摘要： Disclosed by the present invention are an aqueous polyurethane functional mask substrate and an application thereof. Two kinds of water-based polyurethane dispersions are used as the main components of the mask substrate. The transdermal penetration and absorption of functional ingredients such as whitening, moisturizing and anti-aging ingredients in facial mask products are promoted by means of the special cross-linked structures of polyurethane films. During use, a mask is evenly applied to the face; and after the mask dries, the entire mask may be removed directly or removed after being moistened using water. The mask substrate according to the present invention is also applicable to body masks such as a hand mask, a neck mask and a back mask.

摘要： The present invention belongs to the technical field of aqueous epoxy coatings, and especially relates to an ionic aqueous epoxy curing agent, a preparation method therefor and the use thereof. The aqueous epoxy curing agent is prepared by reacting the following raw materials in parts by weight: a) 1 part of a polyepoxy compound, b) 1.3-6 parts of a multifunctional compound, c) 0.2 to 1.25 parts of a monoepoxy compound, and d) 0.01 to 0.23 parts of a sultone, wherein the multifunctional compound has four or more active hydrogens. The curing agent obtained in the present invention not only has a good hydrophilic effect and very good thinning performance, the paint film prepared by mixing same with an epoxy dispersion has the following advantages: excellent salt spray resistance and water resistance, strong adhesion, high hardness, etc.; in addition, the preparation process of the curing agent is simple, the conditions are mild, and room temperature curing is carried out.

摘要： A preparation method for an emulsifier, an emulsifier, an aqueous epoxy resin dispersion, and a formulation method. The preparation method for an emulsifier comprises reacting aminosulfonic acid and/or a sulfamate as a first reaction raw material with an epoxy resin in the presence of water, so as to obtain an ionic active emulsifier. The ionic active emulsifier molecule comprises at least one epoxy group from an epoxy resin and at least one sulfonic acid or sulfonate group from the first reaction raw material. The aqueous epoxy resin dispersion prepared by using the emulsifier has the characteristics of good stability and good corrosion resistance after curing, and can be used in the fields of coatings, adhesives, etc.

摘要： A self-crosslinkable polyurethane or polyurethane-urea aqueous dispersion, a preparation method therefor, and a use thereof. Side chains of the polyurethane or polyurethane-urea contain non-sterically-hindered siloxy groups. During the drying and activation of the aqueous dispersion, the siloxys in the side chains are hydrolyzed and crosslinked with each other to increase the cross-linking density, significantly improving the heat resistance, the humidity resistance, and other properties of an adhesive obtained therefrom. The aqueous dispersion itself has a good stability. In addition, an application system based thereon has an excellent stability and a long storage time. The aqueous dispersion is suitable for the preparation of high quality paints and sealants, especially adhesives.
