Description

DETAILED DESCRIPTION OF THE INVENTION [B] Concerning a steel plate reinforcing material in which two cups of thermosetting resin are added to supplement the rigidity of press-formed products such as steel plates used for wood coating and electrodeposition coating. Yes. For press-formed steel sheets used in automobile bodies, etc., thin tensile steel sheets are used to reduce the weight of car bodies. If a thick steel plate is used, the bending rigidity etc. will be low, so the steel plate will be pushed up with a little pressure.
The so-called jli4 j'n1~ is low -[・do. In order to compensate for the stiffness 1'1 of the steel plate, a steel plate reinforcing material mainly composed of thermosetting resin sheet 1- is adhered to the back side of the press-formed product to ensure the necessary rigidity. however,
After the press-formed product using the steel plate reinforcement material is
It has become clear that when an electrodeposition coating is formed using tt 24, chains may occur at the boundary between the electrodeposition coating and the steel plate reinforcing material.

The present invention provides an electrodeposited article (
1. To provide steel plate reinforcement materials for flexible parts that can be supported.
There is a "C" in the mark.

In order to prevent the above-mentioned rust, invented coins, etc. have a 7Z-RJ connection and a conductive layer 41 (N) on the adhesive layer of the steel plate reinforcement.
J decided to take the initiative, and with the hope that this problem would be solved, we completed a steel plate reinforcing material that does not rust easily.

That is, the steel plate reinforcing material of the present invention is bonded to a steel plate in order to increase the rigidity of the steel plate for improving the densification resistance. (=J 4

Rigidity made of a thermosetting composition containing high-rigidity fibers, mica, etc. There is a C.

The thermosetting adhesive composition constituting the adhesive layer of the present invention (
It has sufficient non-fluidity to fix the magnetic powder at room temperature, and when heated, the viscosity increases by 1 to 1, and the surface tension at It is preferable to use thermosetting 11 resin which accelerates the reaction and hardens the crosslinking reaction.Specific thermosetting resins and crosslinking resins include: The thermosetting adhesive composition includes the thermosetting resin, polyester resin, polybutyral, and polybutadine resin. A curing agent, a crosslinking agent, and a reaction accelerator are blended with these resins. It is a mixture of cross-linked resin, inorganic additives, and fillers.Additives include thickeners such as asfufu-ru 1-based substances, surfactants, powdered rubber, etc. Examples include oil-absorbing agents. Examples include metal powders such as aluminum powder, powders such as clay and calcium carbonate, and powders such as night powders. It is difficult to specify because the composition ratio differs by 1 or 2 from formulation to minute, and the non-flowability at γ temperature changes greatly depending on the resin molecule m. 1.

If the steel plate is thinner than this, the stiffness (C') of the steel plate will be insufficient (strain absorption effect between it and the layer C'); conversely, if it is thicker, the stiffness effect of the layer C' will be reduced.゛Rigidity (=J decoy) is mainly characterized by the fact that it contains high rigidity fibers such as glass ll1i, carbon fibers, metal fibers, rigid and highly oriented fibers, and rigid thin J hair such as mica.

Preferably, the fibers are thick and long. However, from step 1!1, short fibers such as glass chops may be used. Also, it is preferable that the thin part be wide. Rigidity 1 "1 Highly oriented fibers are straight" -

G, L, glass powder, clay, aluminum powder, etc. can be used as the R shrine. The blending ratio of the inorganic filler is 5 to 80%, preferably 30 to 60%.

The thickness of the rigid layer is preferably 1 to 3 mm. The thicker the layer, the more the thickness of the stiffening layer increases. In addition, it has rigidity! The -j layer also has a feature of the present invention, in which conductive powder or conductive powder and magnetic powder are blended! (Moni.

Incidentally, it is preferable to use a sheet-shaped or j-shaped fiber combination among the fibers. In such a case, a rigid layer can be formed by filling and coating a thermosetting resin composition into the gap between the fiber eaves 1 formed by t1. , many Il?

As conductive powder, metal powder, carbon powder, etc. are used.As metal powder, silver powder and copper powder are used. The carbon powder is known as Niu Kasumi IJU Carbon.
Carbon with 19 moons is preferable since it has the body of Chengdui h's hard right resistance. In addition, with such carbon fibers made by Kodenjin,

By using 7EC for a period of time, an adhesive layer with high electrical properties can be obtained with a relatively small amount. Incidentally, by mixing carbon powder and aluminum (carbon powder), a contact 6Fi with excellent conductivity can be obtained.

In this case, the appropriate blending ratio of the M conductive powder is 1 to 30% by weight. In addition, when mixing metal powder such as aluminum powder with carbon powder as conductive powder, the metal powder is 1,000 m% r1 = 20%, and the 7J-bon powder is 1 to 10 m% by weight. The degree is appropriate.
