A kind of multifunctional ecological interior wall coating material and preparation method thereof

Abstract

The invention provides a multifunctional ecological inner wall coating material and a preparation method thereof, and belongs to the field of coating materials. The inner wall coating material is prepared by mixing the following raw materials: de-ionized water, an emulsion, a liquid aid, titanium dioxide, low-VOC (volatile organic compound) color paste, a functional composite material, white sand and a powder aid. The preparation method comprises the following steps: (1) adding the de-ionized water and the emulsion into a reaction kettle, adding the liquid aid and titanium dioxide in sequence while stirring, dispersing for 15 minutes, and performing color mixing by the low-VOC color paste according to the color sample design requirements of customers; (2) adding the functional composite material, the powder aid and the white sand into a powder mixer, mixing for 10 minutes, and discharging for later use; (3) slowly adding the discharged powder in the step (2) into the reaction kettle while stirring, uniformly mixing, checking, discharging and packaging. The coating material comprises functional materials such as a low-VOC emulsion, an environment-friendly aid, a lead-free pigment, a biological sterilization material, a humidifying material and a nanomaterial, and has the functions of decoration, protection, humidification, energy conservation, bacterial inhibition and killing, air purification, negative ion release and the like.

Description

technical field [0001] The invention relates to a coating material, in particular to a thick-coated multi-functional ecological interior wall coating material with a texture effect for the interior wall of a home and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of environmental protection and health has increased significantly, and the requirements for the living environment have become higher and higher. In addition to decorative properties, the coating materials for indoor walls have also put forward higher requirements for air humidity. At present, Air humidity is usually adjusted by using air conditioners and other humidity adjustment equipment, all of which are power-consuming equipment, while adjusting air humidity through wall materials can greatly reduce energy consumption, which is in line with the principle of energy saving and consumption reduction; at the same time, neg...

Problems solved by technology

[0004] At present, most of these products use a single biological sterilization or a single physical and chemical mechanism for antibacterial and antibacterial, and their long-term effectiveness is limited; secondly, although some of these products in the past also meet the current mandatory standards in terms of environmental protection indicators, However, it is difficult to reach zero in some indicators such as volatile organic compounds (VOC); thirdly, in the past, the decorative effect of such invented materials was mainly ordinary flat coating, and the thickness of the coating film was small, so that the content contained in the unit wall area The total amount of humidity-conditioning materials must be small, which greatly limits the performance of the humidity-conditioning function; fourth, in the past, such invented materials used powder fillers to consume a large amount of mineral resources such as quartz ore and limestone.
