Abstract

The invention discloses a kind of glass wool for household appliances. The glass wool comprises, by weight, 96-98 parts of centrifugal glass fiber, 2.2-3.8 parts of centrifugal basalt fiber, 1.8-2.2 parts of adhesives and 0.2-0.5 part of water, wherein the centrifugal glass fiber has the heat conductivity coefficient being 0.048-0.052 w / k.m, the fiber diameter being 3.2-4.2 microns, the tensile strength being 22-28 N / cm2, the cotton distribution uniformity being less than or equal to 8.2%, the shot content being less than or equal to 0.15% and the formaldehyde emission rate being zero; the centrifugal basalt fiber has the heat conductivity coefficient being 0.043-0.046 w / k.m, the fiber diameter being 2.8-3.2 microns, the tensile strength being 26-28 N / cm2, the cotton distribution uniformity being less than or equal to 8.2%, the shot content being less than or equal to 0.15% and the formaldehyde emission rate being zero. The glass wool is good in heat preservation and heat insulating effect, low in cost, small in size, safe and non-toxic and completely meets the requirements of household appliances.

Description

technical field [0001] The invention relates to glass wool, in particular to glass wool used in household appliances. Background technique [0002] Commonly used household appliances, such as electric ovens, microwave ovens, and incubators, all need to use thermal insulation materials to keep warm and improve the insulation effect of home appliances. Existing household appliances adopt air insulation, multi-layer tempered glass insulation and extruded board (polystyrene foam), vacuum insulation board, aluminum silicate fiber and the like. Air insulation, multi-layer tempered glass insulation, the thermal insulation effect is poorer than extruded board, vacuum insulation board, aluminum silicate fiber; extruded board has better thermal insulation effect, its thickness is thicker, it will increase the volume of home appliances, and Yi Ran, there is a security risk. However, the cost of vacuum insulation panels and aluminum silicate fibers is too high, which is not conducive ...
