Description

Foaming noise-reducing sealing adhesive tape and preparation method thereof

Technical Field

The invention relates to the field of noise reduction, in particular to a foaming noise reduction sealing adhesive tape and a preparation method thereof.

Background

The noise reduction is needed in the aspects of life and production. The vehicle class: with the increasing demands for comfort and safety in various vehicles, manufacturers are constantly reducing noise and increasing driving safety in the design and production of vehicles. However, the passenger compartment, the engine and the tires are easy to generate noise and resonance during the running process of the vehicle, and the comfort of the vehicle is affected. When the tire is accidentally punctured by a sharp object in the driving process of an automobile, the tire loses the air pressure in the tire due to the fact that the tire is not specially treated, and dangerous accidents are easily caused for the automobile. The product can reduce the noise and resonance generated by a carriage, an engine and a tire during the running of an automobile, and effectively reduce the sealing leakage and maintain the pressure of the tire when the tire is punctured by a sharp object accidentally.

Household buildings: heat insulation of the foaming material on the roof; the wall body has sound insulation, flame retardance and heat preservation; moisture protection of floors and basements; the house has the advantages of good appearance, energy conservation, environmental protection, aging resistance, convenient construction and the like, and improves the living comfort of the house and the service life of the house.

A medical device: the foaming material and the butyl material have good stability in various natural environments, and the influence of the outside on equipment is reduced. The equipment can be protected in the processes of transportation, storage and use.

Precision instruments: the foaming material has high elasticity, can play a role in resisting vibration to a certain extent, and cannot be influenced by external vibration and resonance. Many precision instruments are affected by vibration during operation. In order to be free from the influence of vibration, customized foaming material application solutions can be provided according to different industries.

Rail transit: the foaming material has the characteristics of better shock-proof buffering, sound insulation, heat insulation, flame retardance and the like, and is mainly used for positions of locomotive-mounted air conditioning ducts, locomotive shock absorption, floors, car bodies, ceilings and the like in the locomotive field.

Aerospace steam material: the aerospace industry has stringent requirements for the weight and volume of the used thermal insulation materials, and often requires that the thermal insulation materials have the properties of sound insulation, vibration reduction, flame retardance, corrosion resistance and the like. The need for insulation varies from aircraft to aircraft. Foamed materials, high silicone foams, are commonly used for thermal insulation in aircraft cabins and cockpit cabins. The heat insulating material for the head of the missile is phenolic foam in the early stage, and with the application of a polyurethane foam material with good temperature resistance, a single heat insulating material is developed into a sandwich structure.

The existing noise reduction product is inconvenient to use, or poor in sound insulation effect and narrow in application range.

(III) advantageous effects

The invention provides a foaming noise-reducing sealing adhesive tape and a preparation method thereof. The method has the following beneficial effects: :

1. according to the invention, the positions of the product to be bonded are cleaned up by cloth or a brush, no oil stain or dust exists, the adhesive tape with a proper size is selected according to the size of the bonded position, the silicone oil paper of the butyl film layer is removed, the butyl film layer is flatly adhered to the surface of the product and is compacted, all the films are ensured to be neatly adhered without overlapping folds, and the operation is simple and convenient.

2. According to the invention, the butyl film is soft and solid jelly, has very stable physical and chemical properties, and cannot corrode a product, and when a sharp object penetrates into or is pulled out of the product, the butyl film can quickly surround the sharp object and timely seal a perforation, so that the integrity is kept.

3. According to the invention, the foaming material layer is a porous material, when sound waves encounter the porous material, vibration is transmitted to the interior of the material, the sound waves rub with complex inner foam holes and are blocked, and energy is attenuated, so that the sound waves are weakened, and therefore, the foaming noise reduction sealing adhesive tape has the advantages of sound absorption and noise reduction.
