Embodiment 1

[0021] Embodiment 3: 20 parts of high-density polyethylene, 10 parts of paraffin (C 18 h 36 ), 69 parts of modified calcium carbonate powder with a particle size of 2000 meshes and 1 part of modified metal copper powder were added to the internal mixer together, at 150 o C mixing for 20 minutes; then single-screw extrusion and granulation; finally, three-layer extrusion blow molding to obtain thermal insulation wallpaper base material. DSC test results show that the substrate is 30-35 o C has a phase transition temperature, and the latent heat of phase transition is 30J / g. The product was subjected to cold and hot cycles 200 times (0.8 h each time), and the extravasated paraffin was inserted to remove the extravasated paraffin. The ratio of extravasation was calculated by reducing its mass. The results showed that the ratio of extravasation was 0.2-0.8%.

Embodiment 2

[0022] Embodiment 4: 25 parts of high-density polyethylene, 15 parts of paraffin (C 16 h 34 :C 27 h 56 =1:1), 57 parts of modified calcium carbonate powder with a particle size of 1000 mesh and 3 parts of modified metal aluminum powder with a particle size of 500 mesh were added to the internal mixer together, at 150 o C mixing for 20 minutes; then single-screw extrusion and granulation; finally, three-layer extrusion blow molding to obtain thermal insulation wallpaper base material. DSC test results show that the substrate is 30-35 o C has a phase transition temperature, and the latent heat of phase transition is 40J / g. The product was subjected to cold and hot cycles 200 times (0.8 h each time), and the extravasated paraffin was inserted to remove the extravasated paraffin. The ratio of extravasation was calculated by reducing its mass. The results showed that the ratio of extravasation was 0.2-0.8%.

Embodiment 3

[0023] Embodiment 5: 20 parts of high-density polyethylene, 20 parts of paraffin (C 16 h 34 :C 21 h 44 =1:1), 55 parts of modified calcium carbonate powder with a particle size of 4000 mesh and 5 parts of modified metal iron powder of 500 mesh were added to the internal mixer together, at 150 o C mixing for 20 minutes; then single-screw extrusion and granulation; finally, three-layer extrusion blow molding to obtain thermal insulation wallpaper base material. DSC test results show that the substrate is 30-35 o C has a phase transition temperature, and the latent heat of phase transition is 55J / g. The product was subjected to cold and hot cycles 200 times (0.8 h each time), and the extravasated paraffin was inserted to remove the extravasated paraffin. The ratio of extravasation was calculated by reducing its mass. The results showed that the ratio of extravasation was 0.2-0.8%.

Abstract

The invention discloses padding type thermal insulation wallpaper and a preparation method thereof. The padding type thermal insulation wallpaper is characterized by comprising three layers, wherein an innermost layer which is a wallpaper base material with 150-400 microns in thickness is a thermal insulation layer of the wallpaper made of 25-40 parts of a shape-stabilized phase change material (polyolefin and paraffin), 55-70 parts of calcium carbonate powder and 1-5 parts of metal powder; a middle layer is a water-soluble coating layer; and an outermost layer is a printing layer. The wallpaper is thermal insulation wallpaper which is environment-friendly, ecological and healthy and is particularly suitable for the demand of indoor decoration.

Description

Technical field: [0001] The invention belongs to the fields of energy saving, environmental protection and decorative materials, and in particular relates to a novel temperature-adjustable wallpaper and a preparation method thereof. Background technique: [0002] With the energy crisis and changes in the world's energy pattern, as well as people's increasing demand for energy, how to use energy efficiently and rationally, create a healthy, comfortable, and energy-saving working environment, and develop building energy-saving technologies has attracted worldwide attention. At present, the measures to keep the living environment warm in winter and cool in summer are still achieved through one-way consumption of energy, such as using air conditioners to cool down in summer, and using coal, natural gas, and electric heating in winter. Coal-burning not only has low heat utilization efficiency, but also causes serious air pollution; natural gas heating is convenient but expensiv...
