Building external wall fireproof and thermal insulation material and preparation method thereof

Abstract

The invention provides a building external wall fireproof and thermal insulation material and a preparation method thereof. The material is composed of the following components by weight: 70-90 parts of Portland cement, 30-50 parts of a waste molecular sieve catalyst, 8-15 parts of nano calcium carbonate, 5-8 parts of carbon fiber, 10-15 parts of water glass, 1-3 parts of a water reducing agent and 18-36 parts of water. The building external wall thermal insulation material provided by the invention can save cement consumption and reduce the engineering cost, also can reduce environmental destruction, and improves the compressive strength and fireproof and thermal insulation performance of the material.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fireproof and thermal insulation material for building exterior walls and a preparation method thereof. Background technique [0002] In my country, building energy consumption has become one of the three major energy consumers together with industrial energy consumption and transportation energy consumption. The energy-saving potential is huge. The building energy-saving industry has become an important organic part of the energy-saving and environmental protection industry. Building energy conservation is mainly accomplished through two aspects, one is to reduce building energy consumption, and the other is to improve the energy utilization efficiency of building energy consumption systems. The use of thermal insulation building materials is the main way to achieve building energy conservation. In the building energy-saving system, the heat loss of the...

Problems solved by technology

However, this kind of component is usually suitable for making doors, door frames and window frames, and it is not universally applicable to replace walls, and the market is difficult to accept

Because it is light in weight, poor in sound insulation, not high enough in strength, and even poor in connection with other accessories. For example, it is difficult to nail or punch holes in such a wall, so it can only be pre-embedded during casting.
