Embodiment 1

[0030] Put 40Kg of construction sand, 40Kg of ordinary cement, 5Kg of rare earth-activated inorganic antibacterial agent, and 18Kg of water into the concrete mixer and mix them thoroughly, then add 15Kg of phase change composite materials; stir fully for 2 minutes, mix well and use directly.

[0031] Wherein the phase-change composite material is composed of microcapsules containing phase-change working fluid materials, wherein the phase-change working fluid materials are composed of microcapsules containing 50% octadecane capsule core and 50% melamine-formaldehyde resin capsule wall; The shape of the composite material is as figure 2 The scanning electron microscope photographs are shown.

[0032] The mortar is used in building construction and has a good self-regulating function. After testing, the wall mortar plastering material added with phase-change working fluid materials will not produce macroscopic exudation and hoarfrost within 30 years of use; The fluctuation rang...

Embodiment 2

[0034]Put 50Kg of cement, 35Kg of construction sand, 5Kg of silver zeolite inorganic antibacterial agent, and 25Kg of water into the concrete mixer and mix them thoroughly, then add 10Kg of phase-change self-regulating composite material, and stir for 2 minutes to make self-regulating functional building cement mortar . Wherein the phase change composite material used is to add the microcapsule of weight percent 50% octadecane capsule core and 50% melamine-formaldehyde resin capsule wall, and the appearance of its microcapsule is as follows figure 2 The scanning electron microscope photographs are shown.

[0035] Its technical effect is the same as embodiment one.

Embodiment 3

[0037] Mix 40Kg of quicklime powder, 54Kg of construction sand, 1Kg of rare earth-activated inorganic antibacterial agent, and 20Kg of water, then put them directly into a concrete mixer and mix thoroughly, then add 5Kg of phase-change self-regulating unit particles, and after stirring for 2 minutes, the self- Temperature-regulating functional building mortar. Wherein the phase-change self-regulating temperature unit particles contain 60% by weight of dodecyl alcohol and 40% by weight of sepiolite, and the morphology of the phase-change self-temperature-regulating unit particles is as follows image 3 As shown in the scanning electron microscope photo, the phase transition temperature of the phase transition working fluid material is 24.0°C.

[0038] Its technical effect is the same as embodiment one.

Abstract

The present invention belongs to the field of energy saving building material, and aims at providing one kind of self temperature regulating wall smearing mortar material without effusion and frosting. Technologically, the mortar material consists of phase change composite material 5-15 wt%, building sand 20-50 wt%, agglomerating material 30-50 wt%, and antibiotic mildew preventing agent 1-5 wt% except water. The preparation process includes mixing building sand, agglomerating material, antibiotic mildew preventing agent and water, adding phase change composite material and mixing before applied to the surface of building wall. The present invention has simple production process and low cost, and its use can reduce room temperature change.

Description

technical field [0001] The invention relates to a building wall plastering mortar material, in particular to a self-adjusting temperature building wall plastering mortar material and a preparation method thereof, belonging to the technical field of new energy-saving building material additives. Background technique [0002] The building wall plastering mortar material with self-regulating temperature function is a new type of building material. The working principle of its self-adjusting temperature is as follows: when the ambient temperature is higher than the phase transition point of the material, the phase change material added to the building material absorbs heat from the environment and undergoes a phase transition, reducing the indoor temperature; when the ambient temperature is lower than the phase transition point of the material At the point of change, the phase change material added to the building material undergoes a phase change and releases heat, which increa...
