Traditionally, water-based resins include water-soluble resins and water-dispersible resins.
Each has its own characteristics. For example, water-soluble resins include an anionic type in which carboxyl groups are neutralized and dissolved with an alkali such as ammonia or amine, and a cationic type in which tertiary amino groups are neutralized and dissolved in an acid.They have workability comparable to organic solvent-based resins. However, since 30 to 50% by weight of organic solvents are used in the paint, there remain problems in terms of pollution control, as well as odor, dryness of the paint film, and It has the disadvantage of poor water resistance. Furthermore, as the molecular weight of the polymer increases, the viscosity also increases, so there is a drawback that those containing high molecular weight polymers cannot be used.

On the other hand, water-dispersible resins produced by emulsion polymerization in the presence of emulsifiers and protective colloids, or water-dispersible resins obtained by mechanical dispersion, have high concentrations and relatively low viscosity, regardless of molecular weight. However, the water resistance of the coating film is affected by the emulsifiers, protective colloids, etc. used.
It has drawbacks such as poor corrosion resistance and poor adhesion to substrates.

In order to solve the above-mentioned problems, the present inventors conducted extensive studies and found that a tertiary amino group was introduced into the polymerization reaction system, and a polyalkylene glycol was further added to the resulting polymer in a water-soluble solvent solution. By adding it to water and dispersing it, a resin dispersion that is stably dispersed without using an emulsifier or a binder can be obtained, and a coating film made of these water dispersions as a pigment binder component has water resistance, It has been confirmed that it has excellent corrosion resistance and adhesion, especially to bituminous substrates such as asphalt 1 concrete used for roads, tennis courts, floors, etc., and tar, which is used in large quantities as a waterproofing material. This led to the present invention.

The four-oil dispersion of the present invention can be of cationic or amphoteric type, and the cationic and amphoteric types have excellent adhesion to anionic components in the base material of the object to be coated, that is, undercoating,
Since it has good adhesion to the anionic filler, pigment, etc. in the binder contained in the top coat, it has the advantage that the adhesion of the finishing agent applied thereon is also improved. Note that the amphoteric type can be used in a wide pH range of 1ilW, and has less selectivity to the substrate in terms of adhesion.Of course, the fact that the dispersion is soap-free also increases the adhesion effect to the substrate. ing.

The reason why the above-mentioned tertiary amino group-containing α,β-unsaturated ethylenic monomer is 2 to 35 parts by weight is that if it is less than 2 parts by weight, water dispersibility is insufficient and fucationicity is decreased, so that it may not adhere to the ethylenic monomer. In addition, when used in excess of 35 layers, hydrophilicity becomes high, water resistance decreases, and water solubility is high, making it difficult to obtain a stable dispersion. In particular, it is more preferable in consideration of adhesion to N bone base materials such as asphalt and tar.

Examples of the polyalkylene glycol include one or more of polyethylene glycol, polypropylene glycol, and a block copolymer of polyethylene glycol and polypropylene glycol. The amount used is 1 to 2 parts by weight per 100 parts by weight of the unsaturated monomer, depending on the balance between the dispersibility imparting effect of the resin and the water resistance of the coating film, etc.2.
It should be 0 parts by weight. If the amount used is 1 part by weight or more, there is an advantage that water dispersion is possible without neutralization, but 2
If it exceeds 0 parts by weight, the efficiency of grafting will hardly increase and the water resistance will decrease. On the other hand, if it is used in an amount less than 1 weight, it will hardly contribute to the dispersion effect, and if the molecular weight is less than 600, the dispersion effect will not be sufficient due to poor hydrophilicity, while if it exceeds 20,000, it may cause grafting with the vinyl copolymer. Fusion with the polymer is also difficult to occur and the dispersion effect is not improved.

As for the water-soluble solvent, it is desirable to select one that has the ability to dissolve polymers and has an effect on the retraceability of application (waxing, sagging, drying properties, etc.) after being made into a paint. For example, methanol,

The amount used is 20 to 1 part by weight per 100 parts by weight of resin solid content.
00 parts by weight is desirable. If the amount is less than 20 parts by weight, the viscosity of the solution will increase during the reaction, which will hinder the polymerization reaction, and if it exceeds 100 parts by weight, the viscosity of the resin dispersion will increase and the dispersion stability will decrease, making it even more resource-saving. It also goes against the grain. More preferably 30ffi amount % in the final resin dispersion
The value δ1 should be set to be below. After dispersion, it is also possible to further reduce the amount of the low boiling point water-soluble solvent by vacuum distillation or the like. The polymerization reaction may be a conventional solution polymerization reaction method and is not particularly limited. These polymerizations are preferably carried out at 50 to 150°C in the presence of polyalkylene glycol and a radical polymerization initiator. As the radical polymerization initiator, oil-soluble radical polymerization initiators such as azobisisobutyronitrile, azobisvaleronitrile, benzoyl peroxide or t-butyl hydroperoxide are used.

The water-soluble solvent solution of the polymer resin thus obtained is then dispersed in water to obtain a resin dispersion. Dispersion of the polymer resin solution in water is achieved by adding the resin solution to water and dispersing the resin. This may be a method of dispersion, or a method of injecting water into the resin solution and dispersing it. In either case, the system is heated to 50 to 100°C, and the mixture is gradually stirred. It is desirable to add and disperse the amount.
