In recent years, vinyl chloride plastisol (hereinafter referred to as "PVC sol") has been used instead of the conventional bituminous undercoat material for the undercoat, side seals, fuel tanks, front aprons, and tire houses of automobiles to protect them from damage caused by flying stones. A coating material called chipping-resistant paint is generally applied using an airless coating device.

充填材を使用した技術は未だ提案されていない。 In addition, as a technique for using hollow fillers, hollow fillers are exemplified as filler components in baking-type soundproofing paints consisting of rubber components and filler components (JP-A-55-58261 et al. A hollow material is exemplified as a filler in a rubber asphalt emulsion in a soundproofing/vibration proofing method in which a rubber asphalt emulsion and a coagulant composition are applied (Japanese Patent Laid-Open No. 60-87879). There is only technology,
No technique has yet been proposed in which a filler is used in a hollow shape for the purpose of reducing the weight of chipping-resistant paint.

On the other hand, in order to extend the service life of vehicles and improve the level of rust prevention requirements, there has been a growing market need to expand the coating area and increase the coating thickness of the above-mentioned vinyl chloride sol-based chipping-resistant paint. However, such measures have the problem of increasing the weight of the existing vehicle, deteriorating driving performance, and going against the energy savings achieved by reducing the weight of the vehicle.

The inventors of the present invention have conducted intensive research to find a chipping-resistant paint that can be made lighter without reducing the chipping-resistant performance per unit coating amount. 1 to 50% by weight of the filler components used in PVC sol-based chipping-resistant paints are hollow fillers listed as filler components for vibration materials that have a compressive strength of 120 kg/cm 2 or more. , preferably 3 to 30% by weight, it has surprisingly been found that a chipping-resistant paint for vehicles can be obtained which completely solves the above problems and has excellent suitability for airless spray coating.

The hollow filler has a lower specific gravity than the filler used in conventional chipping-resistant paints, so the specific gravity of the chipping-resistant paint as a whole is 1.35 to 1.55.
1.05 to 1.15, which is a decrease of 0.3 to 0.5.
また、従来から使用の充填材成分の１〜50重量

合は全くない。 Moreover, there is no problem that the inherent performance of the chipping-resistant paint is degraded due to replacing 1 to 50% by weight of the conventionally used filler components with hollow fillers.

Vinyl chloride plastisol is made by dispersing vinyl chloride resin in a plasticizer and adding fillers and additives. Preference is given to using homopolymers, copolymers of vinyl chloride, vinyl acetate, vinylidene chloride, and the like.
可塑材としては、フタル酸エステル、二塩基性
酸エステル、燐酸エステル、ポリエステル系可塑

低下する虞れがある。 In the present invention, it is essential to replace 1 to 50% by weight of the total filler with hollow fillers; if less than 1% by weight is replaced, the weight reduction effect will be diminished, and if more than 50% by weight is replaced, There is a possibility that the chipping resistance performance will deteriorate.

れないくらいの強度を必須とする。 The hollow filler used in the present invention is used for applying chipping-resistant paint by airless spraying.
It must have a strength of about 120 kg/cm 2 at least enough to prevent the hollow filler from collapsing.

い。 The hollow filler can be used as long as it has a particle size of 300μ or less, and preferably 95% of the total size per 100 meshes.
% (approximately 150μ or less) is sufficient. If the particle size is too large, there is a risk that the pattern width of the airless spray will vary, gun clogging may occur, and the finished surface may become rough. Furthermore, if the particle size is too small, the compressive strength will decrease and the weight reduction effect will not be achieved, so it is better to avoid this as much as possible.
中空状充填材の嵩比重は0.1〜0.4であれば使用
可能であり、好ましくは0.2〜0.3である。即ち、
中空状充填材は強度が伴なえば嵩比重は小さい方
がより好ましい。 The hollow filler can be used if it has a bulk specific gravity of 0.1 to 0.4, preferably 0.2 to 0.3. That is,
It is more preferable for the hollow filler to have a small bulk specific gravity if it has good strength.
