Healthy environment-friendly white emulsion and preparation method thereof

Abstract

The invention discloses a healthy environment-friendly white emulsion which comprises the following raw materials in parts by weight: 8-10 parts of tourmaline powder, 2-4 parts of dibutyl phthalate, 30-40 parts of deionized water, 3-5 parts of propylene glycol, 1-3 parts of zeolite powder, 0.2-0.4 part of baking soda, 14-20 parts of polyvinyl alcohol, 7-9 parts of modifier, 2-4 parts of turpentine, 0.6-1.2 parts of dibutyl butyl diacid sodium sulfonate, 1-2 parts of acetobutyryl cellulose, 0.7-0.9 part of initiator, 1-3 parts of emulgator, 100-120 parts of adhesive and 5-9 parts of enhancing starch. The healthy environment-friendly white emulsion disclosed by the invention has excellent bonding strength and curing time index; the material contains no formaldehyde or benzene series, is nontoxic and harmless, is environmentally friendly and safe and is capable of releasing anions beneficial to health; and meanwhile, the preparation method according to the invention is characterized by easily acquired raw materials, low cost, simple process and higher practical value and application prospect.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly materials, in particular to a healthy and environmentally friendly high-quality white latex and a preparation method thereof. Background technique [0002] White latex, namely vinyl acetate emulsion, is a kind of thermoplastic adhesive prepared by emulsion polymerization of vinyl acetate. In 1937, W. Starck and Frendeberg of Farben invented the method of using polyvinyl alcohol as a protective glue for vinyl acetate emulsion polymerization, which greatly promoted the development of polyvinyl acetate emulsion industry. In the field of furniture and woodworking manufacturing, the pattern of adhesives with white latex as the main body has basically remained unchanged. White latex is also an auxiliary material used in a large amount in the decoration industry. White latex is favored and valued by people because of its good bonding performance, safety and environmental protection, and...

Problems solved by technology

In the same way, when the moisture content of the wood is high, the bonding strength will decrease, and the parts will take a long time to form, etc.

This defect is difficult to meet the requirements of practical application, and also limits the application of white latex to a large extent.

[0004] On the other hand, with the improvement of people's material life, home decoration is becoming more and more common, which leads to the extensive use of man-made panels in the decoration process, especially the increasing shortage of natural wood, which leads to an increase in the use of man-made panels.

It is well known that a large amount of urea-formaldehyde glue is used in the production process of man-made boards, resulting in serious release of free formaldehyde, which pollutes the human body and the surrounding environment seriously, and seriously affects people's health. Long-term exposure to formaldehyde may lead to leukemia.
