Abstract

The invention discloses a heat absorbing material for a heat insulating box. The heat absorbing material is characterized by being prepared from the following raw materials in parts by weight: 10-20 parts of polyvinyl alcohol, 50-60 parts of chlorinated paraffin, 2-4 parts of water-absorbent resin, 1-2 parts of monopotassium phosphate, 3-4 parts of methyl nylon acid, 1-2 parts of alum powder, 1-2 parts of locust bean gum, 0.3-1 part of trichloroisocyanuric acid, 1.3-2 parts of graphite powder, 0.5-1 part of potassium titanate whisker, 0.4-1 part of dodecyl trimethyl ammonium chloride and 0.1-0.2 parts of hexamethyl phosphoric triamide. The material of the heat insulating layer disclosed by the invention is long in service life, recyclable, strong in heat absorbing effect, environment-friendly, free from corrosion on both internal and external walls and good in high temperature resistance. The heat absorbing material disclosed by the invention can be used for reducing temperature rise speed by enhancing external heat insulating capacity and internal heat absorbing capacity, so that the heat absorbing material can be used for protecting required objects within relatively long time.

Description

technical field [0001] The invention mainly relates to the field of heat preservation, in particular to a heat absorbing layer material for a heat preservation box. Background technique [0002] At present, humans cannot produce materials that are absolutely insulated. Put a closed box in a high-temperature environment, and the heat will continue to conduct into the box, so that the temperature inside the box will continue to rise until the temperature difference between the inside and outside disappears. The invention reduces the speed of temperature rise by increasing the heat insulation capacity of the outer layer and the heat absorption capacity of the inner layer, thereby protecting objects to be protected in a relatively long period of time. Contents of the invention [0003] The object of the present invention is to provide a heat absorbing layer material for a thermal insulation box. [0004] The present invention is achieved through the following technic...
