Description
Technical field
The present invention relates to a kind of construction material and preparation method thereof more particularly to a kind of refractory heat-insulating heat-insulating construction material and
Preparation method belongs to architectural decoration paint field.
Background technology
The most directly effective method of building energy conservation is to use heat-insulating heat-preserving material.Do not use fire resistant heat preserving provision for thermal insulation
Building can by wall, window, door, in face, roof and chimney divergence loss energy.It is upper rationally using heat-insulation and heat-preservation material in building
Material, it is possible to reduce the dosage of construction material improves the industrialization degree of construction, accompanied by substantial power saving.
In the prior art, the material used in building is mostly concrete and cement, is easy to pollute the environment, and it is inhaled
Water rate, fire-retardant rate, intensity are all ideal not to the utmost, and also block is heavier, be also easy to produce contraction distortion, heat-insulating property is poor, fragile
It is broken, inconvenient the weakness such as to chop back, influence monolithic architecture quality.
Building exterior wall integral solidified organic heat insulation board and preparation is disclosed in the Chinese patent of Patent No. CN102417327A
Plate and preparation method thereof, be by perlite, Portland cement, white lime, flyash, coarse whiting, aluminium sulfate, zeolite powder,
Acrylic acid, water form according to a certain percentage, and promote solidifying, membrane, maintaining process system by dispensing, dry-mixed, wet mixing, die casting, microwave
Finished product is obtained, defect is：1. big using material contents such as cement, flyash（50% or so）, make obtained thermal insulation thermal insulation board
Density it is big, limit the raising of heat-proof quality；2. needing the techniques such as microwave irradiation, preparation process and need condition complex,
It is unfavorable for the popularization of industrialized production and high value added product.
