Description

Technical Field

[0001] This invention belongs to the field of permeable pavement materials, specifically relating to a triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive, its preparation method, and its application. Background Technology

[0002] Permeable bonded stone is made by mixing and curing adhesives with natural colored stones. It is characterized by its sturdiness, beauty, natural color, and high permeability. Currently, there are two main types of adhesives for permeable bonded stone: epoxy and polyurethane. Epoxy adhesives have high strength, but their flexibility and weather resistance are slightly worse, and stones are prone to falling off after long-term use. Polyurethane adhesives have good weather resistance, but they have higher requirements for the construction environment.

[0003] Meanwhile, existing permeable adhesives for bonding stone have a slow drying speed after application, requiring at least 4-8 hours to reach surface dryness, and opening to traffic generally takes even longer, affecting the construction efficiency of some emergency road construction projects. For example, Chinese patent CN112723790A uses epoxy resin combined with organic amine curing, and through formula optimization, the surface drying time is reduced to 4 hours; Chinese patent CN112457816A uses HDI curing agent combined with a polyol system, shortening the road opening time to 4-5 hours. Summary of the Invention

[0007] Component B is a mixture of bisphenol A type epoxy resin and glycidyl methacrylate;

[0008] Component C is a mixture of polyetheramine, reactive diluent, photoinitiator and short-cut carbon fibers;

[0010] In this invention, the fluorinated polyurethane acrylic oligomer of component A has a structure as shown in general formula (1):

[0011] D-(PD)nF(1)

[0012] In the formula:

[0013] D represents residues derived from diisocyanate monomers;

[0014] P represents residues derived from polyether polyols;

[0015] F represents a residue derived from a fluorinated hydroxy acrylate monomer.

[0016] In component A of the present invention, in the structure shown by general formula (1), the diisocyanate monomer is selected from any one or a combination of at least two of dicyclohexylmethane diisocyanate (HMDI), isophorone diisocyanate (IPDI), and hexamethylene diisocyanate (HDI);

[0019] In this invention, the fluorinated polyurethane acrylic oligomer is prepared by reacting diisocyanate monomer, polyether polyol, and fluorinated hydroxyl acrylic monomer at 40-80°C for 3-9 hours, preferably 4-8 hours.

[0020] Preferably, the mass ratio of the diisocyanate monomer to the polyether polyol and the fluorinated hydroxyl acrylic monomer is 1:0.5 to 5:0.2 to 0.5, for example 1:0.6:0.25, 1:1:0.34, 1:1.5:0.38, 1:3:0.45, and more preferably 1:0.7 to 2:0.3 to 0.4.

[0022] More preferably, the amount of catalyst used is 10 to 50 ppm, for example 20 ppm, 30 ppm, or 40 ppm, based on the mass of the polyether polyol.

[0024] In component B of the present invention, the epoxy equivalent (EEW) of the bisphenol A type epoxy resin ranges from 170 to 190, preferably from 175 to 185.

[0031] In component C of this invention, the mass ratio of the polyetheramine, reactive diluent, photoinitiator, and chopped carbon fiber is 1:0.4-0.7:0.1-0.5:0.1-0.4, preferably 1:0.5-0.65:0.2-0.4:0.15-0.25.

[0032] This invention also provides a method for preparing the above-mentioned triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive, the steps of which include:

[0033] 1) Preparation of component A: For example, prepare the fluorinated polyurethane acrylic oligomer according to the above method, for later use;

[0034] 2) Preparation of component B: Mix bisphenol A epoxy resin and glycidyl methacrylate evenly and set aside.

[0035] 3) Preparation of component C: Mix polyetheramine, reactive diluent, photoinitiator, and short-cut carbon fibers evenly and set aside;

[0036] 4) When using, mix components A, B, and C evenly to obtain the triple-curing, fast-drying polyurethane modified epoxy permeable pavement adhesive.

[0037] In another aspect, the present invention also provides the application of the above-mentioned triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive.

[0038] As a preferred embodiment, the present invention provides a permeable adhesive stone pavement material, the raw material of which includes the triple-curing fast-drying polyurethane modified epoxy permeable pavement adhesive described in the present invention.

[0039] Preferably, the triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive has a mass content of 2-7%, more preferably 3-5%, based on a total mass of 100% for the permeable adhesive stone pavement material;

[0040] As a preferred embodiment, the permeable adhesive stone pavement material comprises the following raw materials by weight:

[0041] 93-98 parts of pebbles, preferably 95-97 parts;

[0042] 2-7 parts of triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive, preferably 3-5 parts.

[0043] The construction method of the permeable adhesive stone pavement material of the present invention includes the following steps:

[0044] First, mix the above components A, B, and C evenly to obtain a triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive. Then, mix it thoroughly with the stones and lay it on the road surface to be constructed. Finally, use ultraviolet light equipment to irradiate and cure the surface.

[0045] Preferably, the irradiation power of the ultraviolet light device is 6-8W, and a handheld long-wave ultraviolet lamp is preferred, with a wavelength of 325-365nm, and more preferably 325nm or 365nm lamp tubes.

[0046] The surface drying time of the permeable adhesive stone pavement material described in this invention can be reduced to less than 5 minutes, allowing passage immediately after construction.

[0047] The triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive of this invention innovatively employs a three-component adhesive curing system. Component A contains NCO groups and unsaturated double bonds, component B contains epoxy groups and unsaturated double bonds, and component C contains amine groups and unsaturated double bonds. After construction, the system exhibits a triple curing mechanism: free radical polymerization containing double bonds, the reaction between epoxy groups and amine groups provided by epoxy resin and glycidyl methacrylate (GMA), and the reaction between NCO groups and amine groups. Due to the presence of unsaturated double bonds, preliminary cross-linking can be rapidly achieved upon UV irradiation after construction, resulting in a surface-dry pavement layer with sufficient strength, dust-free operation, and pedestrian strength requirements, significantly improving pavement construction efficiency. Furthermore, within the adhesive layer untouched by UV light, the dual curing effect of the epoxy and polyurethane systems allows for a rapid and exothermic reaction between NCO groups and the primary amine in the polyetheramine, further accelerating the curing of the epoxy and amine and effectively shortening the required drying time of the adhesive layer. This multi-curing effect effectively enhances the adhesive layer strength and increases the drying speed. The three-component curing system can effectively link polyurethane and epoxy molecular chains through double-bond free radical polymerization, giving the cured adhesive layer superior weather resistance and toughness.

[0048] Furthermore, the adhesive of this invention introduces fluorine groups into the main chain of the fluorinated hydroxyl acrylic monomer in component A, and at the same time, the short-cut carbon fibers added in component C effectively improve the hydrophobicity of the adhesive layer surface. The short-cut carbon fibers can serve as the adhesive layer skeleton, and at the same time, they can effectively reduce the gas generated by the reaction of isocyanate groups with water in the system, thereby reducing the number of microbubbles in the adhesive layer. Experimental verification shows that this can greatly improve the strength of the adhesive layer and its long-term water resistance.

[0049] Compared with existing technologies, the triple-curing, fast-drying polyurethane-modified epoxy permeable pavement adhesive of the present invention has a fast drying speed, high strength, excellent weather resistance and long-term water resistance, which can effectively improve the construction efficiency of permeable pavement in sponge cities and has broad application prospects.
