Description
Technical Field
The invention relates to an anti-aging PP hollow plate and a preparation method thereof.
Background
The anti-aging PP hollow plate (polypropylene hollow sheet) is formed by extrusion molding of a polypropylene raw material blended with a polyethylene raw material through a hollow plate production line. The anti-aging PP hollow board is an environment-friendly packaging material, does not generate dust in the use process, has long service life which is more than 4-10 times of the service life of corrugated boards, can be recycled, has the trend of gradually replacing paper corrugated boards, and is mainly embodied on product packaging. In addition, because the anti-aging PP hollow plate is light in weight, good in toughness, flexible in size and relatively low in cost, the anti-aging PP hollow plate turnover box provided with various accessory molding has the potential to replace an injection molding turnover box. However, the toughness and tensile strength of the existing anti-aging PP hollow plate are low, and the service life of the existing anti-aging PP hollow plate is influenced.

table 1 shows the test data of examples and comparative examples
As can be seen from the above table, the addition of the Shanghai raceae HD5210AA-PE can increase toughness and tensile strength, but when the Shanghai raceae HD5210AA-PE is excessive (comparative example 2), its light transmitting property is significantly reduced, and surface cracks are caused and the surface is roughened. In addition, with the addition of the Shanghai raceae C1007-PP compound, the light transmittance of the PP hollow plate is remarkably increased, and when the Shanghai raceae C1007-PP is excessive (comparative example 4), the toughness and tensile strength thereof are remarkably reduced. In addition, the middle petrochemical Qilu K8003-PP material also has a great influence on the surface performance of the material, and along with the increase of the middle petrochemical Qilu K8003-PP material, cracks and surface roughness of the middle petrochemical Qilu K8003-PP material are obviously reduced (comparative examples 5-6).
