Glue with high negative oxygen ion and low formaldehyde release quantity for impregnated paper and preparation method thereof

Abstract

The invention provides glue with high negative oxygen ion and low formaldehyde release quantity for impregnated paper and a preparation method thereof. The glue is prepared from the ingredients: 100 weight parts of low-formaldehyde-emission glue, 0.2 to 0.3 weight part of anti-sticking agents, 0.3 to 0.4 weight part of release agents, 0.08 to 0.1 weight part of dustproof agents, 0.1 to 0.15 weightpart of curing agents, 8 to 19 weight parts of negative ion powder, neutral dispersants for regulating 0.5 to 0.8 weight part of dispersing agents to the neutral state by a sodium hydroxide solution,wherein the concentration of the sodium hydroxide solution is 0.625 to 0.65mol / L. When the glue is applied to impregnated glue film paper, a large number of negative ions can be generated; the formaldehyde release quantity of the glue is very low, so that the quality of air in environment is effectively improved; meanwhile, the addition of negative oxygen powder does not influence the toughness and the later-period pressing and attaching performance of the impregnated paper; the attractive appearance and the use of the product are also not influenced.

Description

technical field [0001] The invention belongs to glue for impregnating paper, in particular to a glue for impregnating paper with high negative oxygen ion and low formaldehyde emission and a preparation method thereof. technical background [0002] With the shortage of wood, various impregnated paper veneers to replace logs are widely used in the decoration of homes and public places because of their reasonable price and rich patterns, and they are everywhere in people's lives. The ensuing pollution of decorative materials is increasing, especially the generation of formaldehyde release, which has caused many new houses after decoration to be unable to move in immediately and the damage to the human body caused by the long-term release of formaldehyde still exists after moving in. A large number of volatile gases in the decoration materials have positive charges and absorb a large amount of negative ions in the air. If you stay in a newly decorated place for a long time, you ...

Problems solved by technology

The first of the four methods requires frequent replacement of the filter element, which is costly; the second is the outer layer of the board and the wallpaper, which affects the release of negative ions. In order to increase the release of negative ions, the increase in the amount of negative ion powder is added, resulting in cost increases and The difficulty of the processing technology increases, which is not conducive to large-scale promotion; the addition of formaldehyde scavenger cannot reduce the amount of formaldehyde release, but only slows down the release rate of formaldehyde. Formaldehyde has been releasing and consuming negative oxygen ions; adding a large amount of rare earth and The impregnated film paper produced by tourmaline powder is particularly brittle, and it is difficult to press and stick to the plate. After pressing, the tape and the plate will be separated.
