燥炉内を通過させることによって行われる。(2) Prior Art Conventionally, heat-adhesive vibration damping sheets have been used to improve the vibration damping properties of vehicle bodies. The work of attaching this vibration damping sheet is as follows:
This is done by placing the sheet at the required location on the car body and then passing the car body through a drying oven.
（３）発明が解決しようとする課題

な部分には制振シートを貼着することができない。(3) Problems to be Solved by the Invention However, with the above-mentioned vibration damping sheet, there is a problem in that anti-vibration measures cannot be taken in areas where it cannot be placed.For example, on the rear floor of a car body, Even if damping sheets can be attached to approximately horizontal areas such as the front floor and areas with a gentle slope, it is not possible to apply damping sheets to approximately vertical areas such as wheel houses that have the effect of reducing road noise or areas with a steep slope. It is not possible to attach a damping sheet.

ことを特徴とする。B1 Structure of the Invention (1) Means for Solving the Problems The vibration-damping baking-drying paint according to the present invention contains 75 to 3 calcium carbonate per 100 weight of polyester polyol.
00 parts by weight, 0.7 to 2.5 parts by weight of water, and 8 to 30 parts by weight of a high-boiling aromatic solvent, and the blending ratio is 26 to 100 parts by weight to 100 parts by weight of the main component. It is characterized by being composed of diphenylmethane diisocyanate.
（２）作 用

止機能を備えた塗料が調製され、この塗料にまり制振作
用を発揮する耐衝撃性の優れた発泡ポリウレタン系の制
振塗膜が形成される。(2) Function With the above structure, a paint that can be sprayed and has a drip prevention function is prepared, and a foamed polyurethane-based vibration damper with excellent impact resistance that gets stuck in the paint and exhibits a vibration damping effect is prepared. A coating is formed.
各成分の配合理由および配合量限定理由は次の通りであ
る。The reason for blending each component and the reason for limiting the blending amount are as follows.
ポリエステルポリオール、ジフェニルメタンジイソシア
ネート（以下、ＭＤＩと称す）および水は、発泡ポリウ
レタン系制振塗膜を得るための塗膜形成成分である。Polyester polyol, diphenylmethane diisocyanate (hereinafter referred to as MDI) and water are coating film forming components for obtaining a foamed polyurethane damping coating film.
この場合、ＭＤＩの配合量が主成分に対して２６重量部
未満では、重合度が低いため、高強度な制振塗膜を得る
ことができず、一方、１００重合部を上回って配合して
も効果は変らないので経済的に不利となる。In this case, if the amount of MDI blended is less than 26 parts by weight based on the main component, the degree of polymerization will be low, making it impossible to obtain a high-strength vibration damping coating; However, since the effect remains the same, it is economically disadvantageous.
水は、ＭＤＩと反応して炭酸ガスを発生し、この炭酸ガ
スにまり制振塗膜を発泡させることができる。たりし、
水の配合量が０．７重量部未満では発泡が不十分であり
、一方、２．５重量部を上回ると、発泡が過度に進行し
て制御！！！膜が脆くなる。The water reacts with the MDI to generate carbon dioxide gas, which is trapped in the carbon dioxide gas and can cause the damping coating film to foam. Tarishi,
If the amount of water is less than 0.7 parts by weight, foaming will be insufficient, while if it exceeds 2.5 parts by weight, foaming will proceed excessively and control! ! ! The membrane becomes brittle.
炭酸カルシウムは、塗料の垂れを防止し、また制＊塗膜
の耐衝撃性を向上させる効果を有する。Calcium carbonate has the effect of preventing paint from dripping and improving the impact resistance of the control coating.
た＼゛し、炭酸カルシウムの配合量が７５重量部未満で
は、前記効果を得ることができず、一方、３００重量部
を上回ると、制振塗膜が脆くなる。However, if the amount of calcium carbonate is less than 75 parts by weight, the above effects cannot be obtained, while if it exceeds 300 parts by weight, the damping coating film becomes brittle.
高沸点芳香族系溶剤は、塗料の塗布性および塗着性をａ
ｉｉｉｉｒｙするために用いられる。たりし、前記溶剤
の配合量が８重量部未満ではスプレー塗布性が悪化し、
一方、３０重置部を上回ると、垂れが発生する。High-boiling aromatic solvents improve the coating and adhesion properties of paints.
Used to iiiry. However, if the amount of the solvent is less than 8 parts by weight, spray applicability deteriorates,
On the other hand, if it exceeds 30 overlapping parts, sagging occurs.
また高沸点芳香族系溶剤としては、ジエチルベンゼン、

Isopropylbenzene, triamylbenzene, tetraamylbenzene, didodecylbenzene, alcoholic toluene,
p-cymene, tetralin, decalin, dipentene, p-
Menthane etc. are used.
制振塗膜の焼付乾燥温度は１２０〜１８０℃が適当であ
る。その温度が１８０℃を上回ると、制ｆｉ塗膜が脆く
なり、一方、温度が１２０℃未満であると、発泡が不十
分になる。The baking drying temperature of the damping coating film is suitably 120 to 180°C. When the temperature exceeds 180°C, the anti-fi coating becomes brittle, while when the temperature is below 120°C, foaming becomes insufficient.
（３）実施例

The high proportion of calcium carbonate prevents the paint from dripping, but on the other hand, the high proportion of water causes excessive foaming, and as is clear from the coating table. In formulation example-2,
Since the blending ratio of calcium carbonate is low, the ability to prevent the paint from dripping is poor, and this is clearly evident in the upward spray method. Moreover, the appearance of the coating film is also deteriorated due to the dripping of the coating material.
