Composite double-layer rubber barrel

Abstract

The invention relates to a composite double-layer rubber barrel. According to the composite double-layer rubber barrel, a hollow-out hard rubber barrel body is adopted, a hard rubber barrel and soft rubber barrel composite technology is adopted, advantages of a hard rubber barrel and advantages of a soft rubber barrel are integrated, defects of the hard rubber barrel and defects of the soft rubberbarrel are overcome, a barrel body is made of an alloy material, a seal head is made of plastic, and the hard rubber barrel adopts a flip type rotating buckle and clamping buckle combined connectionstructure, so that the purposes of optimizing the overall performance of the rubber barrel, reducing material and use cost greatly, reducing the production amount of glass cement packaging waste greatly, and becoming a energy-saving, environment-friendly and resource-saving type product are achieved.

Description

technical field [0001] The invention relates to a composite double-layer rubber cartridge, in particular to a composite double-layer rubber cartridge which adopts the hollowed-out cylinder body and the organic combination technology of hard and soft double cylinders. Background technique [0002] Glass glue is a material that bonds and seals various glasses with other substrates. It is mainly divided into two categories: silicone glue and polyurethane glue. Silicone sealant is what we usually call glass glue, and it is divided into two types: acidic and neutral; neutral silicone sealant is divided into stone sealant, mildew-proof sealant, fireproof sealant, etc. [0003] As a typical environment-friendly polymer material, glass glue products have the advantages of other products in terms of high temperature and low temperature resistance, electrical insulation, ultraviolet resistance, weather resistance, water resistance, flame retardancy, corrosion resistance, physiological...

Problems solved by technology

[0005] The existing structural adhesives packaged in soft rubber tubes in the market are mainly used as high-end varieties of glass glue through special large-scale extrusion guns containing rubber tubes because of their good sealing performance and the product is not easy to deteriorate. It is convenient and must be equipped with a special extrusion gun, so glass glue other than structural glue is packed in hard plastic cartridges

[0006] Extrusion guns that are widely used are generally used to extrude silicone sealant in hard rubber tubes. The shells are hard plastic tubes or paper tubes, which can only be used once. The number of hard shell packages of glass glue discarded every year has exceeded More than one million tons, resulting in a great waste of resources and environmental pollution

The advantage of the hard plastic tube is that it is easy to use; the disadvantage is that the sealing performance is high, and the bottom cover needs to have a breathing function to adapt to the change of the ambient temperature, so the manufacturing and processing materials and precision requirements are extremely high; the bottom cover can only move in one direction. Therefore, it can only be used as a one-time product; due to factors such as temperature and deformation, the bottom cover is prone to air leakage, which can easily lead to deterioration of the glass glue; it consumes a lot of materials, and compared with the same filling volume of the rubber cartridge, the soft rubber cartridge It saves 70% of materials compared with plastic plastic tubes, and the material cost of plastic hard plastic tubes is higher; the waste of plastic hard plastic tubes is non-degradable in the environment, which pollutes and harms the natural environment greatly; the sorting and collection of hard plastic tubes , it needs to consume a lot of manpower, material resources, financial resources and transportation resources; the processing of hard plastic tubes needs to consume a lot of resources and produce substances harmful to human body and environment
