Abstract
Description
Technical Field
[0001] The utility model relates to the field of masterbatch drying equipment, and more specifically to a masterbatch drying device for PE foaming plates. Background Art
[0002] Polyethylene (PE) has excellent physical, chemical and mechanical properties. It has good toughness, flexibility and cushioning properties. It has electrical insulation and heat insulation properties and is widely used in packaging, chemical industry and construction. PE foam material is one of the earliest industrially applied and widely used foam materials. The varieties and application fields of PE foam materials are diversified. According to the foaming ratio, it can be divided into high foaming, low foaming and microporous foam materials; according to the shape, it can be divided into beads, sheets and profiles; according to the pore morphology, it can be divided into closed-cell and open-cell foam materials. At present, the output of PE foam material is second only to polyurethane (PU) and polystyrene (PS), but it is more widely used than PU and PS. More than 1000 kinds of products have been developed, and it is developing rapidly.
[0003] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an extraordinary amount of pigment in the resin. It can be called pigment concentrate, so its tinting power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration.
[0004] Based on the above, the inventors found that when the masterbatch is dried, the masterbatch will accumulate inside the cylinder, which is not conducive to drying the masterbatch. This may cause uneven drying of the masterbatch after long-term use and cause a low drying effect. Therefore, in view of this, the existing structure is studied and improved, and a masterbatch drying device for PE foam board is provided, in order to achieve a more practical purpose.
