Special pipe lubricant for concrete pumping equipment, and preparation method thereof

Abstract

The invention discloses a special pipe lubricant for concrete pumping equipment, wherein the special pipe lubricant comprises the following raw materials by weight: 40-50% of polyacrylamide, 45-55% ofsodium silicate, and 3-8% of sodium hydroxide. The preparation method comprises: mixing polyacrylamide and sodium silicate according to a certain ratio, adding sodium hydroxide, and completely stirring and uniformly mixing to prepare the special pipe lubricant for concrete pumping equipment. According to the present invention, the special pipe lubricant can reduce the pipeline friction and the pipeline resistance, greatly improve the concrete pumping capacity and the conveying efficiency, reduce the wear on the inner wall of the pump pipe, and improve the service life of the pump pipe, is convenient and quick to use, and further can save the time and reduce the labor intensity of the operator.

Description

technical field [0001] The invention relates to the technical field of building concrete lubricants, more specifically to the technical field of concrete pumping pipe moistening agents. Background technique [0002] Concrete lubricant is a lubricant used to lubricate the pump pipe of the pump truck before the ready-mixed concrete is pumped. Before the concrete is pumped, the pump pipe of the pump truck must be wetted and lubricated by the lubricant Otherwise, the concrete will cause serious wear to the inner wall of the pump pipe during the pumping process, and it is easy to block the pump. In the past few decades, the ready-mixed concrete industry all over the country has been using mortar to moisten the pump pipes of concrete delivery pumps. However, the use of mortar as a pipe moistening agent has the following shortcomings: First, the effect of moistening the pipes is not very ideal, and the lubrication The performance is poor. When the concrete is pumped, the friction ...

In the past few decades, the ready-mixed concrete industry all over the country has been using mortar to moisten the pump pipes of concrete delivery pumps. However, the use of mortar as a pipe moistening agent has the following shortcomings: First, the effect of moistening the pipes is not very ideal, and the lubrication The performance is poor. When the concrete is pumped, the friction resistance through the pipeline is large, which reduces the concrete delivery efficiency. Moreover, the surface tension, viscosity and adhesion of the mortar are poor, and a uniform and stable lubricating protective layer cannot be formed on the inner wall of the pump pipe, which seriously It affects the lubrication performance and shortens the service life of the pump pipe; secondly, the mortar needs to consume a large amount of ingredients such as cement, lime paste and clay, and the production cost is high, and the mortar is used as a moisturizing agent in a large amount within the length of the pump pipe , resulting in a large waste, and because the pipe lubricant is usually discarded directly after use, it causes a large pollution to the environment and is not very environmentally friendly; the third is that the mortar needs to be stirred and mixed by a special person before use, which not only takes a long time , a waste of time, and the labor intensity of the operators is high, which increases the labor cost
