Definitions
- the invention relates to a method for applying a Anti-drumming compound based on epoxy resins on a vehicle body, in which the applied anti-drumming compound together with layers of paint applied in a paint shop cures in paint ovens, the paint shop a bodyshell oven for curing glue on the bodyshell and a washer to remove dirt, drawing oils in particular, upstream on the bodyshell is. Furthermore, an anti-droning mass is said to Implementation of this procedure will be created.
- Anti-drumming compounds based on epoxy resins require Curing temperatures of over 160 ° C and residence times of at least 20 to 30 minutes. These conditions are in the paint ovens during vehicle production Paint shop fulfilled. That's why you have the anti-droning mass so far immediately before painting on the body applied so that it is in the paint oven together with the paint can harden. However, there is a desire to Paint shop of all not required for painting Keep operations clear, so no contamination can get onto the body after painting to disturb. That is why the desire arose, the anti-drumming mass already applied to the body shell. It However, it was found that this was the case during pretreatment cannot withstand prevailing conditions.
- the problem underlying the invention is a method for applying an anti-drumming compound based on epoxy resins to develop a vehicle body which can be carried out outside the paint shop and too the smallest possible increase in manufacturing costs leads. Furthermore, an anti-droning compound is to be carried out of this procedure.
- this problem is solved in that added a gelling agent to the anti-drumming compound and that Anti-drumming compound containing gelling agent before insertion the body shell is applied in the body shell becomes.
- the anti-drumming compound is applied to the still oiled metal sheets of the bodyshell, so that it can actually be expected that it will at least partially be washed off again in the subsequent washing process in order to remove the oil.
- the gelling agent causes gelling to occur to such an extent that the anti-drumming compound can withstand the conditions when it passes the bodyshell through the bodyshell oven at the temperature of about 120 ° C and the residence time of 10 - 12 minutes required there anyway that prevail in the pre-treatment prior to the painting process.
- Gelling is a physical process, one Swelling "and not yet about the chemical crosslinking process occurring in the paint oven.
- the gelling agent itself is a foreign substance in the anti-drumming compound, which is not only harmless to the effectiveness of the anti-drumming compound, but surprisingly improves its acoustic effectiveness.
- the anti-drumming mass contains a gelling agent, which at a temperature of about 120 ° C within of about 10 - 12 minutes gelled so that the anti-drumming mass the stress in one of the paint shops upstream scrubber to remove dirt and withstand drawing oils.
- Gelling agents which meet the aforementioned conditions, are available very cheaply for around EUR 3 per kg, while possibly usable as an alternative Accelerators cost about EUR 50 per kg.
- the gelling agent changes the storage stability of the anti-drumming compound not and their applicability will not negatively influenced.
- the acoustic properties of the Anti-drumming mass is even improved by the gelling agent.
- Gelling agents can be used as gelling agents.
- An anti-drumming compound was tested in practice, in which the Gelling agent is an acrylic polymer based on methyl methacrylate and n-butyl methacrylate and its proportion is 1 - 10% by weight.
- the overall anti-drumming mass is optimally composed if it contains the following components: epoxy resin 40 - 45% by weight Hardener, thermosetting (dicyandiamide) 1 - 3% by weight accelerator 0.1 - 4% by weight chalk 45 - 55% by weight dye 0.04% by weight Thixotrophieicosstoff 1 - 5% by weight viscosity aids 0.5% by weight Gelling agent (methyl methacrylate) 1 - 10% by weight
- the invention permits various embodiments. To further clarify their basic principle hereinafter referred to a block diagram.
- the anti-drumming mass contains a gelling agent that is an acrylic polymer based on methyl methacrylic and n-butyl methacrylate is.
- the body shell then goes into a shell furnace 3, the curing process commonly used in automobile manufacturing of the adhesive present on the bodyshell serves and in which there is a temperature of about 120 ° C. and the body shell remains about 10 to 12 minutes.
- a pretreatment 4 follows, in particular with washers at temperatures from 50 to 60 ° C and pressures of 4 - 5 bar grease on the body shell be washed off. Phosphating is also carried out there the body shell. Close the pretreatment a cataphoretic dip painting 5 and a Drying process in an oven 6. In this oven 6 the temperature is 180 ° C. The body remains about 20 minutes in the oven 6. This will make the chemical Curing process of the anti-droning compound started and so far completed their painting in a painting station 7 can be done. You will close a paint oven 8 in which the paint and the anti-drumming compound completely dry or harden. The finished painted body then arrives at final assembly 9.
