Description

A kind of phase transformation temp auto-controlled cement foaming insulation board and its production method
Technical field
The invention belongs to novel wall material technical fields, and in particular to a kind of phase transformation temp auto-controlled cement foaming insulation board and Its production method.
Background technique
Cement insulation board uses chemical blowing process, and hydrogen peroxide is added to by cement, mineral admixture, water, additional In the slurry that agent, toughened fiber form, foaming in mold is poured into after stirring rapidly, maintenance forms intensity under field conditions (factors) After be cut into porous light heat preservation plate material.
The gentle thermal coefficient of the density of porous, expanded material, heat storage capacity being positively correlated property.To have thermal insulation material There is preferable heat storage capacity, the density of material can be made to increase, so as to cause the increase of thermal coefficient.Therefore, ultralight heat preservation Material often has lower thermal coefficient, and energy storage capability is poor simultaneously.Conventional cement foaming insulation board density is very small, has Lower thermal coefficient thus has preferable heat-proof quality, while heat storage capacity is insufficient.Therefore it is used in China's cold district When have very good heat preservation and energy conservation effects.But in China's hot-summer and cold-winter area in use, itself lower accumulation of heat energy Power makes it very good can not maintain the constant of room temperature under daily cycle warm-natured degree changing environment, causes it at this Energy-saving effect is not significant when a little areas use.
Phase-change material (PCM), which refers to, to be varied with temperature and changes physical property and can provide the substance of latent heat, in the external world During variation of ambient temperature Process of absorption or liberation of heat, itself phase state changes to maintain a certain range of temperature constant state.It is sent out in cement Phase-change material is added in bubble insulation board, can use the accumulation of heat energy that latent heat when phase-change material phase transformation increases cement foaming insulation board Power, so that there is temperature change retardance and temperature ability of regulation and control in ambient temperature cyclically-varying, as a whole, So that the heat storage capacity of thermal insulation material increases so that cement foaming insulation board hot-summer and cold-winter area using when can also show it is excellent Different heat preservation and energy conservation effects.
Summary of the invention
The object of the present invention is to provide have preferable heat storage capacity and meanwhile have a kind of phase transformation compared with low thermal conductivity from Temperature control cement foaming insulation board, in order to realize the purpose, the invention adopts the following technical scheme:
A kind of phase transformation temp auto-controlled cement foaming insulation board of the present invention, it is characterized in that raw material include the group of following weight proportion Point: it is 50~80 parts of cement, 10~30 parts of flyash, 9~12 parts of phase-change material, 30~50 parts of water, 4~8 parts of hydrogen peroxide, early strong Agent, 4~8 parts of alkaline waterproof foam stabilizer, 0.005~0.025 part of regulator, 0.2~0.5 part of toughened fiber.Wherein cement is general Logical 42.5 cement of silicate, toughened fiber is polypropylene fibre, cries the cellulose ether adjusted as 100,000 viscosity, alkaline waterproof foam stabilizing Agent is the ammonium stearate emulsion containing mass fraction 5.25% ammonium stearate and 0.9% potassium hydroxide, and hydrogen peroxide is mass concentration 27.5% industrial hydrogen peroxide.
Include using phase-change material following weight proportion component: it is 3~4 parts of atoleine, 3~4 parts of solid paraffin, swollen 10 parts of swollen perlite.Preparation method are as follows: be added to weight proportion than atoleine, 3~4 parts of solid paraffins for 3~4 parts In 12~14 parts 85 DEG C of hot water, appropriate emulsifier constant temperature stirring 20min is added, and keep the temperature 10min and obtain paraffin wax emulsions.By institute The paraffin wax emulsions produced and 10 parts of expanded perlites are placed in infiltration absorption 20min in vacuum tank and had both obtained required phase-change material.Its Used in expanded perlite be No. 70 expanded perlites.
A kind of production procedure of phase transformation temp auto-controlled cement foaming insulation board is as follows: water, alkaline waterproof foam stabilizer, toughening is fine Dimension, regulator are first placed in stirring in mixing plant, and cement and flyash is then added and phase-change material stirs most homogeneous slurry Then hydrogen peroxide of short duration stirring rapidly is added in material, slurry is poured into mold foaming immediately, and maintenance is extremely formed under natural conditions Demoulding after some strength, cutting can be prepared by a kind of phase transformation temp auto-controlled cement foaming insulation board of the present invention.
The principle of the invention are as follows: what atoleine and solid paraffin were produced, which compound paraffin, has and be suitable for construction material temperature control Transition temperature range.In 20~30 DEG C of range of temperature, there is biggish specific heat capacity and good heat storage capacity, add There are obviously heat preservation and energy conservation effects in energy-saving building materials.When will compound preparation of the paraffin as phase-change material, have It is directly incorporated into, container encapsulation, the modes such as porous material absorption, is seeped wherein directly mixing as method is easy to appear mutually to separate and occur to be precipitated Leakage;Although container package method energy avoids leakage, but increase complicated construction technique degree and cost with higher.Make Not only there are outstanding job stability and anti-exudation stability, Er Qie with porous material such as expanded perlite Adsorption Paraffin Simple process is convenient when use.Studies have shown that taking lotion absorption method that paraffin is adsorbed in expanded perlite than using direct Melting absorption method has higher adsorption capacity and lower leaching rate, and highest adsorption capacity is up to 200%, still, in order to Guarantee that phase change paraffin is not precipitated in expanded perlite, it is zone of reasonableness that maximum adsorption rate, which is no more than 70%,.In this absorption Under rate, it is about 200~250kg/ that phase change paraffin, which is adsorbed on phase-change material apparent density made in No. 70 expanded perlites, m3, close with cement foaming insulation board, a kind of made phase transformation temp auto-controlled cement foaming insulation board material is uniform not stratified.
Compared with prior art, the beneficial effect comprise that be prepared for it is a kind of it is ultralight, thermal coefficient is low, intensity is done Cement foaming insulation board, improve its heat storage capacity so that its in 20~30 DEG C of range of temperature have preferable temperature Retardance and temp auto-controlled ability.
