Abstract

The invention belongs to the field of home decoration, and in particular relates to a modified melamine-formaldehyde resin impregnating solution and a preparation method and application thereof. The melamine formaldehyde resin impregnating solution is composed according to the mass parts: 320-380 parts of melamine, 400-450 parts of formaldehyde, 12-18 parts of ethyl carbamate, 8-15 parts of propylene glycol, 8-15 parts of ethanol, and an appropriate amount of sodium hydroxide , 180-220 parts of water, 50-80 parts of modifier. The impregnated liquid prepared by the present invention can impregnate the decorative wood grain paper, and the obtained impregnated paper can make the surface color of PVC, aluminum alloy and stainless steel more colorful, which not only has the strength of the material itself, but also has the surface texture effect of wood grain; the impregnated liquid can also The medium paper can be impregnated, and the obtained impregnated paper can be hot-pressed into composite materials such as plastics and fiberboards, plastics and aluminum alloys, which can adapt to the requirements of different occasions and scopes.

Description

technical field [0001] The invention belongs to the field of home decoration, and in particular relates to a modified melamine-formaldehyde resin impregnating solution and a preparation method and application thereof. Background technique [0002] Decoration materials are classified according to the materials and materials. Interior decoration materials can be divided into coatings, solid wood, compressed boards, composite materials, sandwich structural materials, foam, etc.; outdoor decoration materials mainly include cement mortar, terrazzo, colored bricks, ceramic tiles, paints, glass Curtain wall, aluminum alloy, etc. [0003] Melamine formaldehyde resin has high heat resistance and moisture resistance, as well as bright and transparent realism under the light, odorless, tasteless and colorless, so it has many advantages in the application of decorative wood-based panels. However, melamine formaldehyde resin still has a short storage period. The impregnated paper is bri...
