Problems solved by technology

[0006] Plant fiber is an extremely flammable material. In order to achieve a good flame retardant effect, it is inevitable to use a large amount of flame retardants. The organic flame retardants used in the above inventions and existing patents have high toxicity of decomposition products, Disadvantages such as large smog are not suitable for plant fiber wall decoration materials, and the retention rate of inorganic flame retardants is low, resulting in unfavorable consequences such as increased white water concentration, difficult quantitative control, and heavy wastewater treatment load.

Embodiment 1

[0031] A method for preparing a flame-retardant plant-based wall decoration material, the main scheme of which is as follows:

[0032] Step 1: According to the number of parts by mass, add 100 parts of plant fibers to hydrochloric acid with a mass percentage concentration of 10%, 4 parts of zinc chloride, control the temperature at 60°C, and process for 30 minutes. After the treatment, the plant fibers are dehydrated by spiral extrusion; After completion, add water for beating, the concentration of plant fiber is 5.2%, beating and dispersing for 20 minutes, stirring for 2 hours, and filtering to obtain chlorinated raw plant fiber;

[0033] Step 2: Then mix well with 6 parts of 3-trimethylsilylpropenol and 100 parts of water, control the temperature at 60°C, and stir for 3 hours to obtain unsaturated silicon-based plant fibers;

[0034] Step 3: Then add 10 parts of magnesium hydroxide, 9.4 parts of diallyl dimethyl ammonium chloride, 0.1 part of potassium persulfate, stir evenl...

Embodiment 2

[0042] A method for preparing a flame-retardant plant-based wall decoration material, the main scheme of which is as follows:

[0043] Step 1: According to the number of parts by mass, 120 parts of plant fibers are added to hydrochloric acid with a mass percentage concentration of 12%, 5 parts of zinc chloride, the temperature is controlled at 65°C, and the treatment is carried out for 60 minutes. After the treatment, the plant fibers are dehydrated by spiral extrusion; After completion, add water for beating, the plant fiber concentration is 6.8%, beating and dispersing for 25 minutes, stirring for 4 hours, and filtering to obtain the chlorinated raw material plant fiber;

Abstract

The invention relates to the field of preparation of building materials, and in particular, relates to a preparation method of a flame-retardant plant-based wall decorative material. The degradable wall decorative material is prepared from a plant fiber raw material, so that the problems of resource waste and environmental pollution caused by combustion can be solved, and the intrinsic value of the product can be improved; for solving the flame-retardant problem of the material, a modified starch surface coated inorganic flame retardant is added in the preparation process, and the flame retardant is prepared by coating magnesium hydroxide and aluminum hydroxide on cationic modified starch after gelatinization, and has the advantages of no toxicity of decomposition products, small smoke andthe like; the coating of the cationic modified starch increases the adhesiveness between inorganic particles and plant fibers, is beneficial to improving the retention rate, and solves the problems of low retention rate of an inorganic flame retardant, increase of the concentration of white water, difficulty in quantification control, heavy wastewater treatment load and the like caused by the lowretention rate of the inorganic flame retardant.

Description

technical field [0001] The invention relates to the field of building material preparation, in particular to a preparation method of a flame-retardant plant-based wall decoration material. Background technique [0002] my country is rich in non-timber plant fiber resources, but most of them have not been utilized economically and effectively. Most non-wood plant fiber raw materials are directly burned, which not only wastes resources, but also seriously endangers the natural ecological environment. The use of non-wood plant fiber raw materials to prepare plant fiber molding wall decoration materials can well solve the problem of utilization of non-wood plant fiber resources, improve its utilization value, and at the same time meet the needs of the country in building an energy-saving society and benefit the economy. recyclable development. [0003] CN101476250A discloses a method for producing slurry for fiber molding environment-friendly wall decoration materials. The me...
