Preparation method of novel wall building material

Abstract

The invention provides a preparation method of novel wall building material The method comprises the following steps: a) taking straw, a clay material, calcium carbonate, blast furnace slag, feldsparpowder and calcium borate and respectively drying the materials, and performing ball milling; b) taking modified nanocrystalline fiber, modified polystyrene, hydroxypropyl methyl cellulose and butyl rubber, mixing the materials for banburying, after banburying, adding water for stirring, adding a chitosan-containing acetic acid solution and a promoter, placing the materials in a high mixing machine, stirring the materials to obtain a mixture 1; c) mixing mixed powder, the mixture 1 and ammonium polyphosphate, adding water for stirring the materials, and adding an anti-oxidant and a fire retardant drop by drop until addition is completed to obtain a mixture 2; and d) introducing the mixture 2 in a die, performing vibration under room temperature and normal pressure, uniformly dispersing thematerials to form a blank material, drying the blank material, and performing steps of demoulding, maintenance and solidification. The prepared material has the advantages of low heat conduction coefficient, high flame retardation performance, and good stability.

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 wall building material. Background technique [0002] New building materials mainly include five parts: new wall materials, new building coatings, new building plastics, new building decoration materials, and new waterproof and sealing materials. New wall building materials refer to new material resources, low energy consumption, large use of local resources and waste resources; friendly to the environment, people, harmless and conducive to ecological environment protection, maintaining the balance of the ecological environment; at the same time, they can be recycled. New building materials currently have the characteristics of light weight and high strength: light weight mainly means that the material is porous and has a small volume density. High strength mainly refers to the high strength of the material. New wall materi...

Problems solved by technology

At present, single-material thermal insulation materials are restricted by the material itself, and cannot take into account thermal insulation performance, flame retardancy and mechanical properties well.

Inorganic building insulation materials are the earliest building insulation materials developed. This type of material has the advantages of acid and alkali resistance, corrosion resistance, and good stability. However, this type of material has high thermal conductivity, poor thermal insulation performance, and large bulk capacity.

Organic thermal insulation materials are usually porous foam plastics with low density, good mechanical properties and good compressive and tensile toughness, but their decomposition temperature is low, the decomposition heat is large, and they do not have flame retardancy
