Description

 {Multi-hard sealing tape for sealing work}

The present invention relates to a tape for shilling work, and more particularly, to a tape for shilling work, in which silicon, a sealant, a rubber material, and the like are applied to a joint portion of a panel or a joint portion or a weld portion of a metal surface exposed to an automobile body, And more particularly, to a multi-hardness sealing tape for use in a sealant sealing work for enhancing a soundproofing, waterproofing, vibration prevention and adhesion function by using a sealing tape made of a sealing material.

A joining portion or a step portion joining the panel and the panel and a hood and a door hemming portion for preventing water and dust from entering the vehicle body from automobile manufacturing and a sealing agent for joining the body panel joining portion and the vehicle body, I have applied it.

Such a work may be carried out by connecting the inner and outer panels by welding or welding or by using a tube nozzle in which a sealant or the like is accommodated in a fine space generated in a joint portion such as a vertical portion where a plane perpendicular to the plane of the connection portion intersects, And sealing the sealed joints to provide sealing, soundproofing, waterproofing, vibration prevention, and other functions.

For example, when applying a sealing agent using a sealing agent extruded from a nozzle by an industrial robot in an automobile manufacturing process, the sealing agent can be controlled at a density in consideration of the amount of the sealing agent and the moving distance of the nozzle, Can be applied to the vehicle body with a constant cross-sectional shape, thickness and width.

However, in a repair process at an automobile center or a maintenance shop, a sealing operation is performed by a manual operation of an operator without being carried out by an automated robot.

That is, when the parts of the vehicle body panel are deformed, disconnected or accidentally replaced due to an impact caused by an accident at the time of an accident due to a vehicle accident, the appearance of the joint part of the replacement part can not be restored to the initial sealing state by the above- It is necessary for the operator to repair the deformed joint.

At this time, in the repair and coating of the vehicle body, after repairing the junction portion of the vehicle body panel in its original shape, the tube nozzle filled with sealing agent is manually brought into direct contact with the joining portion by the operator and the nozzle of the tube is manually moved and extruded The sealing agent is applied to the joints in the manner described above.

In this manual work, even though the operator takes all the care in moving the nozzle of the tube along the joint path and extruding the sealing agent out of the tube in a uniform and uniform manner, the amount of sealant applied along the path of the joint is constant And it is very difficult to maintain uniform thickness.

This is because, in most cases, the operator can not accurately follow the path of the joint, which results in a high failure rate at which the final surface of the sealant applied to the joint becomes uneven and the joint of the repaired panel is not the same as the original joint So that many problems such as intellectual or re-implementation from the consumer are generated.

In order to solve such a problem, a prior art invention patent No. 10-0498080, which proposes a sealing tape instead of direct application by an operator, is known. This prior art is to manufacture a sealing tape by an automated process, It is possible to seal the joint of the body panel by an extremely easy bonding work, and the sealed joint is advantageous in that the finish is excellent.

Such a sealing tape can also be seen in Japanese Utility Model Registration No. 3,004,875, which is a relatively thick band-like shape with a stepped surface and is made of elastic and vulcanized rubber material and adhered to the joining step of the metal plate in a sticking manner.

The prior art has a stepped portion in which the first surface and the second surface are different in height from each other so as to achieve a safe bonding even at the stepped portion of the bent portion provided on the outer side or the first metal plate and the end portion of the first metal plate, So as to increase the adhesive effect

However, this prior art is disadvantageous in that the quality of the surface finishing deteriorates due to the disadvantage that it is merely limited to the step portion, the problem of difficulty in the precise occlusion corresponding to the step portion or the problem of occurrence of the groove, It is not possible to effectively achieve rust generation, vibration prevention, and waterproofing effect in a space portion generated due to insufficient adhesion.

In order to overcome the above-mentioned problem, the prior art patent publication No. 10-0498080 discloses a structure in which, when a joint between a pair of metal surfaces or metal plates is deformed, after the shape of the joint is completely repaired, A repair seal tape having a curved surface on a top surface including a rubber base material and a vulcanization accelerator so that the sealing tape can be bent along a curved shape when the sealing tape is adhered to a bent portion.

In this prior art, the upper surface bending shape is merely an insubstantial function, and there is a disadvantage that the bending which is substantially in close contact with the bending surface is not formed, and the soft material of the sealing tape is deformed A double-sided adhesive tape or an adhesive for bonding a sealing tape and a disadvantage that a firm adhesive force can not be obtained.

The applicant of the present application has proposed an improved invention patent application No. 10-2015-107354 in order to solve the above problems.

The above-mentioned invention is a shilling tape formed continuously or continuously by automation or manual operation in a manufacturing factory, and can be cut by a worker in a length to be repaired according to working conditions. It is easy to seal by pressing and pressing part. Precise and stable sealing, and it is possible to demonstrate the effect that can be easily performed without expert knowledge and firm adhesive force. Also, by mass-producing and purchasing only necessary amount, A sealant body that can obtain a planar structure and corrugated surface of the corrugated surface, an uneven surface, a soundproofing and a shock-absorbing effect, and an adhesive material such as a sealant or silicon and a rubber material The adhesion due to the adhesion of the wire and the fabric received in the body Bar has proposed the sealing tape to get sex.

However, this prior art is disadvantageous in that, in the case of the recessed portion where the joint surface of the joint panel is formed with a curved surface or the stepped portion of the overlapping portion bent to maintain rigidity, the sealing tape in the minute space portion by welding, Vibration, rust generation and durability are not completely satisfied because the problems caused by failure to reach the inside of the deep space and the micro space formed by welding are not completely blocked.
