Problems solved by technology

If hot melt adhesive is used, there are problems such as difficulty in coating and deformation of the grating sheet, and its products are not suitable for contact with boiling water, because the melting temperature of general hot melt adhesive is low, and it may be melted and peeled off when exposed to boiling water

Embodiment 1

[0026] Example 1: Injection-molded product with a decorative label on the surface bonded to the microcapsule interface.

[0027] The production steps are as follows:

[0028] 1) Print patterns on the back plane of the lenticular sheet to form a decorative label layer with a three-dimensional effect,

[0029] 2) coating the microcapsule adhesive on the decorative standard material layer,

[0030] 3) Place the decorative standard material coated with microcapsule resin into the cavity of the injection mold, and use static electricity, vacuum or the tension of the sheet itself to position the sheet on the surface of the cavity,

[0031]4) Close the mold, inject the molten plastic into the mould, cool and harden and then open the mold to take out the finished product.

Embodiment 2

[0032] Example 2: A thermoformed article with a decorative label on the surface bonded to the microcapsule interface.

[0033] The production steps are as follows:

[0034] 1) Print patterns on the back plane of the lenticular sheet to form a decorative label layer with a three-dimensional effect,

[0035] 2) Print the microcapsule adhesive after compounding the decorative standard material and the base material,

[0036] 3) After preheating and softening, place it in a thermoforming mold, absorb plastic and attach to the surface of the mold, and form it after cooling.

[0037] 4) Open the mold and take out the finished product.

Embodiment 3

[0038] Example 3: A blow molded product with a decorative label on the surface bonded to the microcapsule interface.

[0039] The production steps are as follows:

[0040] 1) Print the pattern on the decorative standard material,

[0041] 2) Coating the decorative standard material with the base material and then coating the microcapsule adhesive,

[0042] 3) Put it into the blow mold, and adsorb it on the surface of the mold cavity with static electricity or vacuum or static electricity plus vacuum,

[0043] 4) After the length of the parison extruded by the extruder reaches the requirement, close the mold and fill it with compressed gas to form a blow-molded product with a decorative standard.

[0044] 5) Open the mold and take out the finished product.

Abstract

The invention provides a molding product whose surface has decoration label, which comprises a decoration label layer, a molding layer and micro-capsule adhesive agent between said two layers. The producing method comprises following steps: (1) coating or printing micro-capsule adhesive agent on the decoration label layer; (2) putting it into mould to be molded into final product. The invention has the advantages that it can effectively solve the problem in molding process that the decoration label can not adhere incompatible plastic material to make the plastic material which can be used in molding diversified; the solidification agent capsule in the micro-capsule adhesive agent can react solidification intercross reaction with the material of active groups at the instant of breaking or the adhesive agent capsule with active group or hidden active group in carrier resin can react solidification intercross reaction in high-temperature high-pressure molding. Therefore, it can avoid melting the adhesive agent and the detachment of decoration layer when it is used in high temperature.

Description

technical field [0001] The invention relates to a molded product with a decorative label on the surface and a manufacturing method thereof, in particular to a molded product with a stereoscopic image on the surface and a manufacturing method thereof. Background technique [0002] In recent years, the difference between technology and product performance has become smaller and smaller. In addition to the cost performance of products, users have begun to pay more attention to the style and appearance of products. Today's consumers regard the products they use as fashion life tools that express their personality and taste, and choose appropriate products based on three aspects: appearance, brand and functionality. The appearance of a product plays an important role and must be aesthetically pleasing to attract consumers' attention and purchase. [0003] Add bright colors and pleasing or even shiny decorations to products to catch the eye and maintain long-lasting attention, an...
