Abstract

The invention discloses a petal-containing paper-based decorative material and a preparation method thereof. The decorative material comprises a surface layer, a core layer and a bottom layer, wherein the surface layer and the bottom layer comprise softwood fiber pulp, water-soluble PVA (Polyvinyl Acetate) fiber pulp and double-component fiber pulp; and the core layer comprises softwood fiber pulp, hardwood fiber pulp and petal dispersant. According to the petal-containing paper-based decorative material, the surface layer and the bottom layer are rich in water-soluble polyvinyl alcohol fibers with high strength, water solubility and hot-melting adhesive effect, so that mechanical strength and interlayer adhesive force are provided for the material. The core layer supports the surface layer, and petals are natural, vivid, decorative and beautiful. Each layer adopts the same wet making method, the interlayer spray chemical aid is added for strengthening bonding, and the composite molded and hot-pressed interface is good in an adhesive status and is not layered.

Description

technical field [0001] The invention belongs to the technical field of special fiber manufacture, and in particular relates to a paper-based decoration material containing petals, and also relates to a preparation method of the decoration material. Background technique [0002] The paper-based decoration material containing petals is a kind of green packaging material made by combining synthetic fibers, petals and plant fibers. Petal decorations are popular for their beauty and pleasing to the eye. With the improvement of people's quality of life and the improvement of environmental protection awareness, the concept of "green and environmental protection" is constantly being strengthened when Chinese people buy goods. In the "green design" revolution, the pursuit of environmental protection awareness is always pursued, and the outer packaging design of products is required. beautiful. Therefore, today's environmentally friendly paper products should not only reflect safety...
