Glass wool for dry vacuum insulated panel core material and production method thereof

Abstract

The invention discloses a glass wool for a dry vacuum insulated panel core material and a production method thereof. The production method comprises the following steps of mixing the following components in parts by mass to form a mixture: 10.0-40.0 parts of quartz powder, 10.0-12.5 parts of feldspar, 9.0-11.0 parts of sodium borate, 1.5-3.5 parts of calcspar, 2.5-7.0 parts of dolomite, 7.0-15.0 parts of sodium carbonate and 15.0-60.0 parts of plate glass; adding the mixture into a melting tank of a kiln to melt and prepare vitreous humour; putting the vitreous humour into a bushing well and a centrifugal plate, and conveying to a centrifugal machine to spin and prepare the glass wool. The glass wool disclosed by the invention can be directly prepared into the dry vacuum insulated panel core material. Compared with the insulated panel core material produced by a wet process, the glass wool is short in production flow; and wet pulp is prepared without adding water or baking. Therefore, the production efficiency is improved; the energy source is greatly saved; the price of the insulated panel is reduced, and strong popularization and use of the market are facilitated.

Description

[0002] The dry-process vacuum insulation panel with ultra-fine glass wool as the core material is the best cost-effective A-level inorganic non-combustible material among the known solid insulation materials. It has a broad application market in thermal insulation and barrier. It is mainly used in refrigerators, Freezers, refrigerated containers, freezers, medical cold preservation equipment, vending machines and other facilities and equipment can efficiently and conveniently achieve energy saving and cold preservation effects. In China, the application is not yet widespread, and the combustion level of existing organic materials cannot reach Class A. The production process of the core material made by a small amount of wet method requires adding water to make pulp, then laying boards to filter and remove water, then dehydrating, and finally drying at high temperature to reduce the water content to less than 0.4%, and then cutting. The production process consumes a lot of energy. Amplitude increase
