1. The car door water-retaining film adhesive tape improved by using butyl rubber and resin is characterized by being prepared from the following components in parts by mass: 15-25 parts of butyl rubber, 15-35 parts of polyisobutylene, 10-15 parts of resin, 10-30 parts of calcium carbonate, 10-20 parts of talcum powder, 1-5 parts of bentonite and 5-15 parts of white oil.

Technical Field

The invention relates to a car door water-retaining film adhesive tape improved by butyl rubber and resin, and belongs to the technical field of car door water-retaining films.

Background

The car door water-retaining film adhesive tape is formed by mixing butyl rubber serving as a main material with other auxiliary materials and then extruding the mixture, and is used for adhering a water-retaining film to a car door metal plate. At present, the phenomenon that the water-retaining film adhesive tape of the car door falls off from a metal plate easily occurs in the using process. At present, by adjusting the formula of the water-retaining film adhesive tape for the vehicle door, high-Mooney butyl rubber and high-performance resin are used, the Mooney viscosity of the high-Mooney butyl rubber is 46-56, the high-Mooney butyl rubber has high cohesive force, and the peeling strength and the bonding strength required by the water-retaining film adhesive tape for the vehicle door can be well met; however, the requirement that only the peeling strength and the bonding strength are met is not enough, and the bonding effect between the adhesive tape and the metal plate needs to be ensured, so that the high-performance C5 resin is also used in the formula of the adhesive tape, the bonding effect between the adhesive tape and the metal plate can be well increased, and the phenomenon that the adhesive tape and the metal plate are not good in viscosity and fall off when a vehicle is loaded is prevented.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the utility model provides a car door manger plate membrane sticky tape with butyl rubber and resin improvement, it has solved present car door manger plate membrane sticky tape in the use, the easy problem that appears the phenomenon that drops from the panel beating.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

a car door water-retaining film adhesive tape improved by butyl rubber and resin is prepared from the following components in parts by mass: 15-25 parts of butyl rubber, 15-35 parts of polyisobutylene, 10-15 parts of resin, 10-30 parts of calcium carbonate, 10-20 parts of talcum powder, 1-5 parts of bentonite and 5-15 parts of white oil.

The preparation and use method comprises the following steps: according to the proportion, the components are mixed and stirred uniformly, and the prepared adhesive tape is used for adhering the car door water-retaining film to a metal plate.

The invention has the beneficial effects that: the high-Mooney butyl rubber and the high-performance resin are used, so that the bonding strength and the peeling strength of the car door water-retaining film adhesive tape are greatly increased, the bonding effect between the adhesive tape and a metal plate is improved, and compared with the original car door water-retaining film adhesive tape, the phenomenon of falling off cannot occur after the car door water-retaining film adhesive tape is bonded with the metal plate.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

A car door water-retaining film adhesive tape improved by butyl rubber and resin is prepared from the following components in parts by mass: 15-25 parts of butyl rubber, 15-35 parts of polyisobutylene, 10-15 parts of resin, 10-30 parts of calcium carbonate, 10-20 parts of talcum powder, 1-5 parts of bentonite and 5-15 parts of white oil.
