Embodiment 1

[0025] To prepare 1000g of one-component polyurethane adhesive, first combine 500g of water-based polyurethane resin Bayhydrol-UH-A (aliphatic anionic polyurethane water-based dispersion with a solid content of 30%-70%) and water-based polyurethane resin Bayhydrol-UH-B( Add 500g of aliphatic anionic polyurethane aqueous dispersion with a solid content of 20%-40%) to the reactor, stir at room temperature for 10 minutes; then add substrate wetting agent (EW-514, Daorun Chemical Technology (Shanghai) Co., Ltd.) 1g, antifoaming agent (Foamex N, Tego) 1g, rheology additive (WT-105A, Hainame Steqian) 1g, stir at room temperature for 10 minutes to obtain the first component, when using it, Add 1% curing agent (XP-2547, Bayer) to the mixture and stir thoroughly to obtain the environmentally friendly water-based polyurethane adhesive for plastic sites.

Embodiment 2

[0027] To prepare 1000g of one-component polyurethane adhesive, first combine 400g of water-based polyurethane resin Bayhydrol-XP-A (aliphatic anionic polyurethane water-based dispersion with a solid content of 30%-70%) with water-based polyurethane resin Bayhydrol-XP-B ( Add 600g of aliphatic anionic polyurethane aqueous dispersion with a solid content of 20%-40%) to the reaction kettle, stir at room temperature for 10 minutes; then add a substrate wetting agent (750, Wuhan Yuancheng Co-Creation Technology Co., Ltd.) ) 1g, defoamer (Foamex 815N, Tego) 1g, rheology additive (881-A, Qinghong) 1g, stir at room temperature for 10 minutes to obtain component A, when using, add 9% to component A The curing agent (XP-2655, Bayer) is fully stirred to obtain the environmentally friendly water-based polyurethane adhesive for plastic sites.

Embodiment 3

[0029] To prepare 1000g of one-component polyurethane adhesive, first mix 600g of waterborne polyurethane resin Dispercoll-A (aqueous dispersion of aliphatic anionic polyurethane with a solid content of 30%-70%) and waterborne polyurethane resin Dispercoll-B (solid content of 20%). %-40% aliphatic anionic polyurethane aqueous dispersion) 400g was added to the reaction kettle, stirred at room temperature for 10min; then sequentially added substrate wetting agent (750, Shenzhen Simequan Biotechnology Co., Ltd.) 1g, 1g foaming agent (Foamex 825N, Tego), 1g rheology additive (881-B, Qinghong), stir at room temperature for 10 minutes to obtain Part A, when using, add 5% curing agent (XP -2700, Bayer), fully stirred to obtain the environmentally friendly water-based polyurethane adhesive for plastic sites.

Abstract

The invention relates to an environment-friendly waterborne polyurethane adhesive used for a plastic ground and a preparation method thereof and belongs to the technical field of polyurethane application. The environment-friendly waterborne polyurethane adhesive used for the plastic ground is prepared from the following raw materials in percentage by weight: 40-68% of waterborne polyurethane resinA, 30-55% of waterborne polyurethane resin B, 0.1-1% of a base material wetting agent, 0.1-1% of a defoaming agent, 0.1-1% of a rheological agent and 1-9% of a curing agent; and the waterborne polyurethane resin A and B are one of aliphatic series anionic polyurethane waterborne dispersions with the solid contents of 30-70% and 20-40% respectively. The environment-friendly waterborne polyurethaneadhesive used for the plastic ground has the characteristics of long pot life, high strength, rapidness in curing, excellent hardness and toughness, good substrate adhesive strength, simple operation, convenience in construction and environmental friendliness; and the invention also provides a scientific, reasonable, simple and easy preparation method.

Description

Technical field [0001] The invention relates to an environmentally friendly water-based polyurethane adhesive for plastic sites and a preparation method thereof, and belongs to the technical field of polyurethane applications. Background technique [0002] With the public's attention to the safety of campus sports facilities, healthy and environmentally friendly water-based sports products have broad application prospects. In order to protect the health of teenagers and children and improve their physical fitness, a series of water-based polyurethane environmentally friendly track products came into being. The main components of this product are water-based polyurethane resin emulsion and various functional additives. [0003] CN102733289A discloses a water-based acrylic resin plastic track and a production method thereof, comprising a base layer, a shock absorption layer, a wear-resistant layer and a cover protective layer which are sequentially bonded together from bottom to top,...
