Problems solved by technology

However, there are still some problems in the use of this type of pipeline for mortar transportation
First of all, the wear resistance of rubber materials is poor, and generally the mortar will fail when transporting no more than 500 cubic meters, resulting in frequent replacement of conveying pipes during the spraying process, which wastes a lot of manpower
Moreover, worn rubber delivery pipes cannot be recycled and recycled, which is not environmentally friendly.
In addition, because the vulcanization process must be used in the production process of the rubber delivery pipe, the rubber hose can only be prepared as a fixed-length pipeline. For special occasions (such as the transportation distance is too long), the connection method must be used, which is inconvenient to use

Description

technical field [0001] The invention belongs to the technical field of conveying pipes, is applicable to the field of mortar and concrete conveying, and specifically relates to a modified elastomer, a thermoplastic mortar / concrete conveying pipe and a preparation method thereof. Background technique [0002] Mortar and concrete are widely used bonding substances in construction. They are composed of a certain proportion of sand, stones and cementing materials (cement, lime paste, clay, etc.) and water, also called mortar. Its mixing, conveying and use are essential work on various construction sites. [0003] The delivery of mortar / concrete is carried out by mortar pump and mortar / concrete delivery pipe. For the mortar / concrete delivery pipe, there are usually the following technical requirements: (1) Due to the different working conditions on the construction site, the mortar / concrete delivery pipe is required to be able to bend, and the diameter change of the pipe at the ...
