Abstract

The invention discloses a heat insulation material, comprising 25-40% of glass fiber, 20-35% of methylcellulose solution, 3-10% of mixture of vinyl acetate and ethylene copolymer, 5-10% of bentonite, 3-10% of vermiculite, 1-5% of foaming agent and 25-35% of thermosetting amino resin. The invention further discloses a method for preparing a heat insulation shell from the heat insulation material, which comprises the following steps of: adding the materials into a blender mixer to be uniformly blended and stirred, then adding into a high-speed cutting machine to obtain a sludge object, adding the sludge object into a mold, which is heated to 180-280 DEG C, according to the weight of each style of product, pressure casting, keeping pressure for 2-3m to obtain the heat insulation shell. The heat insulation shell has the advantages of good energy-saving effect, easy formation and attractive appearance.

Description

technical field [0001] The invention belongs to the technical field of heat insulation materials, in particular to a heat insulation material used for household appliances and a method for preparing a heat insulation shell using the material. Background technique [0002] With the deterioration of the human living environment and the warming of the temperature, many countries have incorporated energy conservation and emission reduction into the national strategy, and the refinement of environmentally friendly products has gradually become a trend. At present, in the field of heat insulation materials, it has become the direction for enterprises to enhance their competitiveness by improving the heat insulation effect, reducing costs, and improving the convenience of use to increase the added value of products. In the prior art, there is a method of using air to improve the heat insulation effect, but because the existence of air reduces the compression resistance and flexibil...
