Micro-foaming tool kit capable of silk printing and blow molding and preparation method of micro-foaming tool kit

Abstract

The invention relates to a micro-foaming tool kit material and a preparation method thereof and in particular relates to a micro-foaming tool kit capable of silk printing and blow molding and a preparation method of the micro-foaming tool kit. The micro-foaming tool kit comprises the following components in parts by weight: 70-90 parts of polyethylene, 5-15 parts of ultrahigh-flowability polyethylene, 0-10 parts of filler, 1-10 parts of polar modifier, 1-5 parts of compatilizer, 1-15 parts of toughening agent, 1-10 parts of foaming agent, 3-15 parts of foaming auxiliary and 0.5-2 parts of other auxiliaries. In addition, the invention discloses a preparation method of the micro-foaming tool kit. The micro-foaming tool kit disclosed by the invention is fine and smooth in molding foam hole, high in foam hole density, smooth and uniform in surface, capable of uniformly smearing and spreading a paint, abundant in texture, strong in silk printing paint adhesive strength, free of dropping after being proved by adhesion force tests, capable of meeting a silk printing requirement of the tool kit and also capable of meeting silk printing of various types of printing ink and also has the characteristics such as lightweight, good buffering effect, good dimensional stability, short molding period and high finished product qualified rate.

Description

technical field [0001] The invention relates to a toolbox material and a preparation method thereof, in particular to a silk-screen-printable blow-molded microfoaming toolbox and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] The blow molding tool box gathers various tools together for easy use and management and maintenance. On the premise of meeting the basic mechanical performance requirements, it is also required to have a beautiful appearance. Among them, the exquisite appearance is mainly obtained by silk screen printing. Due to its unique sandwich structure, blow molding micro-foaming technology can achieve substantial weight reduction on the premise of meeting the mechanical performance requirements of toolbox products, which can not only significantly reduce product costs, but also improve product portability and product integration. . However, in practical applications, because the foaming proce...

Problems solved by technology

However, in practical applications, because the toolbox foaming process is free foaming, the product surface is not smooth, pitting and other defects, and the toolbox silk screen printing process has very strict surface smoothness requirements

The above defects are easily enlarged during the silk screen printing process, which will seriously affect the silk screen printing effect of product trademarks in the later stage, resulting in unclear fonts, blurred, incomplete, ink dragging, missing printing, misalignment, overlapping, uneven smearing, etc., and even Cause ink to fall off, etc., seriously affecting the appearance quality of the toolbox
