A kind of self temperature regulating phase-change energy storage heat-insulating decorative composite board
Technical field
The present invention relates to building material field, it is specifically related to a kind of self temperature regulating phase-change energy storage heat-insulating decorative composite board and preparation method.
Background technology
Along with our people's growth in the living standard, people are also more and more higher to the requirement of building board, no matter from the performance of outward appearance or material itself. The particularly north, along with entering winter or season in the early spring, indoor heat is distributed to outdoor easily via metope, thus reduces indoor temperature.
Building heat preservation is the measure that minimizing Indoor environment heat distributes to outdoor, and the indoor thermal environment suitable to creation and save energy play an important role. Building heat preservation is mainly taken measures from building external envelope structure, reduces the measure that Indoor environment heat distributes to outdoor simultaneously, and the indoor thermal environment suitable to creation and save energy play an important role.
Tradition lagging material only has single resistive properties, it does not have energy-saving and temperature-regulating function, and has absorption or the performance of release energy in the change process of other forms due to phase change material, therefore obtains widely using of construction industry energy-saving field.
Summary of the invention
First object of the present invention is to provide a kind of self temperature regulating phase-change energy storage heat-insulating decorative composite board, comprises thermal insulation layer, adhesive linkage and ornament layer. Wherein, thermal insulation layer is bonded as one by adhesive linkage and ornament layer.
Preferably, thermal insulation layer is self temperature regulating phase-change energy storage warming plate, and adhesive linkage is urethane glue-line, and ornament layer is aluminium-plastic panel, any one of calcium silicate board with microporous or cement fibrolite plate.
Thermal insulation layer is made up of the raw material of following weight part: perlite 20 ~ 40 parts, 15 ~ 25 parts, calcium powder, 5 ~ 10 parts, paraffin, white carbon black 5 ~ 15 parts, inorganic salt minerals matter fiber 10 ~ 18 parts, 4 ~ 8 parts, urea, acid amides 6 ~ 12 parts.
Inorganic salt minerals matter fiber described in the present invention is any one in aluminum silicate fiber, slag coal fiber, sepiolite fibre.
Preferably, above-mentioned self temperature regulating phase-change energy storage lagging material is made up of the raw material of following weight part: perlite 36 parts, 18 parts, calcium powder, 12 parts, paraffin, white carbon black 10 parts, inorganic salt minerals matter fiber 15 parts, 3 parts, urea, acid amides 10 parts.
The method preparing self temperature regulating phase-change energy storage heat-insulating decorative composite board is as follows:
A) preparation of self temperature regulating phase-change energy storage warming plate:
By perlite, calcium powder, paraffin, white carbon black, inorganic salt minerals matter fiber, urea, acid amides, adds water at stirred pot and stirs 1h until after mixing, being poured into by slurries in mould, use doctor blade aftershaping. By the demoulding after maintenance 72h in standard curing box of the lagging material of forming, then maintenance obtains self-temperature-adjusting phase change lagging material after 5 days in standard curing box, and the relative humidity of maintaining box is 98, and temperature is 25 DEG C.
B) with the molten glue of urethane by fixing to the above-mentioned self temperature regulating phase-change energy storage warming plate for preparing and aluminium-plastic panel, calcium silicate board with microporous or cement fibrolite plate bonding.
In the present invention, the content of the water described in self temperature regulating phase-change energy storage lagging material preparation method to be enough to make the moistening one-tenth slurry of the raw material of making self temperature regulating phase-change energy storage warming plate.
Product of the present invention is both artistic and practical, and preparation method is simple, and material is easily buied, it may also be useful to effect is positive.
Embodiment:
Below in conjunction with concrete case study on implementation, the present invention is described in further detail:
Embodiment 1:
The making method of self temperature regulating phase-change energy storage heat-insulating decorative composite board comprises the step of following order:
A) making of warming plate:
By perlite 40kg, calcium powder 25kg, paraffin 10kg, white carbon black 15kg, aluminum silicate fiber 18kg, urea 8kg, acid amides 12kg, add water at stirred pot and stir 1h until after mixing, being poured into by slurries in mould, use doctor blade aftershaping. By the maintenance demoulding after 3 days in standard curing box of the lagging material of forming, then maintenance obtains self-temperature-adjusting phase change lagging material after 5 days in standard curing box, and the relative humidity of maintaining box is 98, and temperature is 25 DEG C. Wherein, base-material: water=1:1.5(mass ratio).
B) with polyurethane adhesive, the above-mentioned self-temperature-adjusting phase change warming plate for preparing and aluminium-plastic panel are bonded as one. Obtain self temperature regulating phase-change energy storage heat-insulating decorative composite board.
Embodiment 2:
A) by perlite 35kg, calcium powder 25kg, paraffin 10kg, white carbon black 10kg, aluminum silicate fiber 15kg, urea 8kg, acid amides 10kg, add water at stirred pot and stir 1h until after mixing, being poured into by slurries in mould, use doctor blade aftershaping. By the maintenance demoulding after 3 days in standard curing box of the lagging material of forming, then maintenance obtains self-temperature-adjusting phase change lagging material after 5 days in standard curing box, and the relative humidity of maintaining box is 98, and temperature is 25 DEG C. Wherein, base-material: water=1:1.2(mass ratio).
B) with polyurethane adhesive, the above-mentioned self-temperature-adjusting phase change warming plate prepared and colored calcium silicate board with microporous are bonded as one. Obtain self temperature regulating phase-change energy storage heat-insulating decorative composite board.
