Adhesive, plane material with adhesive layer and preparation method

Abstract

The invention relates to an adhesive which comprises a first composition, a second composition and a third composition. The first composition comprises the following raw material components in parts by weight: 10-20 parts of epoxy resin, 10-20 parts of methacrylic acid, 50-60 parts of butyl acrylate, 3-7 parts of hydroxypropyl acrylate and 8-12 parts of vinyl acetate; the second composition comprises the following raw material components in parts by weight: 15-25 parts of the first composition, 40-60 parts of natural rubber and 20-40 parts of petroleum resin; and the third composition is prepared from the following raw material components in parts by weight: 70-90 parts of butyl acrylate, 5-15 parts of hydroxypropyl acrylate and 5-15 parts of vinyl acetate. The adhesive is applied to plane materials such as drawings, wallpaper and the like, deformation, wrinkling and chap of the attached plane materials due to the fact that stress of the plane materials, a bonding layer and a base layer cannot be released after attachment are prevented, the surface of a base material is clean and free of adhesive after the plane material is removed, and the surface of the base material cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to an adhesive, a surface material with an adhesive layer and a preparation method. The adhesive is mainly used in fields such as furniture and home decoration. Background technique [0002] With the improvement of the economic level, people's requirements for the living environment are getting higher and higher, which promotes the rapid development of the furniture and home decoration industry. Among furniture and home improvement materials, graphic decorations and wallpapers are widely used interior decoration materials, because graphic decorations and wallpapers have many advantages such as diverse colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and affordable prices. It is unmatched by other interior decoration materials. [0003] Taking wallpaper as an example, wallpaper is usually composed of a surface material and an ad...

Problems solved by technology

[0004] When positioning and attaching during construction, due to the strong adhesion performance of the brushed adhesive layer, in the case of misalignment, it is necessary to remove and re-attach, resulting in damage to the adhesive layer or deformation of the surface material, making it impossible to perform secondary repairs Positioning and fitting; when attaching to a rough surface, due to the uneven effective contact surface and gaps in the attachment interface, the attachment is not firm, bulging, and wrinkling; after attachment, the stress of the wallpaper, coating, and base layer cannot Release leads to deformation, wrinkling, and chapping of the surface material after lamination; after lamination, the surface material will bulge, wrinkle or even warp due to aging and loss of adhesion of the lamination adhesive layer; part of the adhesive layer will produce irritating odor after aging and decomposition. Mildew and other environmental pollution problems; when replacing new wallpaper, it is difficult to remove the old wallpaper and the surface is difficult to clean or damage the surface after removal, etc.
