Embodiment Construction

[0018] The paraffin wax phase-change thermal insulation mortar powder of the present invention comprises 35-75% of cement, 5-40% of lightweight aggregate and 0.5-10% of fiber, and is characterized in that it also contains 5-40% of paraffin in the proportioning ratio.

[0019] The above-mentioned paraffin is natural paraffin, synthetic paraffin or a mixture of natural paraffin and synthetic paraffin, including one or more of beeswax, butter, stearic acid, and low melting point asphalt.

[0020] The ratio range calculated by weight is:

[0021] Paraffin (5~40)%,

[0022] Cement (35~75)%,

[0023] Fiber (0.5~10)%

[0024] Foaming agent (0.05~0.15)%

[0025] Polystyrene particles (5~40)%.

[0026] The above-mentioned lightweight aggregate is polystyrene particles, expanded perlite, expanded vermiculite, ceramsite, rubber particles, or a mixture of two or more of the above-mentioned lightweight aggregate particles.

[0027] The above-mentioned fibers are inorganic fibers or or...

Abstract

A mortar powder containing paraffin wax for phase-change insulating is prepared from cement, light aggregate, fibres and paraffin wax through fusing paraffin wax or preparing the microcrystal powder of paraffin wax, and proportionally mixing it with others. Its advantages are low hydroscopicity and high water-proof performance and softening coefficient.

Description

technical field [0001] The invention relates to a thermal insulation mortar and a preparation method thereof. Background technique [0002] Existing thermal insulation mortar generally contains cement, lightweight aggregate and fiber, and has defects such as high water absorption, poor water resistance, low softening coefficient, and water resistance, so the construction is greatly affected by the weather. Contents of the invention [0003] The invention provides a paraffin phase-change thermal insulation mortar powder and a preparation method of the paraffin phase-change thermal insulation mortar, which solves the technical problems of high water absorption, poor water resistance, low softening coefficient and water resistance of the existing thermal insulation mortar. [0004] The technical scheme of the paraffin wax phase-change thermal insulation mortar powder of the present invention: it includes 35-75% of cement, 5-40% of light aggregate and 0.5-10% of fiber, and is ...
