Low temperature resisting and flame resisting PVC material and preparation and application thereof

Abstract

The invention discloses a low temperature resisting and flame resisting PVC material and a preparation and application thereof. A base and brackets which are horizontally symmetrically and fixedly arranged on the left and right sides of the base are included. A rotating disc is mounted between the brackets on the left and right sides in a rotating-fit mode. A preparation bracket body is fixedly arranged on the bottom end face of the rotating disc. Atmospheric pressure cavities are horizontally symmetrically formed in the preparation bracket body. An ejecting pressing plate is mounted in each atmospheric pressure cavity in a sliding-fit mode. Adjusting brackets are fixedly arranged on the end faces of the opposite sides of the ejecting pressing plates on the left and right sides. The adjusting brackets extend out of the outer side end of the preparation bracket body, and are connected with the preparation bracket body in a sliding-fit mode. Atmospheric pressure holes are formed in the top walls of the atmospheric pressure cavities in a communicating mode. The atmospheric pressure holes on the left and right sides are respectively connected with an atmospheric pressure cylinder. Theatmospheric pressure cylinder is fixedly arranged in the preparation bracket body. First penetrating holes are formed in the adjusting brackets extending the outer side end of the preparation bracketbody in an up and down penetrating mode. Spline shafts are mounted in the first penetrating holes in a clearance-fit mode.

Description

technical field [0001] The invention relates to the technical field of PVC material processing, in particular to a low-temperature resistant flame-retardant PVC material and a preparation method and application thereof. Background technique [0002] At present, when preparing and processing PVC materials, drilling work is required. The current drilling equipment usually only has a single drilling function, so that it is necessary to repeat multiple drilling operations when drilling. The processing efficiency of PVC materials Low, and during processing, when clamping PVC materials, manual adjustment is required, and the operation steps are cumbersome and need to be improved. Contents of the invention [0003] The object of the present invention is to provide a low-temperature-resistant flame-retardant PVC material and its preparation method and application, which are used to overcome the above-mentioned defects in the prior art. [0004] A low-temperature-resistant flame-r...
