Abstract
The present invention relates to a method of manufacturing daub for a piano keyboard, which belongs to the technical field of the research and development of daub for a piano keyboard. The daub for a piano keyboard is used for fixing positions of round and flat pins on a keyboard. The present invention adopts the processes of padding, drying, shaping, etc. The present invention pads raw material daub into working fluid with water-repellent agents and oil-repellent agents, and then carries out the drying and the shaping processes and gets the daub. The daub which has been manufactured by the method has the characteristics of vermin prevention and moisture prevention, water repellence, etc. The currently existing adopted raw materials which are all made of pure wool and used to manufacture a musical instrument after drying treatment become moth-eaten easily as time passes by. The performance effect can be affected when the gap between a round and flat pin and a round and flat pin hole is blocked because of the imbibition of the material in moist coastal areas. The daub manufactured by the method of the present invention overcomes the various defects and is an ideal method of manufacturing daub.
Description
Technical field
The invention belongs to the development field of fingerboard with glue.
Background technology
In piano was made, the position of its keyboard flat pin must fix with the glue bar at present.But the raw material that uses is pure woollen woven, damages by worms easily.In addition, piano is in use over a long time coastal humid area, and glue makes moist easily, and when the wet water absorbent situation of making moist took place, glue will expand.Owing between flat pin and the pin-and-hole very little gap is arranged.Expand as pectin, will be with gap plug resistance.Make in playing, press key after, this key can not in time return bullet to original position.Influence playing effect.The domestic and international piano of problem manufacturing firm fails to solve always hereto.So the glue of saying the inventive method production at present also of no use is used in practice.
Summary of the invention
The purpose of this invention is to provide a kind of manufacturing and refuse the method for the moistureproof and fingerboard of not damaging by worms of water with glue.Product is applied to piano and makes, to solve the problem that existing glue exists.
The present invention is achieved by following scheme.
At first pad the preparation of working solution.In padding groove, inject ionized water, add water-repellent oil-repellent agent, crosslinked resin and catalyst then in proportion.Through stirring the material of adding is fully dissolved then.The working solution pH value requires 3～7.Then at normal temperatures with raw material (being commonly referred to as the Shen reaches) pad in padding working solution, the time of padding is 1～2 minute.Raw material after will padding again takes out, and dries in dryer.Time is 1～2 minute, and bake out temperature is at 80～100 ℃.Raw material after the oven dry will bake typing and handle.Baking temperature is at 150～180 ℃, and the time is 0.5～1 minute.After raw material baked typing, carry out surface coating, make glue.
Manufacture method of the present invention is simple, and easy operating adopts the glue of the inventive method manufacturing to have good water, the oil repellent refused, and the glue smooth surface after the processing has been saved the surface and has been coated with plumbous operation, reaches the lubricious effect of light equally.Contain chemical composition in the working solution because of padding, can prevent from effectively to damage by worms again.Particularly on water repellency, improve greatly, make the suction of not making moist of glue bar on the flat pin to remain on kilter.Can not influence playing effect.It is a kind of very good manufacture method of refusing glue.
The present invention does not have accompanying drawing
The specific embodiment
Technical scheme of the present invention is as follows:
1, pads the preparation of working solution
Technical formula
Weight ratio of constituents unit
Distilled water 1 L
Organic fluoride high molecular polymer 10～50 g
Crosslinked resin 10～30 g
Magnesium chloride 0.1～1 g
2, compound method
Earlier distilled water is joined and pad in the groove, padding groove is rectangle plastics system.Add with crosslinked resin with as the magnesium chloride of catalyst then,, it is mixed through fully stirring.The pH value of working solution is 3～7.
3, pad processing
At normal temperatures raw material cloth is padded in padding working solution, the time of padding is 1～2 minute.
4, oven dry and typing
Raw material after will padding takes out from padding in the groove, puts into the dryer baking, and the time is 1～2 minute, and baking temperature is at 80～100 ℃.Raw material after the oven dry will bake typing and handle.On 600 type hot melt adhesive machines, carry out.The raw material flatiron is smooth, typing.Baking temperature is at 150～180 ℃, and the time is 0.5～1 minute.
5, gluing
Raw material cloth after baking is carried out surface applied resin glued membrane.Make glue.
