Irradiation crosslinking flame-retardant polyolefin foaming material internal mixing equipment

Abstract

The invention discloses irradiation crosslinking flame-retardant polyolefin foaming material internal mixing equipment which comprises a base and a crosslinking foaming material cooling bin. Sliding wheels are arranged at the bottom of the base, the sliding wheels are fixed to the bottom of the base, hydraulic cylinders are further arranged at the bottom of the base and fixedly connected with thebase, and an air compressor support is arranged at one end of the top of the base. An air compressor is arranged at the top of the air compressor support, a guide pipe is arranged on one side of the air compressor, and an internal mixing bin is arranged on the other side of the air compressor. By arranging the air compressor, the effect of applying pressure into the internal mixing bin is achieved, internal mixing materials are effectively fused, the fusion density of the materials is increased, the toughness of the materials is improved, and the flame-retardant effect of the materials is achieved.

Description

technical field [0001] The invention relates to the technical field of banburying of foamed materials, in particular to equipment for banburying of irradiation crosslinked flame-retardant polyolefin foamed materials. Background technique [0002] Polyolefin plastic is a kind of general-purpose plastic, which mainly includes polyethylene (PE), polypropylene (PP) and advanced olefin polymers such as POE, EVA, and MMA. Polyethylene (PE) is further divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). Polyolefin plastics, that is, polymers of olefins, are the polymer materials with the largest output and the most applications; among them, polyethylene and polypropylene are the most important. Due to the characteristics of abundant raw materials, low price, easy processing and molding, and excellent comprehensive performance, it is the most widely used in real life, and its application in automobiles is becoming more and more important, and there is ...

Problems solved by technology

[0003] Authorized announcement number CN201720549324.X discloses a kind of mixing equipment for PVC film production, including mixing chamber body, upper top bolt, lower top bolt, rotor, hot oil tank, hot oil baffle tube, spiral hot oil pipe and electric Heating components, the lower side of the mixing chamber body is left and right symmetrically provided with mutually connected banburying chambers, and rotors are respectively arranged in the banburying chambers; the temperature in the banburying chamber rises rapidly through the action of the hot oil baffle tube. High, improve the mixing efficiency, greatly reduce the heat production that needs to be worked by the upper bolt, because the two sides of the rotor are provided with sawtooth protrusions, so the dispersion effect of the rotor on the PVC raw material is further improved, and the mixing effect is improved. The PVC material in the rotating state will hit the hot oil baffle tube, so that the PVC material can be fully contacted with the hot oil baffle tube while improving the mixing effect, improving the heat utilization rate, and the heat in the hot oil baffle tube The oil is injected into the spiral hot oil pipe, so the feed pipe is preheated to further save the mixing time, but the equipment has the following problems: First, it does not have the function of cooling. The temperature is high, it is difficult to carry out the next operation, and it is easy to cause burns to the staff and reduce work efficiency. To improve this, a kind of mixing equipment for radiation cross-linked flame-retardant polyolefin foam material is proposed
