Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an aqueous dispersion of polyester resin. More specifically, the present invention relates to an aqueous dispersion of a polyester resin with a small particle size that can form a film with excellent water resistance and weather resistance.

(Prior art) Organic abrasion has traditionally been widely used in various processing fields such as paints, inks, coatings, adhesives, textile products, and paper, but in recent years organic abrasion has been widely used in the field of processing various materials such as paints, inks, coating agents, adhesives, and textile products and paper. From the viewpoint of prevention, the use of III-III solvents is becoming extremely difficult. Therefore, various methods are used, for example, 1) high solid type, 2) non-aqueous dispersion type,
3) water-based dispersion type, 4) emulsion type, 5) solvent-free type, etc. have been proposed and many of them are already in use. Among these, the water-based dispersion type is the most versatile because of its ease of handling, and the
being watched.

On the other hand, many of the resins currently used are hydrophobic;
A major issue is how to disperse or make it aqueous in water. Furthermore, it is also an important issue whether water resistance or weather resistance can be imparted to a film formed from a resin that has been imparted with an affinity for water by some method. These technical solutions are common to any resin, and polyester resin is no exception.

Already, methods for dispersing polyester resins in water or making them water-soluble include copolymerizing hydrophilic raw materials, such as copolymerizing raw materials containing sulfonic acid metal bases, polyalkylene glycols, aliphatic dicarboxylic acids, etc. alone or in combination. Polymerization methods are known. However, in either method, a large amount of the above-mentioned hydrophilic raw materials are required to provide excellent water solubility or dispersibility, and the resulting film has very poor water resistance and weather resistance. becomes.

For example, in Japanese Patent Publication No. 47-40878, in order to sufficiently dissipate in water, 8 mol% or more of a sulfonic acid metal base-containing compound based on the total acid component and 20 mol% or more of polyethylene glycol based on the total glycol component are required. It is stated that it is necessary to use

It is easy to imagine that such polyester resins have poor water resistance and weather resistance. That is, the fact that it can be sufficiently dissipated in water means that the film formed after drying has poor water resistance. In this case, when the film comes into contact with water, not only does its adhesion deteriorate, but also the hue changes, making it unsuitable for use with paints, inks, coatings, adhesives, etc. Furthermore, the use of a large amount of polyethylene glycol significantly reduces not only water resistance but also weather resistance.

On the other hand, it is well known that the use of a large amount of aliphatic dicarboxylic acid deteriorates the mechanical properties of polyester resin.

Unless the conflicting problems of imparting properties such as imparting hydrophilicity, water resistance, and weather resistance are overcome, it will not be practical.

Water-based polyester resins have been proposed as resins that overcome these problems (Japanese Patent Laid-Open Publication Nos. 56-35547, etc.).

However, although these polyester resins have excellent adhesion and water resistance, when applied using a roll coater, the coating liquid transferred to the roll dries, forms a film, and then falls off into the coating liquid reservoir. It often happens. There is no problem if the fallen fragments are smoothly redissolved in the coating liquid, but since these polyester resins have excellent water resistance, they are difficult to redissolve. As a result, it is not always possible to obtain good coating stability, and there may be restrictions on the development of these resins. Some proposals have been made to use them in combination to improve stability, but only films with poor water resistance are obtained, and there is no water-based polyester resin that achieves both coating stability, adhesion, water resistance, etc.

(Problems to be Solved by the Invention) The present inventors have conducted intensive research and efforts to obtain a water-based resin that has excellent properties in terms of coating stability, adhesion, and water resistance, which address the problems in the conventional technology. This led to the completion of the present invention.

The molecular weight of the resulting polyester resin is preferably 1.000 to 100.000.

If the molecular weight is less than 1,000, the cohesive force of the polyester resin will be low, resulting in poor adhesion to the support.

Moreover, the molecular weight is 100. If the OQO is exceeded, a disadvantage arises in that dissolution (dispersion) in an aqueous medium, which will be described later, becomes difficult.

