Problems solved by technology

[0005] However, the raw materials in the above-mentioned environmentally friendly adhesives use a large amount of solvents and aromatic diisocyanates. When encountering hot weather or strong ultraviolet radiation, the release of aromatic poisons will be accelerated, and heavy metals such as lead and mercury will remain, which have strong chronic toxicity to the human body. And it will also cause continuous pollution to the soil environment and groundwater; moreover, a large amount of silicon dioxide is added to the above-mentioned adhesive, and as the content of silicon dioxide increases, the adhesive is prone to cracking

[0044] 1. Preparation of epoxy-acrylic acid hybrid emulsion:

[0045] 1. Prepare raw materials: epoxy resin, acrylic acid monomer and alkyl acrylate monomer, vinyl alkyl phosphate, initiator, neutralizer, deionized water;

[0046] 2. Preparation process:

[0047] (1) Stir 80kg of water, 0.4kg of sodium dodecylsulfonate and 0.1kg of octylphenol polyoxyethylene ether evenly, heat up to 50°C, add 10.2kg of methyl methacrylate, 5.6kg of butyl acrylate and 1.2 kg methacrylic acid, continue to heat up to 75°C; add 0.15kg ammonium persulfate aqueous solution until the emulsion shows obvious blue light; add dropwise the mixed monomer of 10.2kg methyl methacrylate, 5.6kg butyl acrylate and 1.2kg methacrylic acid , dropwise added and incubated for 30 minutes to obtain a seed emulsion;

[0048] (2) While preparing the seed emulsion, dissolve 12kg E-51 epoxy resin with 52kg methyl methacrylate and 26kg butyl acrylate mixed monomer, then add 0.6kg benzoyl peroxide initiator, 0.3kg dodecy...

Embodiment 1

[0057] Add 380kg of water into the stirring container, add 5kg of acrylate copolymer dispersant, 15kg of hydroxyethyl cellulose, 20kg of antifreeze, 5kg of bactericide, and 3kg of defoamer at a stirring speed of 300rpm, fully disperse for 20min, and then stir Add 170kg of epoxy-acrylic hybrid emulsion, 300kg of elastic acrylic emulsion, 7kg of film-forming aids, 5kg of bactericides, 3kg of defoamers, 35kg of functional additives, 50kg of dustproof agents, and 2kg of thickeners at a speed of 500rpm. Further increase the stirring speed to 600rpm, stir for 5 minutes, filter and package as component A after passing the test; mix component A and component B evenly in a ratio of 100:6.2 to obtain a water-based environmentally friendly plastic runway adhesive.

Embodiment 2

[0059] Add 430kg of water into the stirring container, add 7kg of acrylate copolymer dispersant, 16kg of hydroxyethyl cellulose, 20kg of antifreeze, 6kg of bactericide, and 3kg of defoamer at a stirring speed of 300rpm, fully disperse for 20min, and then stir Add 130kg of epoxy-acrylic hybrid emulsion, 280kg of elastic acrylic emulsion, 6kg of film-forming aids, 6kg of bactericides, 4kg of defoamers, 35kg of functional additives, 55kg of dustproof agents, and 2kg of thickeners at a speed of 500rpm. Further increase the stirring speed to 600rpm, stir for 5 minutes, filter and package as component A after passing the test; mix component A and component B evenly in a ratio of 100:5.41 to obtain a water-based environmentally friendly plastic runway adhesive.

Abstract

The invention discloses a water-based environment-friendly plastic track adhesive and a preparation method thereof. The technical scheme is as follows: the water-based environment-friendly plastic track adhesive comprises a component A and a component B. The component A comprises the following substances in percentage by weight: 19-48% of deionized water, 0.3-0.8% of dispersing agent, 0.5-0.7% of defoaming agent, 0.2-0.5% of thickener, 1-2% of hydroxyethyl cellulose ether, 0.5-1% of film forming aid, 40-60% of water-based acrylate emulsion and 0.5-2% of bactericide. The component B comprises the following substance in percentage by weight: 5-10% of amine curing agent. The water-based environment-friendly plastic track adhesive substitutes the adhesive prepared from aromatic diisocyanates in the prior art. Even in hot days or under ultraviolet irradiation, the adhesive disclosed by the invention can not release aromatic toxic gases, thereby greatly enhancing the environment friendliness of the adhesive.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based environmentally friendly plastic runway adhesive and a preparation method thereof. Background technique [0002] The plastic runway is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, fillers, etc. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. It is an internationally recognized outdoor sports venue. Ping material. [0003] However, there have been many negative reports about plastic runways in the media recently. According to reports, the news that "toxic plastic track" appeared in many schools in a certain place caused students to experience symptoms such a...
