Abstract

The invention discloses an environment-friendly rock wool heat-insulation board production process. According to the invention, raw materials are mixed, crushed and preheated, the temperature in a cupola furnace is kept, and liquid oxygen is added when the raw materials are melted and combusted, so that too high heating temperature is not needed during production, the production requirement is reduced, energy is saved, the proportion is reasonable, and it is ensured that the obtained melted raw material liquid is uniform in component; the melted raw material liquid becomes fibrous through centrifugal fiber forming, and a phenolic resin is sprayed in the centrifugal process, so that the generation of slag balls can be greatly reduced; according to the production process, raw materials are crushed through raw material crushing equipment, a mixture is cut and crushed through a crushing roller rotating at high speed, and powder with small particle size is screened out through a screening plate and discharged, so that the obtained mixed raw material is high in uniformity and good in mixing effect, the difficulty of subsequent heating melting and material fibration processes is reduced,the production temperature of the environment-friendly rock wool heat-insulation board is further easily achieved, and the content of slag balls in the environment-friendly rock wool heat-insulation board is reduced.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a production process for an environmentally friendly rock wool thermal insulation board. Background technique [0002] The thermal insulation material can collect excess heat and release it in a timely and stable manner, with small gradient changes, which can effectively reduce the loss. The room temperature can be trended and the winter heat preservation can play a balancing role. Patent No. 201010222393.2 discloses a preparation method of rock wool fiber energy-saving thermal insulation material. Bonding agent and anti-dust oil, and then heated and cured to obtain rock wool fiber energy-saving thermal insulation material products. The key to the inventive method is to recycle the carbon monoxide produced by burning coke in the cupola, and then incinerate it with natural gas to generate a large amount of heat and send it into the cupola again, and then add oxygen to ...
