Problems solved by technology

[0004] However, there are still problems in the production of ceramic additives in my country, such as complex preparation process, long reaction time, high energy consumption, and serious pollution. Moreover, the functions of the ceramic additives produced are relatively single, and they often need to be combined with other ceramic additives in the application process. Coordinated use increases production costs

Abstract

The invention discloses a preparation method of ceramic additive by modified composite biomass base and an application thereof. The method includes steps of mixing concentrated landfill leachate with starch under ultrasound wave catalyst, and then preparing black loose powder shaped ceramic additive through alkalization, sulfonation and quaterisation, and performing spraying and drying; after mixing, performing alkalization and sulfonation reactions on landfill leachate concentrated solution and starch; thus the activity of effective molecular structure can be improved; the further quaterisation can effectively control the product molecular weight, thus the prepared ceramic additive has good dispersing performance while can largely improve the ceramic blank generating intensity; moreover, the prepared ceramic additive has multiple functions such as dispersing, water reduction, wear assisting, sticking and defoaming; thus the side product of the waste treatment is recycled and effectively used, the crisis of non-renewable energy resource is released, the actual application value and the social value of the side product during the waste disposal process are realized.

Description

technical field [0001] The invention relates to the fields of fine chemical industry and environment-friendly materials, in particular to a method for preparing a ceramic additive by modification of a composite biomass base and its application. Background technique [0002] As a big country in ceramic production, my country's ceramic output has ranked first in the world for several consecutive years, among which the output of daily-use ceramics accounts for about 70% of the global output, the output of decorative art ceramics accounts for 65% of the global output, and the output of architectural ceramics also accounts for the global total. About 50% of the output. However, since my country is a country that is relatively poor in energy and resources, and the ceramic industry is an industry that is highly dependent on energy and resources, it needs to consume more than 100 million tons of high-quality mineral raw materials every year, and the energy consumption equivalent to s...
