Description of the Related Art In the case of automobiles, the thickness of a steel sheet for automobiles currently used is 0.8 mm due to reduction in weight and progress of steel sheet strength. Although the structural strength of the steel sheet is sufficient, the steel sheet part with a certain area or more is easily deformed by external stress, so by attaching a steel sheet reinforcement to the inside that is not visible from the outside, the steel sheet Prevents deformation. These reinforcements are rubber, bituminous,
Fillers and additives are mixed and kneaded with synthetic resin materials such as alkyd resin, epoxy resin, urethane resin, urea resin, etc., mixed and kneaded, processed into the desired size and shape by appropriate processing means, and pressure-sensitive adhesive. It is reinforced by sticking it to the steel plate reinforcement with an agent. However, depending on the shape of the car body,
There are places where the shape of the bag is complicated, and it may be difficult or impossible to apply the sheet-like steel sheet reinforcement in the past, and the attachment of the steel sheet reinforcement to such places has been postponed. Was. In addition, even in places where steel plate reinforcements have been used in the past, lighter reinforcements with a steel plate reinforcement effect are being sought in order to respond to the demand for lighter weight in order to improve vehicle fuel efficiency. It is the current situation. [0004] The object of the present invention is to provide a coating-type composition of a steel sheet reinforcing material, which has conventionally been a sheet-like bonded product, so that reinforcement measures are difficult or impossible. In other words, it is possible to reduce the weight of the reinforcing material itself and contribute to the reduction of the vehicle weight. Means for Solving the Problems In order to solve such problems, the inventors of the present invention have conducted intensive studies, and as a result, have studied various mixing examples for applying a sheet-shaped steel sheet reinforcing material to a coating type.
It has been found that the required performance as a steel plate reinforcing material can be obtained with a specific resin combination. That is, the present invention resides in the following. 2 to 30% by weight of a one-pack block type polyurethane resin using an oxime type compound or a lactam type compound as a blocking agent, 3 to 40% by weight of an epoxy resin,
It is intended to contain 0.5 to 15% by weight of at least one filler selected from a hollow filler and a flake-like filler, and to perform foaming at a foaming ratio of 1.2 to 2 times by including a foaming agent. Characteristic composition for coating type steel sheet reinforcement. As the one-pack block urethane resin used in the present invention, a conventionally known block urethane resin can be used. In other words, polyisocyanate is a prepolymer that has been polymerized in advance by a polymerization reaction,
(Tolylene diisocyanate), MDI (methylene diphenyl diisocyanate), XDI (xylene diisocyanate), HMDI (hexamethylene diisocyanate), H 12 MDI (water-added MDI), IPDI (isophorone diisocyanate) and the like. Oxime-based compounds, lactam-based compounds and the like can be exemplified as blocking agents for blocking the terminal groups. The active hydrogen compound used in the present invention includes hydroxyl-containing polyamines, polyamides, glycols, and the like.
Examples thereof include polyols such as polyether polyol, polyester polyol, and acrylic polyol. These resins can be cut back with a suitable high-boiling aliphatic solvent, aromatic solvent or the like. The epoxy resin used in the present invention includes:
It is not limited to a particular type. A bisphenol A type epoxy resin which is usually used in the fields of paints and adhesives can be suitably used. As the curing agent, it is recommended to use a one-component curing agent rather than a two-component curing agent in view of workability. B-stage resins, microcapsules, latent curing agents and the like can be exemplified. Particularly, latent curing agents such as dicyandiamide, BF 3 complex, dihydrazide, guanidine, imidazole and the like can be suitably used. It is essential to include 2 to 30% by weight of a one-pack block type urethane resin and 3 to 40% by weight of an epoxy resin. The one-pack type urethane resin mainly affects the adhesion to the steel sheet.
If the amount is less than the weight%, there is a possibility that the adhesion to the steel sheet becomes insufficient. Even if the amount exceeds 30 parts by weight, the adhesive force does not change in proportion to the mixing ratio, which is disadvantageous in cost. on the other hand,
Epoxy resin directly affects the reinforcing properties of the steel sheet. That is, if it is less than 3% by weight, a sufficient reinforcing effect on the steel sheet may not be exhibited. Even if it is added in an amount exceeding 40% by weight, the reinforcing effect does not increase in proportion to the mixing ratio, which is disadvantageous in cost. The composition of the present invention must contain a lightweight filler in addition to the above resins. Lightweight fillers include plastic balloons, glass balloons, silica balloons,
Examples include hollow fillers such as shirasu balloons and carbon hollow spheres, and flaky fillers such as mica. The compounding amount of the lightweight filler is preferably 0.5 to 15% by weight. Further, when the steel sheet reinforcing material is heated and fused to the steel sheet by heating, the reinforcing material itself is prevented from shrinking to prevent the steel sheet from warping, and also to contribute to weight reduction. It is recommended to add a foaming agent to the reinforcing material.
It is preferable that the composition applied by compounding the foaming agent foams at a thickness ratio of about 1.2 to 2 times. 1.
