Description
WATER-BASED INTERIOR PAINT AND PREPARATION METHOD THEREOF TECHNICAL FIELD
The present invention relates to the technical field of interior decorative coatings, and in particular, to water-based interior paint and a preparation method thereof.
BACKGROUND
With the rapid development of the society and the rising of people's living standards, people raise increasingly high requirements for interior decorations of buildings. Coatings play an increasingly important role in building decorations. In recent years, there is an increasing demand for building decorative coatings.
Latex-based interior paint is a type of water-based coating prepared by mixing synthetic resin emulsion as a binder with a pigment, fillers, and various auxiliaries. It is also referred to as waterbased interior paint and is one of the main decorative materials for indoor walls and ceilings. Due to a good decorative effect and convenient application, the latex-based paint is widely used in interior decoration.
Currently, water-based interior paint on the market usually contains volatile organic compounds (VOCs) and formaldehyde exceeding a standard limit. VOCs are toxic and harmful gases. Therefore, when released in the air, VOCs will result in serious environmental pollution. In addition, VOCs will cause serious harm to the nervous system and hematopoietic function of a human body if the human body is in contact with or inhales VOCs for a long time, even trigger cancerization and other serious diseases and even death. VOCs are also one of the important reasons for an increase in an ozone concentration in the air and the formation of regional photochemical smog, acid rain, and haze combined pollution. A main hazard of formaldehyde manifests as the irritation to skin and mucous membrane. When a concentration of indoor formaldehyde reaches a specific value, people will feel uncomfortable. When the formaldehyde concentration is greater than 0.08 mg/m3, the formaldehyde can cause red eyes, itching eyes, throat discomfort or pain, vocal hoarseness, sneezing, chest congestion, asthma, dermatitis, etc.
SUMMARY
In view of this, the present invention provides water-based interior paint and a preparation method thereof. The water-based interior paint provided in the present invention contains ultra-low content of VOCs, releases no free formaldehyde, and has better comprehensive performance than that of a superior product stipulated in GB/T9756-2018 Synthetic Resin Emulsion Coatings for

Dry plate experiment: Viscosity of the prepared water-based interior paint was adjusted by using deionized water until the water-based paint could be roll coated and brushed; primer sealer and primer were first coated to an integrated plate, and dried for 12 h; the VOC-free water-based interior paint was roll coated or brushed on the integrated plate, where a coating thickness was controlled between 60-80 pm. After coating, the appearance, surface drying time, hard dry time, low temperature film-forming property, and glossiness of the water-based paint could be detected. After the water-based paint was dried for seven days in a natural environmental condition, the comprehensive performance (water resistance, alkali resistance, and scrub resistance) thereof was detected.

Note: ND in Table 3 means undetected.
It can be learned according to the results in Table 3 that, when the amount of the water-based special emulsion is increased, the glossiness of the prepared water-based interior paint is improved, a surface drying speed is reduced, and the isothiazolinone content is increased; when the amount of the film-forming additive is increased, the phthalate content and the VOC content of the prepared water-based interior paint are increased; in Embodiment 1, the content of the film-forming additive is 3% and exceeds the range of the present invention, and the VOC content of the prepared waterbased interior paint is 12 g/L and exceeds a requirement in GB/T 23986; and when the amount of
2020100559 14 Apr 2020 the calcined kaolin and other fillers is increased, the amount of heavy metals is increased, It can be learned from Table 3, the comprehensive performance of the products in Embodiments 4 and 5 is the best. The products have scrub resistance exceeding 7000 times, have no VOCs and no free formaldehyde, and contain very low content of phthalic acid. In addition, both the isothiazolinone content and the total content of the isothiazolinones of the products are very low and far below the standard requirements. The comprehensive performance of the products obtained in Embodiments 1-5 is better than that of a superior product stipulated in GB/T9756-2018 Synthetic Resin Emulsion Coatings for Interior Wall. The water-based interior paint provided in the present invention contains no VOCs, free formaldehyde, and heavy metal. When the water-based paint is applied to house decoration, the house can be immediately used after decorated. Therefore, the water-based paint is very suitable for baby rooms, children's rooms, shopping malls, entertainment venues, airports, stadiums, railway stations, and other densely populated places. These facilities can be immediately used after on-site construction using the water-based paint, without causing any impact on the human body.
The foregoing descriptions are only preferred implementations of the present invention. It should be noted that, for a person of ordinary skill in the art, several improvements and modifications may further be made without departing from the principle of the present invention. These improvements and modifications should also be deemed as falling within the protection scope of the present invention.
