Compound double-layered glass cement barrel

Abstract

The invention relates to a compound double-layered glass cement barrel. By adopting a technology of compounding a hollowed hard glass cement barrel body and hard and soft glass cement barrels, advantages of the hard and soft glue barrels are integrated and defects thereof are eliminated. As the barrel body is made from an alloy material, a sealing head is made from a plastic, the hard glue barrelis of a threaded connection structure, purposes of optimizing the general performance of the glass cement barrel, lowering the package material and usage costs greatly, reducing the generation amountof glass cement packaging wastes greatly and becoming an energy-saving and environment-friendly 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
