。(Prior art) Conventionally, after the process of joining vehicle parts made of steel plates in vehicles such as automobiles, the painting process is carried out, but it has been pointed out that the joints of vehicle parts are easy to cast. As a means to prevent rust, a sealant made of vinyl chloride plastisol, which is mainly composed of paste-type vinyl chloride resin and blend-type vinyl chloride resin, is applied to the joints of vehicle parts at room temperature. time 3
A method of performing heat curing treatment for around 0 minutes has been adopted. However, since the sealant made of vinyl chloride plastic sol has high fluidity at room temperature, it flows during application of the sealant and it is not possible to obtain the desired film thickness, so a large amount of thixotropic agent such as fat-treated calcium carbonate is used. In addition, adjustments were made to prevent the sealant from flowing, but sealants with low fluidity lose their leveling properties and cannot be applied to the joints of vehicle parts with a uniform thickness from the beginning. It becomes necessary to finish the material to a uniform thickness using a spatula or the like. However, this uniform finishing work is difficult due to the strong thixotropic nature of the sealant, and the finished surface tends to be uneven, resulting in uneven paint finish during the painting process that is carried out after application. Also, the sealant applied during finishing to a uniform thickness may be scraped off with a spatula, and in that case, the sealing effect cannot be expected at the joints of vehicle parts where the sealant has been scraped off, and the There was a problem with rust.

シール性が悪くなるという問題がある。In addition, acrylic ester resin has been used to improve the adhesion of the sealant to the adherend, but since acrylic ester resin is anaerobic, when the film is formed to a thickness of 115 mm or less, it is difficult to absorb oxygen in the air. As a result, the adhesive strength decreases, and furthermore, as the resin itself hardens, the hardness of the sealing material increases rapidly, resulting in hardness, reduced elongation, and poor sealability to adherends.

As a result of various studies, we have added vinyl chloride/vinyl acetate copolymer resin to the conventional sealing material made of vinyl chloride plastic sol, as a result of various studies to ensure good adhesion with the product and a good paint finish in the post-process. We also discovered that it is optimal to add at least one type of modified acrylic resin, isocyanate resin, or polyamide resin instead of acrylic ester resin, and reduce the amount of thixotropic agent. It has been resolved.

It is added to prevent the seal ring material from becoming fluid during heat curing treatment because it hardens at the front and rear ends.If the amount exceeds 10 parts by weight, the viscosity at room temperature increases, and the Adhesion to parts decreases, and if it is less than 5 parts by weight, it tends to soften and flow during heat treatment. When the blend type vinyl chloride resin exceeds 10 parts by weight, the viscosity increases, the leveling property during application decreases, and the finish of the coating on the sealant tends to deteriorate.51!

From an economical point of view, the amount of the three types of resin is 30 to 4.
0 parts by weight is good. When the thixotropic agent exceeds 10 parts by weight, the viscosity tends to increase and the leveling property during application decreases, and when it exceeds 5 parts by weight, it tends to flow easily and the adhesion to vehicle parts tends to decrease. General-purpose plasticizers for plastic materials such as vinyl chloride resin and resin can be used as plasticizers, but considering the viscosity as a sealant, paint finish, and leveling properties during application, 7-talate ester and polyester-based plasticizers are recommended. It is suitable for use in combination with a plasticizer,
Also, the amount added is preferably 20 to 30 parts by weight. In particular, when a polyester plasticizer is used in combination with the sealant, it is optimal because it improves the finished appearance in the painting process and provides clear paint gloss, and the amount of plasticizer is 20
~8-20 out of 30 parts by weight! ! It is expressed as a quantity part. That is, if it exceeds 20 parts by weight, the viscosity tends to increase and the leveling property during coating tends to decrease, and if it is less than 8 parts by weight, the coating finishing effect will not be sufficiently exhibited.