Foaming less than twice is insufficient to prevent warpage of the steel sheet and requires a large amount of reinforcing composition to obtain the same reinforcing effect, so that a light weight effect cannot be expected. On the other hand, if the expansion ratio exceeds 2, the reinforcing effect may be reduced. Examples of the foaming agent include organic foaming agents such as diazoaminobenzol, azoisobutylnitrile, benzol sulfohydrazide, azodicarbonamide, PP'-oxybenzol sulfohydrazide, and benzyl monohydrazole, and heat-expandable capsules. It is effective to appropriately use a foaming auxiliary in combination with these organic foaming agents. Examples of the foaming aid include urea and derivatives thereof, and thermosetting resins. The amount of the foaming agent is 0.1.
2 to 3.0% by weight is preferred. In the present invention, other fillers can be added as required. Fillers that can be used in the present invention include pigments such as calcium carbonate, barium sulfate, talc, clay, kaolin, zinc white, titanium oxide, silica, and alumina. Further, various additives can be blended as required. Additives that can be used in the present invention are anti-sagging agents,
Examples include a rheology control agent, a dispersant, an anti-settling agent, a moisture absorbent, a high-boiling solvent for improving coating workability, and an acrylic resin for increasing the steel sheet reinforcing effect. The amount of the additive is preferably 0 to 10% by weight. In order to produce the coated steel sheet reinforcing composition according to the present invention, the above-mentioned various components are dispersed and kneaded by a conventionally known mixing and dispersing machine such as a dissolver, a Banbury mixer, a planetary mixer, an open kneader and a vacuum kneader. It is manufactured by doing. Further, the coating type steel sheet reinforcing composition according to the present invention is applied by an airless spray gun driven by an airless pump or the like, an air spray gun, an electrostatic coating machine or the like. The following examples are provided to provide a more detailed understanding of the present invention. As a matter of course, the present invention is not limited only to the following examples. Example 1 TDI of a lactam block, 10% by weight of a polyurethane resin containing a reaction equivalent of a polyester polyol, 30% by weight of a bisphenol A type epoxy resin and a dicyandiamide latent type curing agent, 1.0% by weight of azodicarbonamide, Glass balloon 10% by weight, calcium carbonate 40% by weight, high boiling point solvent 5% by weight, dispersant 2% by weight
Was dispersed and mixed by a planetary mixer to obtain a coating type steel sheet reinforcing composition 1. Example 2 IPDI of oxime block, 6% by weight of polyurethane resin containing a reaction equivalent of polyether polyol, 34% by weight of bisphenol A type epoxy resin and dicyandiamide latent type curing agent, 1.0% by weight of azodicarbonamide , Glass balloon 10% by weight, calcium carbonate 40% by weight, high boiling point solvent 5% by weight, dispersant 2% by weight
Was dispersed and mixed with a planetary mixer to obtain a coating type steel sheet reinforcing composition 2. Example 3 Polyurethane resin 6 containing a reaction equivalent of H 12 MDI of lactam block and polyether polyol
Weight%, bisphenol A type epoxy resin and dicyandiamide latent curing agent 34% by weight, azodicarbonamide 1.0% by weight, glass balloon 15% by weight, calcium carbonate 35% by weight, high boiling solvent 5% by weight, dispersant 2% by weight % Was dispersed and mixed with a planetary mixer to obtain a coating type steel sheet reinforcing composition 3. COMPARATIVE EXAMPLE One side of a heat-fusible steel plate reinforcement material containing a synthetic rubber (styrene-butadiene-based) and an inorganic filler as a main component is subjected to adhesive processing on one surface and a release paper is attached to form a sheet-like steel plate reinforcement material. 4 was obtained. [Test Method] (1) The application type steel sheet reinforcing compositions 1 to 3 are applied to a 25 × 150 × 0.8 mm automobile steel sheet by an airless spray coating machine, and the steel sheet reinforcing material 4 is applied to the same steel sheet. Affix and heat at 160 ° C for 30 minutes with a forced air dryer,
It was heat-sealed to a steel sheet and foamed. The coating type steel sheet composition foamed to an average of 1.5 times the film thickness. (2) Measure the weight of each test piece per 1 m 2 and measure the reinforcing property with a tester capable of measuring and evaluating the reinforcing property. The tester is generally called a tensile tester and can measure, and can control the movement of the crosshead at a constant speed. The test piece was placed on a three-point bending type jig having a span of 100 mm and a compression speed of 1 mm / m.
The test piece is compressed in, the load when the test piece is deformed by 1 mm is measured, and the load is multiplied by the gravitational acceleration to make the test piece reinforcing. [Results] Since the steel sheet reinforcing composition according to the present invention is of a coating type, it can be applied to places where the pasting work has been difficult or impossible because of past application by hand. It can be painted and constructed by devising a painting nozzle. The adhesion to the steel sheet is extremely high due to the high adhesion of the one-pack block type urethane resin, and the adhesion is good regardless of the oil-coated steel sheet subjected to the rust-proofing treatment and the steel sheet with the electrodeposition coating surface. In addition, since the specific gravity is significantly smaller than that of the conventional reinforcing material due to the blending of the lightweight filler and the heat foaming, it is possible to contribute to weight reduction. In the case where the reinforcing composition is foamed by adding a foaming agent, it is possible to prevent the steel sheet from being warped which may occur when a steel sheet reinforcing material is conventionally applied.
