A kind of lightweight vitrified microbead insulation material reinforced by cellulose derivatives and its preparation method

Abstract

The invention discloses a light-weight vitrified microbead thermal insulation material reinforced by cellulose derivatives and a preparation method thereof. The raw materials used in the preparation of the light-weight vitrified micro-bead thermal insulation material reinforced by cellulose derivatives are calculated by weight percentage, and the ratio is 1.9- 2.7% sodium carboxymethyl cellulose, 36.0-50.3% glass microspheres, 7.2-10.1% glass fiber and the balance is water. The preparation method is to first mix and stir sodium carboxymethyl cellulose and water until a viscous liquid is formed Add glass microspheres and glass fibers into the container, then add the obtained viscous liquid, stir and mix evenly, put the obtained mixture into a mold, compact and form it, demould it, and then dry it at a temperature of 90-100°C to obtain a The light-weight vitrified microbead insulation material reinforced by cellulose derivatives with the characteristics of low density, excellent thermal insulation performance and high mechanical strength has low production cost, simple preparation process and no special equipment, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a light-weight vitrified microbead thermal insulation material reinforced by cellulose derivatives and a preparation method thereof, belonging to the field of thermal insulation materials. Background technique [0002] With the depletion of the traditional three major fossil energy sources, energy conservation and environmental protection have become an increasingly hot topic. At present, my country's building energy consumption has risen sharply year by year, reaching 45% of the country's total energy consumption, which has caused a huge burden on the development of the national economy. Therefore, building energy saving is imminent. Maintaining the temperature inside the building and reducing its heat loss is an effective way to improve the energy efficiency of the building. At present, the insulation materials used in more than 80% of domestic buildings are mainly organic materials such as expanded polystyrene board (EPS),...
