Embodiment Construction

[0013] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 Shown, a kind of novel weather-resistant plastic surface hot stamping method provided by the present invention comprises:

[0015] Step 101, performing surface pretreatment on the plastic surface by washing with flame, corona or lye;

[0016] Among them, surface pretreatment can improve the adhesion and water resistance of later graphics and text.

[0017] Step 102, performing silk-screen thermoplastic coating on the plastic surface;

[0018] Step 103, using a hot stamping template to perform hot stamping on the plastic surface;

[0019] Step 104, performing constant temperature baking on the hot stamped plastic surface.

[0020] Wherein, step 102 may specifically include:

[0021] Step 102-1, printing...

Abstract

The invention relates to the field of plastic processing, and discloses a novel weather-proof plastic surface hot stamping method. The method is characterized in that surface pretreatment is carried out on the surface of plastic by adopting flame or corona or alkali liquid water washing, silk-screen thermoplastic coating is carried out on the surface of the plastic, a hot stamping template is usedso as to carry out hot stamping on the surface of the plastic, and constant-temperature baking is carried out on the surface of the hot-stamped plastic. According to the novel weather-proof plastic surface hot stamping method, the technology is more environment-friendly, the large-scale production is easy to realize, and sinking due to hot stamping cannot occur to a coating after the coating is subjected to UV curing, so that the weather resistance of hot-stamped images and texts is improved, and the images and texts are kept intact under the outdoor severe environment.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a novel weather-resistant plastic surface hot stamping method. Background technique [0002] Silk screen printing of plastic parts is one of the secondary processing (or reprocessing) of plastic products. The so-called secondary processing is to carry out a surface decorative treatment after the injection molding of the plastic product, such as: plastic electroplating, plastic spraying, plastic hot stamping, plastic silk screen printing, etc. The secondary processing of plastic products is mainly determined by the performance of the plastic itself, such as its dyeability is relatively simple, and the color's light fastness is also poor. In order to make up for these shortcomings and improve the appearance and decoration of plastic products, secondary processing is required. The plastic hot stamping in the prior art has poor weather resistance, and is easily damaged when expose...
