Embodiment 1

[0021] figure 1 It is a DSC curve diagram of a microcapsule phase change material with a phase transition temperature of 27°C, and its DSC curve is measured by an American MDSC 2910, TA Instruments type DSC tester. Such as figure 1 As shown, the peak endothermic temperature of the microcapsule phase change material is 27.67°C, and the total endothermic value is 96.74J / g, indicating that the material is a microcapsule phase change material with a phase change temperature of 27°C at room temperature. The capsule phase change material is a commercially available product, which is selected according to the phase change temperature. The particle size is selected as 2-7μm, and the endothermic and exothermic properties are as follows: figure 1 The shown aqueous solution containing 35% microcapsule phase change material is mixed with polyurethane screen printing adhesive at a ratio of 1:4, the mixture is dried and solidified at 120°C for 60 minutes, and the microcapsule phase change...

Embodiment 2

[0023] At room temperature, mix the microcapsule phase change material powder with a phase change temperature of 31°C, a particle size of 2-7 μm, and an endothermic heat of 158.7 J / g with an epoxy resin screen printing adhesive at a ratio of 4:5, and the mixture is heated at 230 Dry and solidify at ℃ for 5 minutes, and apply the microcapsule phase change material to the cotton cloth by embellishing silk screen printing technology. 40%.

Embodiment 3

[0025] At room temperature, mix the aqueous emulsion containing 10% microcapsule phase change material with a phase change temperature of 0°C and a particle size of 2 to 7 μm with an acrylic resin screen printing adhesive at a ratio of 1:9, wherein the microcapsule phase change material solution contains 48% aqueous solution of microencapsulated phase change material powder. The mixture was dried and solidified at 30°C for 120 minutes, and the microcapsule phase change material was coated on the packaging plastic cloth by dotted silk screen printing technology, in which the shape surface pattern was a cross star with a length and width of 6 mm and a height of 1 mm, containing micro Capsule Phase Change Material 3%.

Abstract

The present invention discloses a preparation method of textile cloth containing microcapsule phase change material and packaging material. Said preparation method includes the following steps: mixing microcapsule phase change material powder body or water emulsion and thermosetting adhesive according to the mixing ratio of 1:0.5-9 at normal temperature; drying and solidifying mixture for 3-120 min, at 30-300 deg.C; then utilizing dotted screen printing technique to make the microcapsule phase change material be coated on the cloth or packaging material to form coating layer with plastic pattern, in said coating layer the content of microcapsule phase change material is 3%-70%. The cloth or packaging material produced by the invented process has good heat-absorbing property, so that it has extensive application.

Description

technical field [0001] The invention relates to the technical field of application of microcapsule phase change materials in chemical industry, textile industry and packaging industry, in particular to a preparation method of textile cloth and packaging materials containing microcapsule phase change materials. Background technique [0002] Microcapsule phase change materials refer to synthetic polymer materials composed of microcapsule core materials and micro- or nano-scale microcapsule shells. The shell materials can withstand high and low temperatures and are not affected by temperature changes. The microcapsule core materials are phase change materials. Organic matter with temperature change from -50 to 150°C. The phase change temperature range of microcapsule phase change materials is between -50 and 150°C, and its heat absorption and heat resistance properties are determined according to the phase change temperature of the core material. Polym...
