Preparation method of foam joint sealant

Abstract

The invention relates to a preparation method of a foam joint sealant, which uses a foam joint sealant preparation device, the foam joint sealant preparation device comprises a batching mechanism anda stirring and filling mechanism, the lower end of the batching mechanism is connected with the existing working ground, and the stirring and filling mechanism is arranged below the middle part of thebatching mechanism. And the stirring and filling mechanism is arranged at upper end of existing working ground. According to the invention, the design concept of an independent proportioning and mixing stirring phase structure is adopted to prepare the foam joint sealant, and the arranged batching mechanism adopts a multi-station design, so that independent and accurate proportioning of differentraw materials can be realized; the stirring and filling mechanism can form a relatively closed state in the mixing and stirring process of the raw materials, so that the probability of splashing outwards during mixing of the raw materials is reduced; meanwhile, a movable connecting structure is mostly adopted in the stirring and filling mechanism so as to facilitate regular disassembly and cleaning.

Description

technical field [0001] The invention relates to the technical field of preparation of foam sealant, in particular to a preparation method of foam sealant. Background technique [0002] Foam sealant is a kind of vulcanized rubber, also known as sponge vulcanized rubber. Its characteristic is not to corrode the foam solid model but the rubber material of honeycomb porous material. It can be divided into perforated, omentum capsule, mixed hole and microporous plate. Made of soft vulcanized rubber or hard rubber and plastic products, the foam gap filler has excellent characteristics such as light weight, softness, ductility, and not easy to conduct heat, and has the functions of shock resistance, impact relief, heat insulation, and sound insulation. It is suitable for various Self-adhesion of various soft plastic raw materials and mutual adhesion with hard raw materials, such as foam, sponge, etc. and hard tinplate, aluminum alloy plates, floor tiles, etc. The following problem...

Problems solved by technology

[0003] 1. The method of using the same tool to mix raw materials and then use the stirring structure to mix is ​​likely to cause errors in the proportioning ratio, and the proportioning tool is in an unclean state after use. At the same time, the stirring process of the raw materials is relatively simple, so that the time required for full mixing Longer, lower overall efficiency;

[0004] 2. During the mixing and agitation of the raw materials and the unloading of the mixed raw materials, the end surface in contact with the raw materials is easy to adhere to the raw materials, and the adhered raw materials are easy to form an adhesive scab layer if they cannot be effectively removed. At the same time, the stirring structure and Most of the proportioning structure adopts fixed installation method, which is not conducive to the overall cleaning of the two