The concentration of other hydrophilic polar groups is less than 4,000 eq per 10" g of polyester resin, preferably 10 to 3.0 OOeq. More preferably 20
~1,000 eq. Polar group concentration is 3.0OOe

] must be satisfied. If the polyester resin (A) exceeds 80, it will be difficult to dissolve (disperse) in an aqueous medium, and if it is less than 1, the adhesion to the substrate will deteriorate. If the content of compound (B) that satisfies formula 1) exceeds 40, the viscosity of the composition will be very high, making it impossible to obtain a coating film of uniform thickness, and if it is less than 2% by weight, the dried coating film will not be redissolved. It becomes defective.

When water (C) is less than 5, good dissolution (dispersion) becomes difficult. To obtain an aqueous dispersion, it is necessary to dissolve, disperse, and emulsify the above-mentioned polyester resin having a polar group in an aqueous medium. For example, in the case of the polyester resin obtained by reacting in a solvent-free environment, the resin and a compound satisfying formula 1) are warm mixed at 50 to 150°C, and water is added to this mixture and dispersed by stirring. Alternatively, there is a method in which the mixture is added to water and stirred to dissolve and disperse, or a method in which the resin and water, if necessary, a compound satisfying formula 1) are made to coexist and stirred at 40 to 120°C.

In the case of the polyester resin obtained by reacting in a solvent, for example, water and, if necessary, a compound satisfying formula 1) are added to the resin solution, the system is reduced in pressure, and the solvent is removed from the system by azeotropy. remove it. In the method of obtaining these aqueous dispersions, an alkaline or acid neutralizing agent, a surfactant, etc. may be used if necessary.

In addition to the above-mentioned water-soluble compounds, there are also organic compounds having a solubility in water of 20 g or more at 20°C, such as aliphatic and alicyclic alcohols, ethers, esters, and ketone compounds, such as methanol, ethanol, and isopropanol. tools, monohydric alcohols such as n-butanol, glycols such as ethylene glycol and propylene glycol, glycol derivatives such as methyl cellosolve, ethyl cellosolve, and n-butyl cellosolve, ethers such as dioxane and tetrahydrofuran, and esters such as ethyl acetate. Ketones such as , methyl ethyl ketone, etc. can be used alone or in combination of two or more.

Any known coating method can be used to coat the aqueous polyester resin of the present invention onto a support and the aqueous dispersion of the present invention onto a support. For example, roll coating method, gravure coating method, roll plush method, spray coating,
It is recommended to apply air knife coating, impregnation, curtain coating, etc. independently or in combination. Materials for the support to be coated include, for example, polyesters such as polyethylene terephthalate, polyolefins such as polypropylene, cellulose triacetate, cellulose diacetate, etc. Cellulose derivatives, polycarbonate,
Examples include polyvinyl chloride, polyimide, metals such as aluminum and copper, and paper. It is also permissible to apply the coating and, after drying, to subject the coating film to heat treatment or radiation treatment. These treatments are intended to improve the durability of the coating film through crosslinking.

If necessary, the crosslinking side of melamine resin, epoxy resin, polyfunctional isocyanate compound, polyfunctional acrylate compound, etc. may be added to 50g per 100g of polyester resin solid content.
It is possible to use the ratio below. If it exceeds 50 g, the excellent adhesiveness and flexibility of the polyester resin will be lost, which is not preferable. As radiation, electron beam, γ
rays, neutron beams, beta rays, X-rays, and ultraviolet rays. Furthermore, if necessary, stabilizers, leveling agents, coloring materials such as pigments, and even other aqueous resins may be used in combination, and these may be used in accordance with each purpose.

(Function) In the present invention, by using a polyester resin obtained by reacting a compound containing a sulfonic acid metal base or a phosphorus base as a raw material for an aqueous dispersion, adhesion to a support and water resistance are impaired. Coating stability can be imparted without any problems.
