Butyl tape is a very common and practical material in construction, decoration and various sealing and waterproof scenes. Many people will use it in construction, but their understanding of it is not deep enough, and there are often cases of incorrect selection and poor use. Today, I will talk to you in detail about butyl tape, from its basic characteristics, classification, production technology, precautions for use, and dry goods throughout the process, which is easy to understand and help you thoroughly understand this common sealing material and avoid stepping on the pit in subsequent use. First of all, we have to clarify a basic concept: butyl rubber tape is a kind of sealant tape made of butyl rubber as the main raw material, adding auxiliary materials such as plasticizer and filler, and processed by a specific process. It is different from the ordinary tape we usually use. Its core advantages focus on sealing, waterproof and weatherability, and it has a long service life and is widely used in various scenes, which is the key reason why it can be widely used in various scenes. Let's talk about the core characteristics of butyl tape, which is also the key to distinguish it from other sealing materials. The first characteristic is excellent sealability and watertightness. Butyl rubber itself has good airtightness and watertightness. After being processed into adhesive tape, it can closely adhere to all kinds of substrates, whether it is smooth metal, glass or rough concrete or stone, and can form a firm sealing layer, effectively blocking the penetration of water and air, which is the core reason why it is often used in waterproof engineering. The second characteristic is strong weather resistance and wide application range. Butyl rubber belt can withstand large temperature changes, and it will not crack, age or fall off easily whether it is exposed to high temperature or cold. When it is used outdoors, its performance will remain stable even after long-term exposure to wind, rain and sun, and it will not fail quickly. This is more advantageous than many ordinary sealant tapes. Ordinary tapes are easy to harden and become brittle at extreme temperatures and lose sealing effect, while butyl tapes can maintain good bonding and sealing performance for a long time. The third characteristic is stable viscosity and strong adhesion. The viscosity of butyl adhesive tape will not decrease rapidly with the passage of time, and it has a good bonding effect on various substrates. Without additional glue, it can achieve better bonding strength by direct bonding, and it is not easy to fall off and become warped after construction. At the same time, its viscosity is pressure-sensitive, so as long as a certain pressure is applied during construction, the adhesive tape can be closely combined with the base material, and it is convenient to operate. The fourth characteristic is environmental protection, non-toxic and safe to use. In the production process, butyl adhesive tape does not add harmful components and has no peculiar smell, which is suitable for safe use in sealed scenes with high environmental protection requirements and will not cause harm to human health and the environment. The realization of this kind of environmental protection performance is also inseparable from the standardized control of the production process. Rui 'an Jiayuan Machinery Co., Ltd. has been deeply involved in the field of coating for many years and has always followed the development direction of intelligence and environmental protection. Relevant processes can effectively guarantee the environmental protection of butyl tape production process and help to produce high-quality products that meet environmental protection standards. Understand the core characteristics of butyl tape, and then let's talk about its classification. According to different application scenarios and processing technologies, butyl adhesive tapes are mainly divided into two types: butyl waterproof adhesive tapes and butyl anticorrosive adhesive tapes. The core components of these two types of tapes are butyl rubber, but there are differences in the proportion of auxiliary materials and processing technologies, and their application scenarios are also different.

Butyl waterproof sealant tape is the most commonly used type, which is mainly used in various waterproof projects, such as waterproof sealing of building roofs, sealing of gaps between doors and windows, waterproof of pipeline joints, waterproof and leak-proof of external walls, etc. This kind of adhesive tape has outstanding waterproof performance, relatively soft texture and good adhesion, which can adapt to the gaps of different substrates, effectively block rainwater infiltration and prevent water leakage and seepage. According to whether there is tire base or not, butyl waterproof sealant tape can be divided into two types: tire-free and tire-free. The tire-free tape is softer and suitable for irregular gaps. The adhesive tape with tire base has higher strength and is suitable for large-area waterproof sealing. Butyl anti-corrosion sealant tape is mainly used in scenes that need anti-corrosion, such as anti-corrosion sealing of metal pipelines and steel structures, anti-corrosion of underground pipelines and sealing of chemical equipment. On the basis of butyl rubber, this kind of adhesive tape is added with anticorrosive components, which not only has good sealing performance, but also can effectively isolate air and moisture, prevent metal substrate from rusting and corrosion, and prolong the service life of equipment and pipelines. It has strong corrosion resistance, can adapt to harsh environments such as acid, alkali and humidity, and is widely used in industrial scenes.

In addition to these two main categories, there are also some special-purpose butyl adhesive tapes, such as butyl double-sided adhesive tapes, which are sticky on both sides and are mainly used for bonding and sealing two substrates; There is also butyl flame-retardant adhesive tape, which has a certain flame-retardant effect by adding flame-retardant components. It is suitable for sealing electrical equipment and cable interfaces and can effectively prevent fire hazards. These different kinds of butyl rubber belts have different requirements for coating process in the production process. With rich industry experience and mature technology, Ruian Jiayuan Machinery Co., Ltd. can adapt to the production needs of various special butyl rubber belts and provide guarantee for the quality of different products.
