Description
Technical Field
The invention relates to the field of building materials, in particular to a permeable concrete environment-friendly protective agent and a preparation method thereof.
Background
The urbanization process of china has advanced dramatically since the 21 st century. More and more urban ground surfaces adopt ecological and environment-friendly permeable pavements to solve the urban heat island effect, the permeable pavements are paved by permeable concrete,
the excellent characteristics of ventilation, water permeability, cooling, noise reduction and comfortable walking make the permeable concrete an indispensable auxiliary material in the garden landscape road. However, after the pervious concrete is dried, because the internal cohesive force of the pervious concrete is weak, certain broken particles are generated on the surface due to abrasion in use after the pervious concrete is used for a period of time, the performance and the service life of the concrete pavement are seriously influenced, the attractiveness of the pavement is reduced by the concrete particles dispersed on the ground, and the overall visual impression of landscape is influenced, so that a layer of protective agent needs to be attached to the surface of the pervious concrete, and the service life of the concrete pavement is prolonged. Most of the existing permeable concrete protective agents are oil coatings, the oil coatings mostly adopt organic solvents such as benzene, toluene, xylene and derivatives thereof as diluents, and the components can cause considerable air pollution after being evaporated into air and even can damage the atmosphere in severe cases. In addition, most of the oil-based coatings are polyurethane coatings, toluene diisocyanate is often added as a curing agent, and the toluene diisocyanate is a 2B carcinogen, so that the use of the oil-based coatings as concrete protective agents seriously harms human health. Finally, the content in the oil paint is mostly flammable and explosive liquid, and the probability of major accidents in the process of storage and transportation is high. Therefore, in summary, a new pervious concrete protectant which is environmentally friendly, harmless to human body and high in safety factor of storage and transportation is urgently needed in the existing pervious concrete maintenance process.
Disclosure of Invention
The invention aims to solve the technical problem of providing an environment-friendly pervious concrete protective agent, and overcomes the defects that the existing pervious concrete protective agent on the market has high content of volatile organic compounds, is easy to cause harm to the atmospheric environment and human health, and is flammable and explosive.
In order to achieve the purpose, the invention adopts the technical scheme that: the permeable concrete environment-friendly protective agent is prepared by mixing 50-65% of aqueous polyurethane acrylate resin dispersoid, 8-20% of deionized water, 0.5-2% of aqueous dispersant, 1.5-4.5% of film-forming agent, 0.2-0.5% of ammonia neutralizer, 0.3-0.6% of aqueous defoamer, 0.5-2.0% of thickening agent and 7-25% of aqueous color paste.
Further, the weight percentage of each component is 65 percent of aqueous polyurethane acrylate resin dispersoid, 12 percent of deionized water, 0.5 percent of aqueous dispersant, 4 percent of film forming agent, 0.2 percent of ammonia neutralizer, 0.3 percent of aqueous defoamer, 2.0 percent of thickening agent and 16 percent of aqueous color paste.
Preferably, the aqueous dispersant is sodium N- (2-aminoethyl) aminoethane sulfonate.
Preferably, the ammonia neutralizing agent is dimethylethanolamine.
Preferably, the aqueous defoamer is a polysiloxane.
Preferably, the film former is an alcohol ester twelve.
Preferably, the thickener is a polyurethane associative thickener.
The invention also provides a preparation method of the pervious concrete environment-friendly protective agent, which comprises the following steps:
1) under the condition of stirring, sequentially adding deionized water, a water-based dispersant, a water-based defoamer, an ammonia neutralizer and a thickening agent into a mixing kettle, and stirring and mixing;
2) sequentially adding the aqueous polyurethane acrylate resin dispersoid and the aqueous defoaming agent into the mixture in the step 1), and stirring and mixing;
3) adding a film forming agent and a thickening agent into the mixture obtained in the step 2), using water-based color paste for color mixing, finally supplementing proper deionized water to adjust the viscosity, and stirring and mixing uniformly.
Compared with the prior art, the invention has the following beneficial effects:
the permeable concrete environment-friendly protective agent takes the aqueous polyurethane acrylate resin dispersoid as a main component, and adopts deionized water to mix the main component with other water-soluble additives, thereby overcoming the defects that the existing permeable concrete protective agent on the market has high content of volatile organic compounds, is easy to generate harm to the atmospheric environment and human health, and is flammable and explosive.
Secondly, in the invention, acrylic ester is introduced into the aqueous polyurethane dispersion chain segment in an acrylic resin copolymerization mode to modify the aqueous polyurethane, thereby preparing the permeable concrete aqueous paint protective agent with excellent performances in all aspects. The acrylic ester has the advantages of outstanding flexibility, excellent light resistance, strong chemicals and the like, but the acrylic ester is generally in a chain linear structure, belongs to a thermoplastic high polymer material, is sensitive to temperature, and has poor moisture-proof cold and hot cycle performance of a coating, and the thickening performance of a polyurethane dispersion is poor, so that the water resistance of a paint film is insufficient, and the water-based acrylic ester and polyurethane composite emulsion can complement the advantages of high tensile strength and impact strength of polyurethane, excellent wear resistance, good adhesive force of the acrylic ester, weather resistance and acid and alkali resistance, so that the optimal paint film performance is developed, and the performance requirements of water-permeable concrete on environmental protection, weather resistance, adhesive force and acid and alkali resistance are met.
The film-forming agent alcohol ester twelve is a dihydric alcohol water-insoluble solvent, is a good solvent of the emulsion polymer, and can reduce the low film-forming temperature of the polymer and slow volatilization. It can impart a number of excellent properties to the coating, such as: scrub resistance, color development, packaging stability in paint, etc. As a film forming aid, and also has good hydrolytic stability, and can be used in many different types of emulsions, including high PH acrylic emulsions. After the alcohol ester dodeca is added to the emulsion coating, it is adsorbed by the polymer latex particles, softening them and thus completing the fusion during the drying of the paint film. The alcohol ester dodeca is insoluble in water and thus is not in the water phase, so that when the paint is coated on a porous substrate, the alcohol ester dodeca cannot be absorbed together with water, the film forming effect cannot be reduced, and the film forming effect and the paint prepared by the paint have unique storage stability, leveling property and adhesive force and can improve the gloss.
