Description

Water-based mask liquid for kitchen

Technical Field

The invention relates to the field of household chemical products, in particular to an aqueous mask liquid for kitchens.

Background

Kitchen cleaning has long been a major challenge in home cleaning. Especially wall tiles, on which oily smoke stains can be condensed into yellow spots after cooking in a kitchen for a period of time. However, many people are careless for cleaning due to work and family affairs, stubborn stains are formed for a long time, and even if the people use kitchen cleaning products for cleaning, the people also take time and labor, and the people can not clean the kitchen cleaning products. Unclean kitchen environment can cause kitchen pollution, easily cause food pollution, cause diseases and harm human health.

In order to reduce scrubbing, people usually stick preservative films on the surfaces of the tiles for isolating oil stains, but the preservative films are difficult to stick flatly and are not attractive. The preservative film also has the problem of flammability and potential safety hazard. Kitchen stickers are also sold in the market, but the size of the kitchen sticker is fixed and does not necessarily meet the actual condition of each family, and the kitchen sticker needs to be cut or cannot be pasted in a part of places when being used. Meanwhile, when the sticker is torn off, glue is remained on the surface of the ceramic tile and still needs to be manually removed.

In order to solve the problems, the invention provides a novel water-based facial mask liquid for kitchens, which can be uniformly spread on the surfaces of tiles in kitchens by means of brushing, spraying or the like. Meanwhile, a film formed by the aqueous mask liquid after curing has certain adhesive force and cannot fall off. Moreover, the formed ultrathin membrane does not affect the appearance, and can be easily torn off in a whole piece like a mask. Therefore, the kitchen cleaning device can ensure the cleanness and sanitation of the kitchen, greatly reduce the labor intensity and enable the kitchen to be easily cleaned.

Adding BYK-348, BYK-018 and BYK-425 in sequence under stirring, and stirring at normal temperature for 10min to obtain kitchen mask liquid for later use.

TABLE 5

The results show that if the amount of film-forming resin is too low (e.g., less than 40 wt%), it will result in failure to form a film and severe sagging.

TABLE 6

The results show that aqueous polyurethanes with relatively low molecular weights (e.g., less than 30000 daltons) can form films, but the resulting films have poor toughness and are prone to breaking, which is not suitable for kitchen tile applications.

Comparative example 5: addition amount of thickener

The preparation method comprises the following steps: 60 percent of waterborne polyurethane is accurately weighed in a beaker, a certain amount of deionized water (see table 7) is added, and the mixture is uniformly stirred. Adding BYK-348 in an amount of 0.4%, BYK-018 in an amount of BYK-425 (see table 7) while stirring, and stirring at normal temperature for 10min to obtain the kitchen mask liquid for later use.
