Heat insulation structure for electric appliance and preparation process of heat insulation structure

Abstract

The invention discloses a thermal insulation structure for electrical appliances and a preparation process thereof. The structure comprises an upper fireproof cloth layer and a lower fireproof cloth layer, hemming layers are sewn on the edges of the upper fireproof cloth layer and the lower fireproof cloth layer, and the space between the upper fireproof cloth layer and the lower fireproof cloth layer is filled with a superfine glass fiber cotton layer. Compared with a traditional household appliance product, the heat insulation effect is better, the production efficiency is higher, the upper fireproof cloth layer and the lower fireproof cloth layer which are made of the superfine glass fiber cotton layer, the fireproof heat insulation dewaxing cloth are sewn together through fireproof threads, hems are included, internal glass fibers can be fixed to one position, the superfine glass fiber cotton layer cannot move in the transportation process of finished products, the heat insulation effect is better, the heat insulation performance is higher, production is conducted through a machine in the manufacturing process, limbs of people cannot touch glass fibers, the burden of manual finished product production can be relieved, production operation pains are reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of electrical insulation, and more specifically relates to an electrical insulation structure and a preparation process thereof. Background technique [0002] Thermal insulation materials, materials that can block heat flow transfer, also known as thermal insulation materials, traditional thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., new thermal insulation materials, such as airgel felt, vacuum panels, etc. Heat insulation materials are often used in electrical appliances, but the heat insulation structures used in existing electrical appliances have the following deficiencies. [0003] At present, the effect of heat insulation materials used in traditional home appliances is not ideal, and the internal heat insulation materials will move during the transportation of products, which will affect the effect of heat insulation. The heat cannot be completely blocked during use, wh...

Problems solved by technology

[0003] At present, the effect of heat insulation materials used in traditional home appliances is not ideal, and the internal heat insulation materials will move during the transportation of products, which will affect the effect of heat insulation. The heat cannot be completely blocked during use, which greatly reduces In addition, the heat insulation production of traditional household electrical appliances requires manual operation during production, that is, touching ultra-fine glass fiber with hands and filling it into the heat insulation step, which is inefficient. In addition, due to the direct contact of ultra-fine glass The skin will feel itchy, reducing the efficiency of production
