Embodiment Construction
[0021] Although all wood is a porous material, it is easy to think that it is more difficult for dense wood to penetrate into iodine and rosin. Longer, the difficulty mentioned here can also be understood as: under the same conditions, the percentage of rosin infiltrated into dense wood is smaller than that of loose wood. Dense wood is common knowledge. For example, mulberry, apricot, and ash are common dense woods, and there are many loose woods: poplar and pine are common non-dense woods.
[0022] The steps are:
[0023] A, take a piece of wood, loose wood is the preferred solution, such as poplar, pine, soaked in the alcohol solution of iodine, soaked until it penetrates 5mm is the preferred solution, then, take out the wood and let the alcohol evaporate, the iodine alcohol solution Also called iodine, it is found through tests that the mass percentage content of iodine in iodine is the preferred solution with 5%-9%, if the concentration is too low, the iodine content in t...

Abstract
The invention relates to a composite material, in particular to lumber permeated by rosin. The preparation method of the composite material comprises the steps of A, soaking the lumber in iodine alcoholic solution, taking out the lumber from the iodine alcoholic solution after the iodine permeates the lumber to be dried until the alcohol is completely volatilized; B, heating rosin in a container so as to melt the rosin into a liquid state, soaking the lumber processed in the step A in the molten rosin, maintaining the temperature at 150 to 180 DEG C for a period of time; C, taking out the lumber, cooling the lumber, and removing the large-particle rosin on the surface of the lumber. The composite material can be used as a liner plate in the soldering tin operation, electronic elements needing to be connected can be arranged on the liner plate, and the rosin is molten through the high temperature generated by soldering iron so as to assist the soldering. The composite material has the beneficial effects that a new method for permeating the rosin into the lumber is provided.
Description
[0001] This application is a divisional application of the invention patent with the application number 2012100692906, the name of the invention: a manufacturing method and application of a composite material: the application date is March 16, 2012. technical field [0002] The present invention relates to a composite material, in particular to a rosin-impregnated wood. Background technique [0003] Electronics hobbyists and electrical repairers solder components with soldering irons, often using rosin as a flux. The very troublesome thing is: hold the soldering iron in one hand, hold the component or circuit board in the other hand, and fix the solder wire at the same time. Because of the limited number of hands, it is very inconvenient to get rosin during the soldering process. Contents of the invention [0004] In order to overcome the shortcomings in the existing soldering process, the invention discloses a composite material, which can be used as a backing plate for s...
