Description

High-strength EPS foam box and preparation method thereof

Technical Field

The invention relates to the field of foam box production, in particular to a high-strength EPS foam box and a preparation method thereof.

Background

EPS foam is a light high-molecular polymer, and is a foamed plastic with a hard closed-cell structure formed by adding a foaming agent into polystyrene resin, heating for softening and generating gas. The foam box has the advantages of light weight, small heat conductivity coefficient, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price, high quality and the like, is made into various foam boxes, and is widely applied to the packaging and transportation industry.

However, the EPS foam boxes currently in use suffer from a number of disadvantages: because the restriction of EPS foam self material, the foam case hardness that leads to the preparation to form is lower, and in the transportation, EPS foam case atress causes the box to damage easily, and then damages the product of depositing in the box.

The cross section of the second clamping groove is in an isosceles trapezoid shape, so that the first rib plate and the second rib plate are convenient to mount and convenient to demould during injection molding.

Further, the first rib plate and the second rib plate have the same structure, the first rib plate comprises a rib plate main body and rib plate clamping strips, and the rib plate clamping strips are arranged on four sides of the rib plate main body. The first ribbed plate and the second ribbed plate are fixed with the box body and the box cover through ribbed plate clamping strips.

Furthermore, the rib plate main body is provided with a slot. When being convenient for use, the position accuracy each other has been improved to block between first floor and the second floor to the bulk strength of EPS foam case has been improved.

Furthermore, the cross section of the rib plate clamping strip is arranged in an isosceles trapezoid shape. The rib board clamping strips are clamped in the first clamping grooves and the second clamping grooves on the corresponding box body and the box cover, so that the rib board clamping strips are fixed, are arranged in an isosceles trapezoid shape, are simple and convenient to install and are convenient to demould.

Further, a preparation method of the high-strength EPS foam box comprises the following specific steps:

1) carrying out hot press molding on the box body, the cover body, the first ribbed plate and the second ribbed plate through corresponding dies to obtain a semi-finished product;

2) carrying out corresponding flash treatment on the generated box body, the cover body, the first ribbed plate and the second ribbed plate in sequence, and obtaining a final finished product;

3) selecting a proper number of first rib plates and second rib plates according to the size of a product to be packaged, and sequentially inserting the first rib plates and the second rib plates into corresponding positions in the box body;

4) after the product is placed, the box cover is covered and packaged.

The technical scheme shows that the invention has the following beneficial effects: 1) the strong strips are arranged outside the box body and the box cover, so that the compression resistance of the box body is greatly improved, and the overall strength of the EPS foam box is improved; 2) according to the size of the product to be packaged, the ribbed plates with different numbers are selected and installed in the box body, so that the separating effect is achieved, the damage caused by collision among the products in the transportation process is avoided, the strength of the EPS foam box is greatly improved, and the damage caused by stress is avoided; 3) simple structure, the production of being convenient for is applicable to the packing transportation of different products, has extensive suitability.
