Abstract
Description
Technical Field

[0002] EVA transparent heat insulation masterbatch, also known as infrared absorption heat insulation masterbatch, is mainly composed of tungsten, vanadium, tin and antimony oxides. These oxides have a good absorption effect on infrared rays from 780nm to 2500nm. The heat insulation masterbatch is used to form heat insulation films or sheets through injection molding, blow molding or stretching. By absorbing and reflecting infrared rays from the outside, it blocks infrared heat on the surface or reflects it directly into the outside space, thereby providing heat insulation for the covered space while maintaining high light transmittance. Patent document CN215703254U discloses a feeding device for flame retardant masterbatch production, including a base plate. The top of the base plate is fixedly connected to the flame retardant masterbatch production equipment body. The top of the base plate is fixedly connected to a support plate via a bracket. The support plate is located on top of the flame retardant masterbatch production equipment body. The top of the support plate is fixedly connected to a control box. The top of the control box is fixedly connected to a feeding hopper. The control box is connected to the support plate and the feeding hopper. A through groove is opened on the top left side of the inner wall of the control box, and a through groove is opened on the bottom right side of the inner wall of the control box. A storage groove is opened on the rear side of the inner wall of the control box. A control mechanism is set inside the control box, and a transmission mechanism is set on the right side of the control box.
