effect easily by gap in Cavity Flow；Taking off property of wind resistance is poor：
EPS tensile strength under dry condition, only 0.1 Mpa, the tensile strength after immersion is lower, thus EPS is generally not used for height
Layer building；Polystyrene heat insulation material requirement storage could be used to construct after 40 days, be difficult to accomplish in practice, so using
Easily there is crack, wall moisture-inhibiting and returns water phenomenon in the engineering of EPS insulations.Polystyrene heat insulation material is mostly sent out using freon
Bubble, easily causes atmosphere pollution, and molten drop is produced under the fiery high temperature of chance, second-time burning easily occurs and with the flame propagation velocity being exceedingly fast.
Therefore public place and skyscraper must be careful using such insulation material.（4）Compound material, refers to using treated agriculture
Crop straw, the rubbish with heat-insulating property and through harmless treatment and the hollow material produced by technological means such as foaming
Deng.The good effect of heat insulation of composite, it has the lot of advantages of inorganic material：Fire protection flame retarding, deformation coefficient are small, anti-ageing
Change, stable performance, good eco-environmental prote, heat-insulation layer intensity high, long service life, difficulty of construction are small, the low advantage of engineering cost,
And its raw material sources is extensive, energy consumption is low, can economize on resources, the cycling and reutilization rate of resource is improved.But composite is still
In the stage of development, without the marketization.Additionally, the heat insulating material for growing up such as insulating moulding coating, radiation proof
Coating etc., these materials have certain heat insulating effect, are also had made some progress using upper, but its performance and application are above deposited
In limitation：One is relatively costly, and two is fast coating aging, and service life is limited.
In sum, energy-conservation in the market
Insulation material also has many shortcomings in using effect, and the application to above-mentioned material brings many restrictions so that
Building is integrally unable to reach preferable quality level, while also the realization to building energy conservation overall goal brings no small choosing
War.
