Abstract

A method of manufacturing an article comprising the steps of performing at least one manufacturing operation on at least one component of the article, applying paint to the or each component after performing said at least one manufacturing operation, applying a strippable coating of polyvinyl alcohol to the painted surface of the or each component, thereafter performing at least one further manufacturing operation on the or each component and thereafter removing the strippable coating.

Description

SPECIFICATION Method of manufacturing Description of invention This invention relates to a method of manufacturing.
According to one aspect of the invention we provide a method of manufacturing an article comprising the steps of performing at least one manufacturing operation on at least one component of the article, applying point to the or each component after performing said at least one manufacturing operation, applying a strippable coating of polyvinyl alcohol to the painted surface ofthe or each component, thereafter perform- ing at least one further manufacturing operation on the or each component and thereafter removing the strippable coating.
The invention is particularly suitable for use in a production line method of manufacture when a work location is advanced along a predetermined path past a number of work stations whereat manufacturing operations are performed on at least one component at the work location so as to manufacture the article.
In this case the or each component is painted after the work location has past at least one work station and before the work location has past the last work station.
According to another aspect of the present invention, we provide a method of manufacturing an article according to the first aspect wherein after performing a last manufacturing operation on the or each component a further protective coating is applied to the article over the polyvinyl alcohol.
The article may then be stored or transported as desired and then the polyvinyl alcohol removed together with the further protective coating by stripping off the strippable coating of polyvinyl alcohol.
The further protective coating maybe a wax, alkali soluble polymer, or any other protective coating which has no interaction with the polyvinyl alcohol base and provides long term weathering protection.
For example, where the article is a vehicle, frequently the vehicle is stored for a relatively long period until it is desired to be transported to a distributor or other retailer. It is accordingly necessaryforthe vehicle to be protected from the enviroment both during the storage period and during transport.
Hitherto, this has necessitated a messy and labour intensive operation, such as steam cleaning, to remove the protective wax. The present invention overcomes this problem by permitting the wax or the like further protective coating to be removed simply by stripping offthe polyvinyl alcohol coating.
The article may be a motor vehicle or other article such as a refrigerator, washing machine or the like.
Preferably the polyvinyl alcohol is applied in the form of an aqueous solution and is internally plasticised but may also be externally plasticised with additives such as polyethylene glycol, glycerine, or other glycols.
The aqueous solution may contain minor additives such as a biocide, a wetting agent and a corrosion inhibitor.
The polyvinyl alcohol coating may be pigmented or coloured with a die.
The aqueous solution may comprise 8-40% plasticised polyvinyl alcohol 0-7% Polyethylene glycol orotherplasticisor Upto 2% minor additions Balance water.
Preferably, the aqueous solution comprises about 25% Polyvinyl alcohol (internally plasticised) Upto2% minoradditions Balance water.
Or alternatively the aqueous solution may comprise 25% Polyvinyl alcohol 3% Polyethylene glycol or other plasticiser Upto2% Minoradditions Balance Water The plasticiser may have a molecularweight in the region of 200.
The aqueous solution may additionally comprise up to 7.5%filler or pigment or die.
The paint to which the coating is applied may be epoxy, alkyd, acrylic, cellulose, or acid catalysed touch-up paint, or other paint.
An embodiment of the invention will now be described in more detail by way of example.
In this example the article to be manufactured is a motor car. The car is manufactured in conventional manner using a production line manufacturing technique in which a work station is advanced along a production line track past a plurality of work stations at which manufacturing operations (such as adding com ponents to the work station or manipulating a component at the work station) are performed on the com- ponents.
At an appropriate stage along the production line the bodywork of the motor car is painted. Generally, the paintwill be applied to the bodywork before the bodywork is introduced as a component or componentsto the production line, and fitted to the other components ofthe vehicle. In order to protect the paintwork during assemblyto the other components and thereafter when other manufacturing operations are carried out on the motor car, an aqueous solution comprising 25% of internally plasticised polyvinyl alcohol, and approximately 2% of minor additives comprising a biocide, a wetting agent and a corrosion inhibitor is applied by a conventional spraying technique. If desired, the solution may be applied by any other desired technique such as airless spraying.
The aqueous solution dries to provide a peelable coating and this is left in position on the motor car until manufacture has been completed.
Atthis stage the coating can be easily stripped from the motor car simply by peeling if off.
If desired the polyvinyl alcohol coating may be retained on the vehicle and a further protective coating, as described hereinbefore, applied to protect the vehicle during prolonged storage, for example before the car is required to be delivered to a distributor or other retailer.
When the car is ultimately atthe distributor or other retailer it is simple to remove the further protective coating together with the polyvinyl alcohol simply by peeling off the polyvinyl alcohol coating and thus removing with it the further protective coating. This avoids the necessity for messy steam cleaning operationswhich have hitherto been necessary.
If desired the aqueous solution of polyvinyl alcohol may have other compositions as explained here inbefore and may contain upto 7.5%filIer, pigment ordie.
In the present example the motor vehicle is painted with a modified alkyd paint but the invention may be applied to articles which are coated with other paints such as epoxy, acrylic, cellulose and acid catalysed touch-up paints.
The plasticised polyvinyl alcohol coating does not react with such paints and thus provides a suitable protective film for painted articles.
The invention may be applied to any article not only a motor car or other vehicle for example, domestic appliances such as a refrigerator orwashing machine and also to aircraft, buses, lorries, and tractors as typical examples.
In this specification compositions are expressed in percent by weight.
