は耐熱性が不充分である。However, since olefin polymers are nonpolar, they have extremely poor adhesion to metals. In order to improve this drawback, it is widely known to graft or copolymerize an olefin polymer with a monomer containing a polar group. (Japanese Patent Application Laid-open No. 108645/1983,
JP-A No. 155242, JP-A No. 55-118
(See Publication No. 975, Japanese Unexamined Patent Publication No. 59-80841, etc.)
However, even with these graft modified products or copolymers, it is difficult to say that metal adhesion is sufficient for practical use, and some metal products may be used at high temperatures, such as hot water pipes and peripheral parts of automobile engines. An ethylene-based monomer has insufficient heat resistance.

膜の伸びが極めて乏しいため金属基材の変形加工あるい
は衝撃による変形などにより塗装膜が破断し、本来の防
錆、保護の目的が達せられないという難点がある。Some propylene-based polymers have excellent heat resistance, but because the paint film has extremely poor elongation, the paint film can break due to deformation of the metal substrate or deformation due to impact, and the original purpose of rust prevention and protection is lost. The problem is that it cannot be achieved.
本発明は、上記の難点を解決し、金属との接着強度が大

得る粉体塗料用樹脂組成物を提供するものである。The present invention solves the above-mentioned difficulties and provides a resin composition for powder coatings that can form a coating film that has high adhesive strength with metals and has excellent heat resistance and elongation.

び伸びが不充分となる。(M) Modified polypropylene The raw material resins for the modified polypropylene used in the present invention include propylene (a) 90 to 99% heavy duty polymers and an a-olefin other than propylene having a carbon number of 2 to 1 o (b).
A crystalline random valve plate combination with 10 to 1% monomer is preferred. Among these, ethylene is most suitable as the α-olefin, since it has a high α-olefin melting point and a high viscosity when melted, making it difficult to obtain a smooth coating film. Additionally, a smooth coating film can be obtained by preheating the substrate at a high temperature of 800°C or higher during fluidized dip coating, but the coating film obtained in this way has a high degree of thermal deterioration. This results in insufficient strength and elongation.
一部、α−オレフィンの共重合量が１０重九％を超すと
融点が低くなりすぎるので耐熱性および表面硬度が低下
する。If the amount of α-olefin copolymerized exceeds 10% by weight, the melting point becomes too low, resulting in a decrease in heat resistance and surface hardness.

A method of melting and mixing using a famous kneading method such as an extrusion method is difficult. Before melt-mixing, the ingredients of the stiff ingredients are tri-blended in advance using a mixer such as a Henschel mixer, a ribbon blender, or a tumbler, and the mixture is melt-kneaded to form a homogeneous composition. In this case, it is generally melted and mixed, formed into a pellet shape, and then mechanically crushed under freezing conditions at room temperature and used as a powder coating for Meishin painting. be done.
