Embodiment 1

[0049] This embodiment is a scratch-resistant and durable PP plastic box material, which is prepared by the following steps:

[0050] S1: Put polypropylene in the container and heat-melt it;

[0051] S2: Add modified wollastonite and durable agent to the hot-melted polypropylene, and stir evenly;

[0052] S3: inject the stirred mixture into the mold, and shape it;

[0053] S4: Open the mold to obtain the anti-scratch and durable PP plastic box material;

[0054] Modified wollastonite is prepared by the following steps:

[0055] S31: Add hydrogen-containing polymethylsiloxane, octamethylcyclotetrasiloxane and hexamethyldisiloxane into a four-necked flask equipped with a serpentine reflux condenser, a mechanical stirrer and a thermometer, and then add Add Amberlyst15 macroporous strongly acidic cation exchange resin to the system, control the rotation speed of the electric mixer to 300r / min, heat to 90°C and then carry out the reaction at a constant temperature. First, filter...

Embodiment 2

[0063] The difference between this embodiment and embodiment 1 is:

Abstract

The invention discloses a scratch-resistant durable PP (polypropylene) plastic box material and a preparation process thereof, and relates to the field of plastic box materials.The scratch-resistant durable PP plastic box material is obtained by placing polypropylene in a container, performing hot melting on the polypropylene, adding modified wollastonite and a durable agent into the hot-melted polypropylene, performing uniform stirring, injecting the mixture into a mold, performing shaping treatment and opening the mold. The problems that an existing PP plastic box material is prone to being scratched, affects the use feeling of products, is prone to aging and breakage and is short in service life are solved. The wollastonite has the advantages of being good in chemical stability, low in water absorption and low in price, inorganic filler is introduced into a PP matrix by adding the modified silica fume, the surface of the modified wollastonite is fully organized, the rigidity and impact strength of the PP matrix are improved, and therefore the scratch resistance of the PP material is improved; transmission and growth of free radical chains of the PP material are terminated, so that the PP material is longer in service life and more stable in performance.

Description

technical field [0001] The invention relates to the field of plastic box materials, in particular to a scratch-resistant and durable PP plastic box material and a preparation process thereof. Background technique [0002] PP plastic box is a kind of packaging box made of PP material. There are smooth PP plastic box, frosted PP plastic box, transparent PP plastic box, and solid white PP plastic box. PP material is the lightest quality. Plastic itself is non-toxic and tasteless, has many varieties, is easy to color, bright in color, easy to shape, and has the advantages of good corrosion resistance, acid and alkali resistance, and oil resistance. However, the existing PP plastic box material is easy to be scratched, affecting Product aesthetics and use experience, and PP materials will cause molecular chains to degrade or Cross-linking makes the performance of PP material gradually deteriorate, harden and brittle, easy to age and break, and greatly reduce the service life of ...
