Description
Technical Field
The invention relates to a metal-textured two-component polyurethane adhesive for an environment-friendly permeable pavement and application thereof in the field of building materials, and belongs to the technical field of organic chemical synthesis.
Background
Along with the urbanization process, urban pavements are covered by more and more impervious buildings, pavements and the like, so that people can go out conveniently, but the urban heat island effect is caused, and urban waterlogging and flood control dangers are increased. When raining, the impervious pavement causes precious water resources to slide away along with the drainage pipeline, and a large amount of rainwater is lost, so that a series of ecological and environmental problems are caused. And the phenomenon can be greatly relieved by paving the permeable pavement in the city.
In recent years, a plurality of patents related to the invention of permeable pavement materials and application, such as Chinese patent CN108300400A, propose an environment-friendly two-component polyurethane adhesive taking vegetable oleic acid as a main component A and isocyanate as a component B, and the adhesive is applied to permeable pavements and has better mechanical properties and water permeability; chinese patent CN105967729A discloses a road surface water permeable composite material, which can realize the functions of water purification and water storage by filtering and permeating water through a surface micron-sized pore filter layer. However, many patents related to permeable pavement materials focus on the invention of performance and formula, and less attention is paid to the aspect of combining road surface aesthetics and environmental protection, even if a few colored environment-friendly pavements appear, such as the environment-friendly colored permeable pavement mentioned in chinese patent CN204825547U, a colored permeable layer formed by laying dyeing or mixing natural colored macadam and adhesive on the surface layer is also adopted, so that two disadvantages exist, one is that if the dyeing method is adopted to color the original natural macadam to obtain the colored macadam, the problems of solvent use and environmental pollution exist; secondly, if the natural colored macadam is directly adopted, the problems of single color, deficient mineral resources, low yield and high cost exist.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a two-component polyurethane adhesive with metal texture for an environment-friendly permeable pavement, the adhesive does not contain a solvent, a vegetable oil reaction raw material and polyester polyol are mixed to be used as a main body of an A adhesive, and the main body is cured with B adhesive isocyanate under the action of a catalyst to obtain the polyurethane adhesive, and the produced adhesive has the advantages of high adhesiveness, metal texture, colorful color and luster and the like, and is simple to produce and prepare.
Meanwhile, the invention also provides a preparation method and application thereof, and the preparation method is scientific, reasonable, simple and easy to implement.
The invention relates to a metal-textured bi-component polyurethane adhesive for an environment-friendly permeable pavement, which comprises a component A and a component B, and the component A comprises the following components in percentage by mass:
the component A comprises: total 100 percent
The component B comprises: is 50 to 85 percent of the component A by mass
Isocyanate: 55-80 percent
Wherein, the polyester polyol is oligomer which is formed by polycondensation of phthalic anhydride and diethylene glycol as raw materials, and the polyester polyol has the functionality of 2 and the hydroxyl value (mgKOH/g) of 100-200.
If the functionality of the polyester polyol is less than 2, the polyester polyol cannot undergo chain extension when participating in polymerization as a soft segment, which is disadvantageous in increasing the molecular weight of the polyurethane polymer and forming a polymer network. If the functionality is more than 2, a branched structure is easily formed in the polymerization reaction, and the molecular weight is hardly increased, resulting in low properties such as mechanical strength. And is therefore limited to 2. The polyester polyol having a hydroxyl value within the range of 100-200 is most compatible with the vegetable oil (castor oil).
The isocyanate is one or two of 4,4 '-diphenylmethane diisocyanate and polymeric 4, 4' -diphenylmethane diisocyanate.
The polymeric 4, 4' -diphenylmethane diisocyanate is also called polymethylene polyphenyl polyisocyanate, is an oligomer of MDI, is called polymeric MDI for short, and is brown transparent liquid.
The vegetable oil is castor oil or epoxidized soybean oil, and is preferably castor oil.
The aluminum flake pigment subjected to coating treatment is an aluminum flake pigment subjected to silicon dioxide coating treatment or an aluminum flake pigment subjected to silicon dioxide/polymer double-layer coating treatment; and aluminum sheet pigments coated with inorganic ferric chloride, organic indigo dye, etc. and with different colors, such as gold, yellow, blue, etc.
The preparation method of the aluminum metal flake pigment coated with the silicon dioxide refers to the self-made Chinese patent CN106752121B, the preparation method of the aluminum metal flake pigment coated with the silicon dioxide/polymer double layer refers to the self-made Chinese patent CN107383943A, and the coating methods of various colors such as gold aluminum metal flake pigment refer to the U.S. Pat. No. 3, 20110197782, 1.
The chain extender is one or more of Trimethylolpropane (TMP), diethylene glycol, 1, 4-butanediol, propylene glycol, 1, 4-cyclohexanediol and glycerol, and is preferably a compound of 1, 4-butanediol and trimethylolpropane (the molar ratio is 1 (2-4))
The catalyst is an organic tin catalyst.
The two-component polyurethane adhesive with metal texture is characterized in that the ultraviolet absorbent is one selected from Sumisorb140, Sumisorb220, Sumisorb300, Sumisorb320 and Sumisorb 400.
The preparation method of the bi-component polyurethane adhesive for the environment-friendly permeable pavement with metal texture comprises the following steps:
preparation of component A: firstly, vegetable oil, polyester polyol, aluminum sheet pigment subjected to coating treatment and a chain extender according to the formula amount are put into a reaction kettle to be stirred for 35-50 minutes, and simultaneously, the temperature is raised to 80-90 ℃. And dehydrating under the vacuum degree of-0.1 MPa, stopping heating, cooling to below 50 ℃, adding an ultraviolet absorbent and a catalyst, and stirring for 15-35 minutes to obtain the component A.
Before use, the A, B components are respectively packaged, and when in use, the A, B components are fully mixed and uniformly stirred according to the mass ratio to obtain the polyurethane adhesive.

The purpose of adding the polyester polyol is to adjust the molecular chain structure of the polymer and increase the performances of the polyurethane adhesive such as temperature resistance, hardness and the like after the synergistic effect of the polyester polyol and the vegetable oil.
Besides the metallic texture and colorful color of the product, the aluminum flake pigment coated with silicon dioxide can generate synergistic action when the A, B glue is solidified. Specifically, the aluminum metal flake pigment coated with silicon dioxide is a micron-sized two-dimensional flake material, and the surface of the aluminum metal flake pigment contains hydroxyl functional groups, so that the aluminum metal flake pigment can be bonded with isocyanate groups to increase the mechanical strength of the polyurethane adhesive; secondly, because the heat conductivity coefficient of the aluminum metal flake pigment is larger, after the aluminum metal flake pigment is added, the aluminum metal flake pigment can more quickly transfer heat to the inside under the same reaction temperature condition, so that the curing time is reduced.
Compared with the prior art, the invention has the following beneficial effects:
