Embodiment 1

[0009] (1) Weigh corn stalks, carbon fiber, sulphoaluminate cement, aluminum sol, phenolic resin and fly ash according to the ratio of 20%: 15%: 20%: 12%: 2%: 1% to obtain the mixture ;

[0010] (2) Put the mixture into the mixing tank and stir, the mixing tank stirring speed is 300 rpm, and the stirring time is 50 seconds;

[0011] (3) Add tap water in proportion, stir with a foaming machine to obtain fine and uniform foam, after standing still, add naphthalene-based water reducer and stir, and use mechanical extrusion blooming method or manual blooming method to make a wet billet; thereafter After drying and cutting, the plant fiber building insulation material is obtained.

Embodiment 2

[0013] (1) Weigh corn stalks, carbon fiber, sulphoaluminate cement, aluminum sol, phenolic resin and fly ash in proportions of 30%: 20%: 30%: 12%: 5%: 3% to obtain a mixture ;

[0014] (2) Put the mixture into the mixing tank and stir, the mixing tank stirring speed is 500 rpm, and the stirring time is 80 seconds;

[0015] (3) Add tap water in proportion, stir with a foaming machine to obtain fine and uniform foam, after standing still, add naphthalene-based water reducer and stir, and use mechanical extrusion blooming method or manual blooming method to make a wet billet; thereafter After drying and cutting, the plant fiber building insulation material is obtained.

Abstract

Plant fiber building insulation materials, including: plant fiber, carbon fiber, sulphoaluminate cement, aluminum sol, phenolic resin and fly ash are weighed in proportion and put into a mixing tank for stirring, and then water is added in proportion to The foaming machine is stirred, and after standing still, the water reducing agent is added to stir, and the wet billet is obtained by mechanical extrusion blooming method or manual blooming method; after that, it is dried, and the plant fiber building insulation material is obtained after cutting. The insulation wall material provided by the invention effectively utilizes wood, bamboo and crop straw resources, improves the environment, and reduces costs; at the same time, the obtained insulation wall material has light weight, resistance to drying shrinkage, good stability, and effectively reduces the brittleness of foam concrete , and can maintain its advantages of low density, good thermal insulation performance, good sound insulation effect, and adjustable indoor humidity.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to plant fiber building thermal insulation materials. Background technique [0002] Measures to reduce the indoor heat dissipation of buildings to the outside play an important role in creating a suitable indoor thermal environment and saving energy. At present, my country's thermal insulation materials are mainly polystyrene, which accounts for 99% of the existing thermal insulation materials. However, polystyrene, as an insulation material, has very serious safety hazards. However, wood, bamboo and crop straws are characterized by softness and cotton, good toughness and good thermal insulation performance. Therefore, it is of great significance to use wood, bamboo and crop straws to develop new wall materials and to turn rice straw waste into treasure. Market potential. Contents of the invention [0003] In order to solve the above technical problems, the ...
