Problems solved by technology

The outstanding advantage of the low-alkali method is that the low-alkali molar ratio is used, the consumption of sodium hydroxide is only one tenth of that of the high-alkali method, the side reactions are less, and the by-product sodium acetate is correspondingly less. The disadvantage is that the alcoholysis speed is slow, Sodium acetate in polyvinyl alcohol products is not easy to wash off due to its dense structure

Embodiment Construction

[0088] The invention discloses a preparation method of a green and environment-friendly adhesive that does not contain harmful solvents to the human body, relates to the field of chemistry, and in particular relates to adhesives used in various wood products. This method is a method for efficiently preparing green and environmentally friendly adhesives from polymer monomers. It is polymerized with KH-570, NXT-201, etc. in the presence of preservatives and emulsifiers with negative ion aqueous solutions, and then blended and mixed at 85 A preparation method characterized by aging B emulsion at -90 degrees for 50 minutes. This method has the characteristics of simple process, short reaction time; stable quality, no yellowing; no toxic solvents such as benzene and free formaldehyde; cheap price, etc., and its quality can reach the level of the best domestic products.

[0089] Its production process:

[0090] (1) Put the negative ion water into the dispersing kettle, add F2 and F...

Abstract

The invention relates to an environment-friendly adhesive and a preparation method and belongs to the technical field of fine chemical industry. The invention provides a novel recipe and the preparation method for preparing the environment-friendly adhesive. The technical key of the invention is to polymerize different polymerization monomers, coupling agents, evocating agents, emulsifying agents and negative ion dispersing mediums into crosslinkable and curing high molecular polymer in a certain temperature by a certain method. The environment-friendly adhesive is suitable for woodworks, such as industries of hard board, furniture and composite floor board. The physical mechanical performance and the environmental protection index of the various woodworks produced by using the novel environment-friendly adhesive meet and even surpass the national standard requirement of various woodworks. The invention can effectively remove the pollution and danger of benzene and formaldehyde.

Description

technical field [0001] The technical field belongs to fine chemical industry. The application of this green environmental protection adhesive is suitable for wood products, such as: wood-based panel industry, furniture industry and composite floor industry. The physical and mechanical properties and environmental protection indicators of all kinds of wood products produced by using this new type of green environmental protection adhesive reach and exceed GB / T Standard requirements for various wood products. Background technique [0002] (Text content) The technical background of the main components and key components of the green environmental protection adhesive of the present invention: [0003] 1. Vinyl acetate content in the range of 70% to 95% is usually in the state of emulsion, called VAE emulsion. The appearance of VAE emulsion is milky white or slightly yellow. The research on ethylene-vinyl acetate copolymers abroad is relatively early. In 1938, British Imperi...
