Embodiment 1

[0025] Add 4 / 5 tank capacity of magnesium chloride solution with a concentration of 20% and a temperature of 25 degrees Celsius in the mixing tank of the cement mortar mixer, then add 2 / 3 tank capacity of plant fiber and stir for 5 minutes to degrease, then add the weight of plant fiber 45% of the amount of fly ash with a mesh number of 300 mesh was stirred for 5 minutes to fill the holes, and then an aqueous sodium methyl silicate solution with a weight of 1:20 accounting for 30% of the amount of the fly ash was added and stirred for 5 minutes to gel; After the gelling treatment, the plant fibers are taken out and drenched to make the water content 35%, and then put into the air-flow dryer for drying, so that the water content is 5%, and then made into particles with a fineness of 80 meshes to form the Inorganic light-weight filler aggregates of plant fibers are put into inner membrane waterproof bags for later use.

Embodiment 2

[0027] In the mixing tank of the cement mortar mixer, add 4 / 5 tank capacity of magnesium chloride solution with a concentration of 20% and a temperature of 28 degrees Celsius, add 2 / 3 tank capacity of plant fiber and stir for 5 minutes to degrease, then add the weight accounted for the amount of plant fiber. 47%, the mesh number is 330 mesh fly ash and stirs for 5 minutes to fill the holes, then add 1:20 weight accounted for 33% sodium methyl silicate aqueous solution of the amount of the fly ash and stir for 5 minutes to gel; After the gelling treatment, the plant fibers are drenched to make the water content 35%, and then put into the airflow dryer for drying, so that the water content is 7%, and then made into 90 mesh fineness particles to form plant fiber inorganic light Quality filling aggregate, put into inner membrane waterproof bag for subsequent use, the stirring time of each step is identical with embodiment 1.

Embodiment 3

[0029] In the mixing tank of the cement mortar mixer, add 4 / 5 tank capacity of magnesium chloride solution with a concentration of 20% and a temperature of 29 degrees Celsius, add 2 / 3 tank capacity of plant fiber and stir for 5 minutes to degrease, then add the weight accounted for the amount of plant fiber. 50% fly ash with a mesh number of 350 was stirred for 5 minutes to fill the holes, then added a 1:20 aqueous solution of sodium methyl silicate that accounted for 35% of the amount of the fly ash and stirred for 5 minutes to gel; After the gelling treatment, the plant fibers are drenched to make the water content 35%, and then put into the airflow dryer for drying, so that the water content is 8%, and then made into particles with a fineness of 100 meshes to form the plant fiber inorganic The lightweight filling aggregate is put into an inner film waterproof bag for subsequent use, and the stirring time of each step is the same as that of Example 1.

Abstract

The invention relates to a vegetable fiber inorganic lightweight filling aggregates, which is prepared by the following steps: adding vegetable fiber in a magnesium chloride solution with concentration of 20% and temperature of 25-30 DEG C and then stirring to remove fat, adding fly ash with 300-400 meshes and stirring for filling perforation, adding a methyl-sodium silicate aqueous solution for stirring gel with ratio of 1: 20; removing gel and processing, drying the vegetable fiber, wherein water content is 5-8%, then granulating to form the vegetable fiber inorganic lightweight filling aggregates. According to the invention, fat removal, perforation filling and gel inorganic modification treatment are carried out on vegetable fiber, defects of easy decomposition, easy damage by worms and high water absorption can be basically overcome for using a straw raw material as a permanent building element, the vegetable fiber inorganic lightweight filling aggregates provides technology and product for smooth development, and promote the ecologicalization and weight reduction level of buildings.

Description

technical field [0001] The invention relates to a building material, in particular to a modified plant fiber inorganic lightweight filler aggregate. Background technique [0002] Ecological construction and lightweight construction are issues that need to be solved urgently in the development of the construction industry at this stage. It is the only way to change the current construction industry, which suffers from high energy consumption, high emission, heavy self-weight, and cumbersome construction techniques. The realization of building ecology and light weight will improve the environmental protection, green level, low-carbon, and recyclable properties of buildings, and promote the development of building dry method integrated building construction methods for building earthquake resistance, energy saving, land subsidence, and land restoration. Transformation has very important and critical significance. [0003] To achieve ecological and lightweight construction, we ...
