In recent years, butyl rubber material waterproof sealant adhesive tape has been widely used in construction, industry and other industries, mainly used in subway tunnel construction gap sealing waterproof treatment, automobile assembly sealing bonding, heterosexual material bonding waterproofing, waterproof engineering interface waterproofing, ventilation pipe waterproofing, underground waterproofing, residential doors and windows airtight waterproofing, roof waterproofing, ventilation equipment pipe damping shock absorption, household air conditioning pipeline damping, ship pipeline damping damping and other related aspects. Butyl waterproof sealant adhesive tape adopts advanced technology and other additives processing, can ensure that the tape will never cure, has strong adhesion, aging resistance, weather resistance and waterproof, can reduce and protect the vibration and sealing of the adherent surface, does not contain solvent, so does not contain toxic gases, will not shrink, and has a strong follow-up to the mechanical properties of thermal expansion and contraction on the surface of the adhesive. Due to the high price of butyl rubber, waterproof tape made of butyl recycled rubber has obvious advantages in price in recent years, and some enterprises use waterproof tape made of HONGYUN butyl recycled rubber to rapidly expand their market share.
HYE3M7D3 Butyl recycled gum is a new material made from waste materials such as waste butyl tubes or capsules. Compared with butyl rubber, its production process is relatively simple and the cost is lower, so it has been widely used in the production of butyl waterproof tape. The quality of butyl rubber waste is one of the important factors affecting the quality of recycled rubber, so choosing butyl reclaimed rubber with stable quality and low price is the key.
The waterproof tape formula produced by Hongyun butyl reclaimed rubber is as follows: 100 parts of butyl recycled rubber, 150 parts of polyisobutylene, 300 parts of talcum powder, 30 parts of paraffin oil, 35 parts of C5 resin, 3 parts of N550 carbon black, and 8 parts of magnesium oxide.
In the productionprocess of waterproof materials, the commonly used production method is the double-layer extrusion method. This method is mainly divided into several steps: material pretreatment, plasticization, extrusion, cooling and finished product winding.
In the process of making butyl waterproof tape, choosing the right material for pretreatment can well ensure the performance, shape and processing technology of the material. The above materials are mixed with a rubber mixer, and butyl recycled rubber, paraffin oil, talc and N550 carbon black are mixed evenly to make a uniform butyl rubber masterbatch, and the masterbatch material is injected into the kneading machine to knead, and then polyisobutylene, resin, remaining talc, paraffin oil and magnesium oxide are added, and the rubber is filtered and drained after uniform kneading to make butyl rubber waterproof sealant.
1. It is necessary to master temperature, pressure and other factors, adjust the speed and rotation direction of the extruder, and ensure the dimensional stability of the thickness, width, length and other dimensions of the material. The production efficiency of butyl waterproof tape can be greatly improved by adjusting the equipment and good operation.
2. In the extrusion process, in order to ensure the uniformity, fixation and quality stability of butyl waterproof tape, it is necessary to strictly control the extrusion amount and extrusion direction. At the same time, the product needs to be effectively cooled to make its quality and volume more stable.
3. The finished product winding link needs to carry out quality inspection of finished products, and comprehensively manage their packaging, identification, inspection, shipment, etc. In the whole process, it is necessary to strictly follow the standards and quality standards to ensure that the butyl waterproof tape produced meets the qualified quality standards.
The performance of waterproof sealant adhesive tape of butyl rubber material should meet the technical requirements of JC/T942-2004, including production standards, heat resistance, tackibility, peel strength, heat treatment retention rate, alkali treatment retention rate and water immersion treatment retention rate in the composite building materials industry. Through the ROHS test to check whether it meets the environmental standards, the inspection results meet the EU limit value of harmful substances. The production formula and process of butyl waterproof tape is not simple, and requires continuous research and improvement by professional and technical personnel. The application of butyl reclaimed rubber can effectively improve the production efficiency of butyl waterproof tape, reduce production costs, and have the significance of reducing costs, improving efficiency and expanding market share.
