Embodiment 1

[0034] Take 30 parts of acrylic acid monomer, 0.1 part of tropolone copper salt, 0.1 part of azobisisoheptanonitrile, 0.1 part of dispersant, and 3 parts of negative oxygen ion powder into a single-necked flask, and carry out the process at a speed of 600r / min. Stir until micelles are formed between the acrylic acid monomer and the negative oxygen ion powder. After the micelles were formed, they were heated to 65°C, and their viscosity was monitored in real time. After 45 minutes, the viscosity reached 1600mpa.s, and the flask was transferred to liquid nitrogen for rapid cooling to stop the reaction. After warming up to room temperature, add 1 part of defoamer, whose viscosity is 4300mpa.s.

[0035] Add 0.1 part of azobisisoheptanonitrile before use. Apply this environmentally friendly glue on the surface of wood (thickness 1.0mm), heat it to 100°C and cure for 1 hour, and the release of negative oxygen ions on the surface of the board can reach 1500-2500 per cubic centimeter...

Embodiment 2

[0037] Take 50 parts of methacrylic acid monomer, 0.2 part of tropolone copper salt, 0.1 part of azobisisoheptanonitrile, 2 parts of dispersant, and 10 parts of negative oxygen ion powder into a single-necked flask, and use 600r / min Stir at high speed until micelles form. After the micelles are formed, heat to 65°C and monitor their concentration in real time. After 30 minutes, the viscosity reaches 1500mpa.s. Transfer the flask to liquid nitrogen for rapid cooling to stop the reaction. After warming up to room temperature, add 1 part of defoamer, whose viscosity is 4800mpa.s. Add 0.5 parts of azobisisoheptanonitrile before use. Apply this environmentally friendly glue on the surface of wood (thickness 1.0mm), heat it to 100°C for 1 hour to cure, and the amount of negative oxygen ions released on the surface of the board after curing can reach 1800-3500 per cubic centimeter.

Embodiment 3

[0039] Take 30 parts of acrylic acid monomer, 20 parts of N-methylmaleimide, 1 part of tropolone copper salt, 0.1 part of azobisisoheptanonitrile, 10 parts of dispersant, and 10 parts of negative oxygen ion powder Put it into a one-necked flask and stir at a speed of 600r / min until micelles are formed between the acrylic acid monomer and the negative oxygen ion powder. After the micelles are formed, heat to 65°C and monitor their concentration in real time. After 35 minutes, the viscosity reaches 1500mpa.s. Transfer the flask to liquid nitrogen for rapid cooling to stop the reaction. After warming up to room temperature, add 1 part of defoamer, whose viscosity is 5300mpa.s. Add 1 part of azobisisoheptanonitrile before use. Apply this environmentally friendly glue on the surface of wood (thickness 1.0mm), and irradiate it with ultraviolet light for 30 seconds to cure the surface. After curing, the release of negative oxygen ions on the surface of the board can reach 1000-2300 ...

Abstract

The invention discloses an anion environment-friendly adhesive based on acrylic resin and a preparation method of the anion environment-friendly adhesive. The anion environment-friendly adhesive is prepared by pre-polymerizing the following components in parts by weight until the viscosity reaches 1000 to 30000mpa.s, then rapidly cooling and stopping polymerizing. The anion environment-friendly adhesive is prepared from the following components: 30 to 300 parts of acrylic monomer or methacrylic monomer, 0 to 300 parts of other free radical polymeric monomers without carboxylic acid groups, 1 to 60 parts of negative oxygen ion powder, 0.1 to 5 parts of an initiator for free radical polymerization, 0.1 to 5 parts of cycloheptatriene phenolic acetone copper salt and 0.1 to 10 parts of a dispersing agent. The negative oxygen ion powder is coated with carboxyl on the acrylic resin monomer to form a micelle with a core-shell structure; the micelle is heated to be pre-polymerized to form theenvironment-friendly adhesive with proper viscosity; the negative oxygen ion powder positioned on the core of the micelle endows the environment-friendly adhesive with a negative oxygen ion release function, so that the inhibition of formaldehyde release can be realized. The cycloheptatriene phenolic acetone copper salt is an efficient broad-spectrum antibacterial agent and can be used for inhibiting the growth of most harmful microorganisms in the living environment and realizing the functions of preventing mildew and resisting viruses.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an acrylic resin-based negative ion environment-friendly glue and a preparation method thereof. Background technique [0002] At present, a large number of adhesives are used in building construction, board treatment, furniture preparation, and home decoration, and these adhesives have more or less the problem of formaldehyde release. Formaldehyde, as a gas harmful to human beings, is known as the indoor "killer", which seriously endangers the health of newly renovated families, especially children, pregnant women and the elderly. In addition, the release process of formaldehyde in furniture and home decoration is relatively long, which can last for several years or even decades. Furniture and home decoration will become moldy with the change of environment during long-term use, and become the medium of virus and germ infection. If they cannot be treated and disinfecte...
