Problems solved by technology

The natural disadvantages of this method are ① low precision of artificial glue mixing and large human error, which affects product performance; ② artificial glue mixing and stirring are carried out in an open environment, and are not strictly isolated from the air, resulting in curing agent ( The anhydride group in the acid anhydride curing agent) is very easy to absorb moisture in the air and open the ring to fail, thereby affecting product performance

Abstract

The invention discloses a fully-automatic intelligent glue preparation online mixing epoxy insulation core rod injection pultrusion process. The process specifically comprises the following steps of firstly, glass fiber positioning; secondly, intelligent glue preparation; thirdly, online mixing; fourthly, injection; fifthly, solidification; and sixthly, cutting. The utilized two-component epoxy glue injection system is different from other colloid conveying equipment, the whole glue preparation, stirring mixing and glue injection process is fully automatic, no manual operation is needed, clashmixing in a mixer can be realized, the mixing effect of raw materials is guaranteed, it can also be guaranteed that pressure output is stable, metering is accurate, and the quality of a product is guaranteed fundamentally; meanwhile the process has the characteristics that the delivery capacity and the proportion are precise and adjustable, work is stable and reliable, and the process is suitablefor continuous production; and the content of microbubbles in the obtained epoxy insulation core rod product is very few, and the electromechanical properties are good.

Description

technical field [0001] The invention relates to the field of insulating mandrels, in particular to an injection pultrusion process for fully automatic intelligent glue-dispensing online mixed epoxy insulating mandrels. Background technique [0002] At present, there are two kinds of pultrusion processes for epoxy insulating mandrels in China: a, dipping pultrusion process; b, injection pultrusion process. But these two kinds of processes adopt the method of artificial glue mixing and manual stirring (or dynamic stirring with a mixer). The natural disadvantages of this method are ① low precision of artificial glue mixing and large human error, which affects product performance; ② artificial glue mixing and stirring are carried out in an open environment, and are not strictly isolated from the air, resulting in curing agent ( The anhydride group in the acid anhydride curing agent) is very easy to absorb moisture in the air and cause ring opening failure, which in turn affects...
