Problems solved by technology

Solvent-based adhesives not only cause a serious waste of resources, seriously pollute the environment, but also pose a great threat to the health of construction workers
[0005] Moreover, since most of the automotive flocking interior parts are curved surfaces or box-like parts, using ordinary flocking methods, flocking on curved surfaces and box-like parts has defects of uneven flocking or large-area lodging; for exterior parts, flocking Fleece products are prone to defects such as surface shade or uneven color, which affect the appearance of parts

Abstract

The invention discloses a plasma flocking method for automobile interior parts, which includes the following steps of (1) surface polishing; (2) adhesive coating; (3) electrostatic flocking; (4) curing; and (5) cleaning. The plasma flocking method for the automobile interior parts is simple in process, low in cost, high in production efficiency and finished product yield, wide in applicable range and suitable for various materials, realizes flocking on surfaces of the interior parts in different shapes and further can treat complicated structures effectively by means of plasma surface treatment. The flocked products of the automobile interior parts manufactured by the method have standing flocks and have the advantages of excellent wear resistance, adhesion force, desiccation resistance, wet-cleaning resistance, cold resistance, clacking resistance, fine touch and the like. In addition, since the selected adhesive is made of environment-friendly raw materials, no pollution can be caused during use of the method.

Description

technical field [0001] The invention relates to a flocking method, in particular to a plasma flocking method for automobile interior parts. Background technique [0002] Automotive interior parts, the English name Automotive Interior, mainly refers to the automotive products used in the interior modification of the car, involving all aspects of the car interior, such as glove boxes, car seat back panels, car inlay panels, car side panels, and pillar guards , Door panels, car sub-dashboards, glove boxes, radio boxes and central consoles are all automotive interior products. The automotive interior system is an important part of the car body, and the design workload of the interior system accounts for more than 60% of the car styling design workload, far exceeding the car shape, and is one of the most important parts of the car body. [0003] At present, the surface flocking of automotive interior parts is used in the design of automobiles to improve the decorative effect of ...
