Method for preparing novel energy-saving heat-insulating material

Abstract

The invention provides a method for preparing a novel energy-saving heat-insulating material. The method comprises the following preparation steps: a. mixing bentonite, slag, fly ash, quartz sand anda common-salt aqueous solution, and carrying out uniform stirring, so as to obtain slurry I; b. mixing fibers, polystyrene foamed particles, water glass, redispersible latex powder, a foamer, a foam stabilizer and water, and carrying out a foaming reaction, so as to obtain slurry II; c. slowly stirring the slurry II, carrying out defoaming, then, carrying out filtering, and removing solid particles, so as to obtain slurry III; and d. mixing the slurry I and the slurry III, adding calcium carbide, a water reducing agent, titanium dioxide, chitosan and hollow glass beads, carrying out high-temperature pressurizing, carrying out high-speed stirring, then, injecting the mixture into a twin-screw extruder, carrying out melting and extruding, then, introducing the extruded substance into a mold,carrying out limited pressurizing, and carrying out curing, thereby obtaining the novel energy-saving heat-insulating material. The material prepared by the method is wide in source and low in cost,and the preparation method is easy in operation and is applicable to industrial large-scale production manufacturing.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a novel energy-saving thermal insulation material. Background technique [0002] my country's construction market is getting bigger and bigger, and building energy consumption is also getting higher and higher. If no energy-saving measures are taken, it will bring huge losses to the economy and energy. Building energy conservation has become one of the important strategies for sustainable energy development today. Therefore, building energy conservation must be coordinated with social and economic sustainable development and ecological environment protection. Focus on research and development in areas such as recyclability. [0003] Thermal insulation is to reduce heat loss, improve energy utilization, and ultimately achieve the goal of energy conservation. The development and progress of thermal insulation materials will help promo...

Problems solved by technology

[0003] Thermal insulation is to reduce heat loss, improve energy utilization, and ultimately achieve the goal of energy conservation. The development and progress of thermal insulation materials will help promote the implementation of energy-saving projects, meet the needs of national economic development for energy, and protect the national economy. Building a healthy and stable development has great social and economic significance. Therefore, it is necessary to vigorously develop the thermal insulation material industry and widely adopt high-quality thermal insulation materials. This is of great practical significance to the healthy and stable development of economic construction. As of now In other words, traditional heat insulation materials such as foam glass, calcium silicate, expanded pearl wool, glass fiber products, polyurethane and expandable polystyrene boards are still widely used in the market, and the thermal conductivity of these materials is generally relatively low. At the same time, some materials still have problems such as flammability and smoke toxicity
