Abstract

The invention discloses heat preserving cotton. The cotton consists of the following components in part by mass: 460 to 485 parts of glass cullet, 70 to 75 parts of feldspar, 70 to 95 parts of borax, 45 to 50 parts of calcined soda, 17 to 20 parts of quartz and 80 to 100 parts of cooling material. The invention also discloses a production method of the heat preserving cotton. The heat preserving cotton of the invention has high flexibility, high uniformity, high intensity and uniform surface and does not have pits. The production method discloses by the invention is easy to operate and suitable for industrialized production.

Description

technical field [0001] The invention relates to a thermal insulation cotton, in particular to a light thermal insulation cotton with uniform diameter and a production method thereof. Background technique [0002] As a new fibrous material, thermal insulation cotton has excellent properties such as light weight, heat preservation, fire prevention, sound absorption, moth resistance, and corrosion resistance. It is widely used in chemical industry, metallurgy, light industry, electric power, petroleum and construction industries. At present, the high-quality insulation wool on the market is made of glass wool, but due to the different ingredients of glass wool, the insulation wool made of glass wool has poor flexibility and low strength, and the surface is prone to wrinkles and pits. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies of the prior art and provide a lightweight, flexible, high-strength therm...
