Problems solved by technology

However, when printing on textiles, the color of the printing paste is usually required to be light-colored, otherwise it will affect the aesthetics of the printing color
On this premise, conventional tourmaline powder is added to the printing paste in the prior art. Due to its low whiteness, the amount of tourmaline powder added cannot exceed 5% of the total mass of the textile, or even lower It only accounts for 1%, which makes the printed textiles unable to achieve the functional characteristics of the introduction of tourmaline. On the contrary, if the added amount is exceeded, the color of the printing paste will become darker and cannot be used. Therefore, this is the current application of tourmaline powder. Due to the technical problems of printing paste; in addition, due to the problems existing in the current surface modification process of tourmaline powder, its surface is smooth and easy to desorb, which makes tourmaline powder prone to powder falling when it is applied to printed fabrics, and the modified electrical After the stone powder desorbs and turns black, it will also cause serious problems of discoloration of the printing paste

Abstract

The invention relates to the technical field of tourmaline functional materials, in particular to a preparation method of tourmaline-molecular sieve printing paste, which comprises the following steps: step 1, preparing tourmaline powder-molecular sieve powder, step 2, preparing pre-dispersed tourmaline-molecular sieve surface modification paste, and step 3, preparing the tourmaline-molecular sieve printing paste. A layer of sodalite can be creatively grown on the surface of tourmaline, the sodalite is very firm and not prone to falling off, the whiteness of the sodalite is remarkably improved to 55-65, the technical problem that application of existing tourmaline powder in textiles is limited is solved, the adding amount of the sodalite can be improved to 5-15%, the attractiveness of the printing color of the textiles is guaranteed, and the application range of the sodalite is widened. And multiple synergistic effects of pyroelectricity, far infrared radiation, adsorption deodorization and the like of the tourmaline and molecular sieve composite functional material can realize real application value in textiles.

Description

technical field [0001] The invention relates to the technical field of tourmaline functional materials, in particular to a preparation method of tourmaline@molecular sieve printing paste. Background technique [0002] Tourmaline is a silicate mineral with iron, aluminum, sodium, and lithium ring structure characterized by boron. performance. Tourmaline combines the properties of various mineral functional materials due to its special structure. It can be combined with other materials by physical or chemical methods to produce various functional composite materials, which are used in electronics, medicine, chemicals, building materials and other fields. . For example, the master's thesis "Study on Thermal Alteration Products and Properties of Tourmaline under Alkaline Conditions" directed by the inventor, namely, using the natural mineral tourmaline as raw material, discusses the synthesis of sodalite from tourmaline in an alkaline hydrothermal environment. , Cannonite, an...
