Straw-containing building material as well as preparation method and application thereof

Abstract

The invention discloses a straw-containing building material, as well as a preparation method and application thereof. The building material comprises the following raw materials in parts by weight: 28 to 36 parts of straw, 15 to 25 parts of talcum powder, 33 to 41 parts of a VAE emulsion, 3 to 7 parts of a bamboo vinegar liquid, 11 to 19 parts of potassium permanganate and 5 to 9 parts of manganese acetate. The preparation method comprises the following steps: grinding the straw into powder, performing heating, ultrasonic treatment and centrifugal separation on the straw and the potassium permanganate solution, and taking supernatant liquid to obtain mixed liquid A; adding the bamboo vinegar liquid and the manganese acetate solution, heating and performing ultrasonic treatment to obtain mixed liquid B; adding the potassium permanganate solution and the VAE emulsion into the talcum powder, heating and stirring, performing ultrasonic treatment and centrifugal separation, and taking supernatant liquid to obtain mixed liquid C; and mixing, heating and hermetically stirring the mixed liquid B and the mixed liquid C, and cooling to room temperature to obtain the straw-containing building material. The straw-containing building material can rapidly, efficiently and durably remove formaldehyde, methylbenzene and peculiar smell, has the effects of releasing negative ions and purifyingair, can effectively prevent sulfur dioxide gas and aqueous phase sulfuric acid, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building material containing straw and a preparation method and application thereof. Background technique [0002] Architectural coatings mainly refer to coatings used for building exterior walls, interior walls, ceilings, floors, etc., which have decorative, protective and residential performance improvement functions. Existing furniture, building decoration materials, wall materials and other harmful pollutants seriously exceed the standard, and the quality of indoor air is directly related to the physiological health of the human body. This puts forward higher requirements for the development of interior decoration materials. Traditional common building materials can no longer meet people's needs, and research on materials with healthy environmental functions has become a new direction for the development of building materials. Straw is a renewable resource, whi...

Problems solved by technology

Traditional common building materials can no longer meet people's needs, and research on materials with healthy environmental functions has become a new direction for the development of building materials

Straw is a renewable resource, which is generally burned directly, causing environmental pollution

The utilization of it in the prior art is generally thermal insulation material, and the real utilization rate is low
