Abstract

The invention belongs to environment-friendly type starch adhesives and in particular relates to an environment-friendly type starch adhesive for decoration and a preparation method thereof. The environment-friendly type starch adhesive is prepared from 1 to 6 percent of a protection adhesive body, 5 to 18 percent of a polymerization system, 5 to 10 percent of starch, 2 to 5 percent of inorganic filler, 0.1 to 0.5 percent of an initiator, 0.2 to 1.5 percent of a plasticizer, 0.1 to 0.3 percent of fungicide, 60 to 85 percent of de-ionized water, 1 to 5 percent of an emulsifying agent, 0.1 to 0.5 percent of a metal ion chelating agent, 0.5 to 3 percent of a pH (Potential of Hydrogen) value regulator and 0.1 to 0.5 percent of a de-foaming agent; the environment-friendly type starch adhesive can be prepared through steps of dispersing, dissolving, polymerizing, plasticizing, enhancing, guaranteeing quality and the like. The starch adhesive provided by the invention has the advantages of environment protection, good storage stability and high attachment force and especially has low cost, high bonding strength and good diluting and film forming performance and is easy to brush; the environment-friendly type starch adhesive is widely applied to various fields including wood processing, furniture assembling, inner wall surface decoration of buildings, fiber boards, corrugated board packaging boxes, daily use, mounting and the like.

Description

technical field [0001] The invention belongs to an environment-friendly water-based adhesive, in particular to an environment-friendly starch glue which can be used for decoration and a preparation method thereof. Background technique [0002] Starch adhesive is based on natural starch glue (such as corn starch, wheat starch, potato starch, rice starch, tapioca starch and sweet potato starch, etc.) The prepared natural environment-friendly adhesive substance. Starch glue has the advantages of non-toxic and tasteless, no pollution to the environment, rich sources of raw materials, and low price. It is widely used in wood processing, furniture assembly, packaging materials, architectural decoration, paper, foam, plastic, daily use and mounting. [0003] Starch is a renewable natural polymer compound with good adhesiveness and film-forming properties. However, starch must be modified when used as an adhesive. Traditional starch modification methods include gelatinization, oxid...
