Color-controllable zeolite modification method

Abstract

The invention discloses a color-controllable zeolite modification method, and relates to the field of environment-friendly decorative materials. The method comprises four working procedures of raw material pretreatment, calcination, cooling and finished product treatment, and specifically comprises the following steps: Step 1: carrying out crushing-screening granulation treatment on a zeolite raw material, and specifically, respectively treating the zeolite raw material into powdery, granular and larger blocky materials; 2, washing the zeolite raw materials with different particle sizes according to requirements, carrying out photocatalyst loading treatment, and further carrying out inorganic colorant loading treatment and wet treatment; 3, based on the steps, drying after the treatment is completed; and 4, carrying out calcination treatment on the pretreated raw materials in the above step. According to the invention, natural zeolite is adopted as a raw material, and the requirements of color controllability are met on the premise of improving the adsorption capacity of zeolite and the function of degrading formaldehyde and other volatile organic pollutants by a loaded photocatalyst by controlling the pretreatment mode, the calcination temperature, the calcination time, the cooling schedule and the like of the raw material.

Description

technical field

[0001] The invention relates to the field of environment-friendly decorative materials, in particular to a color-controllable zeolite modification method. Background technique

[0002] Decorative materials such as coatings and panels in modern home decoration contain toxic substances such as formaldehyde, benzene, volatile organic compounds, and ammonia, which seriously threaten people's health. To solve this problem, we should start from the quantity aspect. On the one hand, we should choose environmentally friendly materials to reduce pollutants. On the other hand, it strengthens the removal of pollutants. Zeolite has ion exchange, adsorption separation, catalysis, stability, chemical reactivity, reversible dehydration, electrical conductivity, etc., and has a wide range of applications in chemical, pharmaceutical, environmental protection, building materials and other fields. Application, due to its adsorption and photocatalyst-loading properties, after pr...
