A production process of aluminum profile with 4D wood grain surface

Abstract

The invention relates to a production process of an aluminum profile with a 4D (Four-dimensional) wood grain surface. The production process comprises the following steps of pre-processing the profile; powdering and graining; corroding grains; washing; spraying base powder; carrying out heat transfer printing on the wood grains. The pre-processing of the aluminum profile comprises the following steps of pre-processing and placing the profile; acid pickling; chromizing; drying. The powdering and graining comprises the following steps of graining; powdering through a grain plate to form the wood grains, wherein the speed of a conveyor belt is controlled to be 2.6-2.8m / s; solidifying. The grains corrosion comprises the following steps of placing the profile in alkali bath liquid, corroding the surface part of the profile without the grains, and remaining the part protected by the powder. The washing comprises the following steps of water washing; chromizing; draying. The spraying of base powder comprises the following steps of spraying; solidifying at high temperature. The heat transfer printing of the wood grains comprises the following steps of cutting paper; sticking paper; covering with a high-temperature bag; tidying and vacuumizing; putting the vaccumized profile covered with the plastic bag into a furnace so as to be subjected to wood grain heat transfer printing; cooling and removing the bags. According to the production process of the aluminum profile with the 4D wood grain surface, the concave-convex wood grains are formed, and the wood grain effect is good.

Description

technical field [0001] The invention belongs to the surface treatment production process of aluminum profiles, and in particular relates to a production process of aluminum profiles with a 4D wood grain surface. Background technique [0002] With the development of the economy and the improvement of people's living standards, people have put forward higher requirements for the living environment, such as the laying and decoration of wooden floors, doors and windows. [0003] However, the use of wood-based combustible organic boards is restricted, but the high-quality decoration and beautiful texture of wood-based building materials are still popular. In order to make the building more in line with people's aesthetics, some people now like to use aluminum profiles with log wood grain to make the visual effect more beautiful and luxurious. [0004] However, the surface of the aluminum profiles produced by the existing wood grain production process is flat-finished. The surfac...

Problems solved by technology

[0004] However, the surface of the aluminum profiles produced by the existing wood grain production process is flat-finished. The surface effect of the aluminum profiles produced by the flat wood grain process is often uneven, and it is difficult to achieve an aesthetic decorative effect, and the wood grain effect is poor.
