Abstract
The invention provides coking products using resin-based coating and cementation method, at least one part of two or more parts to be bonded to one another is coated with a resin-based adhesive coating. The coated part and another party of parts are then contactedly assembled and baked to effect bonding of the contacted area(s) between the parts owing to the adhesive force of the coating. The said coating are alkyd resin , phenolic resin, acrylic resin, epoxy resin or polyurethane resin, one of the said parts is made of magnetic material, others are made of non-magnetic, soft-magnetic, or ferromagnetism metal.
Description
The present invention relates to resinous varnish agglutinating goods and adhering method thereof.
In industry and the various goods used of daily life, have some to include two or more parts, wherein at least one parts for decoration or antirustly carried out application and baking, and these parts are bonding and fit together with tackiness agent.For example, Fig. 8 has schematically showed the packaging technology of stepping motor rotor.This rotor 10 comprises one by magneticsubstance, makes ring 12 and one usefulness nonmagnetic material (SUS304, aluminium etc.) as neodymium-iron-boron (Nd-Fe-B) and makes, and is inserted in the axle sleeve 14 in the ring 12.In this case, get rusty easily as the surface of the ring 12 of magneticsubstance, and outward appearance is bad, thus with axle sleeve 14 assemblings before to carry out application and handle.That is, shown in Fig. 8 (1), adopt electrophoretic painting or be sprayed on the surface of ring 12 to be coated with rust protection coating 16, then shown in Fig. 8 (2), in process furnace 18 (electric furnace, gas furnace etc.), toast, after this shown in Fig. 8 (3), be coated with suitable tackiness agent 20 at the inner edge that encircles 12.Then axle sleeve 14 is inserted in the ring 12, thereby with parts 12,14 bonding fitting together.
Fig. 9 (1) shows that fan-shaped magnet 24 is bonded on the internal surface of the garden tubular yoke 22 in the motor housing with the interval of regulation along garden Zhou Fangxiang.In the case, impose rust proof paint 16 by methods such as electrophoretic paintings on the surface of every fan-shaped magnet 24, handle by in process furnace, curing then, to be coated in the tackiness agent on the baked coating it is bonded on the internal surface of yoke 22 at last.
As mentioned above, industrial or civilian, comprise two or more parts and one of them parts scribbles coating, in the product that after this these adhering components fitted together, need an independent operation so as after to finish application adhesive stripe-coating.As a result, increase owing to operation and adopted tackiness agent that manufacturing cost is risen.In addition, this binding agent overflows from the goods as adhering object, impairs the cooperation of size or causes bad order.Also have, volatile solvent contained in this tackiness agent can evaporate, and pollutes Working environment.In addition, also have a shortcoming: after needing the single parts of application by electrophoretic painting or spray treatment, when baking, because heat affecting causes this part distortion or generation strain, thus the required tolerance range of the product after can not guaranteeing to assemble.
The present invention relates to various industrial and civilian products, described product comprises two or more parts, wherein at least one parts is handled through application, and these parts at this after bonding and fit together, the purpose of this invention is to provide method as described below: (1) does not need to be coated with the operation of binding agent and does not use binding agent, thereby helps to reduce production costs; (2) solve owing to tackiness agent overflows the bad order that causes and improves Working environment; (3) eliminate the distortion or the strain of parts, thereby guarantee the precision of assembling.
For addressing the above problem and finish desired purpose, the adhesive product of employing cold coating of the present invention is characterised in that: the cold coating by having adhesion characteristic is with the parts bonding more than 2, then to this cold coating baking processing, thereby with the above-mentioned parts bonding more than 2 together.
Also have, for addressing the above problem and finish the purpose of being expected, the feature of the adhering method of the employing cold coating of another invention of the application is, the cold coating that will have a bond properties is coated in two or more parts of desiring to bond together at least one, with the parts of described coating and other parts to contact with each other, fit together, baking then is so that the contact site between described parts bonds together because of the cohesive force of this coating.
