Abstract

The invention belongs to the technical field of EPS foaming, and particularly relates to a high-strength composite EPS foam heat preservation box. The heat preservation box is obtained by splicing EPS composite boards, and the EPS composite boards are prepared through a two-step method. The method comprises the steps that (1) a layer of tensile fiber net is flatly laid at the bottom of a forming mold, the mold is filled with an EPS foaming raw material, heating foaming forming is conducted, and a semi-finished plate is obtained; (2) the semi-finished plate is placed in another mold, the face, provided with the tensile fiber net, of the semi-finished plate faces downwards, another layer of tensile fiber net is laid on the semi-finished plate, and the mold is filled with an EPS foaming raw material for form the EPS composite boards. According to the high-strength composite EPS foam heat preservation box provided by the invention, the boards are manufactured through twice foaming, the outer-layer foaming material is high in density, hardness and strength, and the tensile fiber nets integrally wrap the two sides of the outer-layer foaming material, so that good impact resistance is realized; and the inner-layer foaming material is low in density and moderate in hardness and strength, and excellent buffering and energy-absorbing effects are realized.

Description

technical field [0001] The invention belongs to the technical field of EPS foam materials, and in particular relates to a high-strength composite EPS foam insulation box. Background technique [0002] EPS foam has the characteristics of light weight, heat insulation, and sound insulation. It is often used in product packaging for e-commerce, such as outer packaging boxes for wine and fresh products. However, when using EPS materials to make packing boxes, there is a certain contradiction in terms of strength and hardness. In order to ensure that the packaging box has a good cushioning performance, it is necessary to properly control its hardness. However, controlling the hardness will also reduce the strength of the packaging box and affect its service life. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a high-strength composite EPS foam insulation box. [0004] The present invention is realized...
