Description

Brush and manufacture method thereof

Background of invention

Technical field

The present invention relates to the brush of the most suitable brushing water paint, and the method for making this brush.

Background technology

Broadly, according to bristle (bristle) material, brush can be divided into two classes.One class is an animal wool hair style brush, and its bristle uses the hair of goat, horse, pig etc.; Another kind of is synthetic fibers type brush, and its bristle is made by synthetic resin such as polybutylene terephthalate (PBT) (PBT).

Owing to make the cuticular effect that bristle surface is coarse relatively, animal wool hair style brush keeps or the better performances of release coatings, and along with the kind of animal or cut the animal body region of hair, aspect elasticity nuance is arranged.These characteristics provide such advantage, promptly by selecting to be fit to the animal hair type of every kind of special-purpose, can make the very big brush of characteristic variations.

On the other hand, synthetic fibers type brush has the high advantage of wearability, and the use of present this brush is in continuous increase.Yet because different with the bristle of animal hair, the bristle surface of synthetic fibers type brush does not have cuticula, so its surface is smooth, they keep or the aspect of performance effect of release coatings relatively poor, and on elasticity, be difficult to have nuance.Therefore, as the conveniency and the operating efficiency aspect of coating brushing, they are poorer than the animal hair brush in some aspects.

Simultaneously, coating also has two big class, oil paint and water paints.Oil paint with VOC (VOC) solvent such as solvent or diluent (thinner) dilution has good coating performance.But, because contained VOC and to the adverse effect of human health, is now limiting their use gradually to the destruction of global environment in this oil paint.

On the contrary, without solvent or diluent or with the advantage of the water paint of other VOC dilution be to the friendly of global environment with to the relative very little adverse effect of human health.And, the past water paint aspect coating performance than oil paint difference, but because the improvement of technology in recent years, suitable with oil paint at water paint aspect this.In addition, water paint has the advantage than oil paint fast drying.Because these advantages, water paint more and more tends to replace oil paint in many applications.

Incidentally, for the brushing water paint, synthetic fibers type brush uses manyly than animal wool hair style brush usually, because in a single day animal wool hair style brush is used for just can not being used as brush again behind the brushing water paint, is very uneconomic therefore.Like this, because the surface roughness of animal wool hair style brush, coating is easy to arrive between the bristle of brush, and in case the quick-drying water paint that sticks on the bristle becomes dry, can not be removed easily even wash with water.Therefore, as shown in Figure 2, the root 1a of bristle 1 hardens, and perhaps the top 1b of bristle is fan-shaped and scatters.

If the root 1a hardening of bristle 1 can not make brush move the very difficulty thereby brushing work meeting becomes in the mode (for example revolution or other operation) of brushing need of work.Perhaps, if the top 1b of bristle 1 scatters, can not finish coating nattily.Like this, if animal wool hair style brush is used for the brushing water paint, in most of the cases just have to brush is abandoned after only using once, therefore using animal wool hair style brush brushing water paint is irrational economically, and this is a general knowledge for those skilled in the art.

Therefore on the other hand, synthetic fibers type brush makes that coating is not easy to stick on the bristle because its bristle surface does not have concavo-convexly, even when being used for the brushing water paint, also can remove coating by washings such as waters.Therefore, the root of bristle can not harden, and the top 1b of bristle can not scatter yet.Like this, synthetic fibers type brush promptly is used in the brushing water paint and also can uses many times, is economical and practical therefore.Because their advantage, those skilled in the art thinks that synthetic fibers type brush more is applicable to the brushing water paint.

In addition, because those skilled in the art generally believes that synthetic fibers type brush more is applicable to the brushing water paint, therefore do not find that in the document of prior art relevant animal wool hair style brush can be effective to the record of this purpose.

As mentioned above, therefore synthetic fibers type brush has reduced operating efficiency because the performance of its relatively poor reservation or release coatings has to immerse more continually in the coating at the brushing duration of work.In addition, owing to the nuance on the elasticity that can not provide animal hair to provide, therefore, the synthetic fibers brush is also poor than animal wool hair style brush aspect the conveniency of coating brushing.

Summary of the invention

The purpose of this invention is to provide a kind of brush and the method that is used to make this brush, even described brush is after being used for the brushing water paint, the bristle root can not harden and can not scatter in the top of bristle, has kept the premium properties of animal hair reservation and release coatings simultaneously.

To achieve these goals, the present invention has following feature.

According to a first aspect of the invention, brush uses the pH value to remain the animal hair of neutrality or alkalescence as its bristle.

According to a second aspect of the invention, have bristle according to the brush of first aspect, wherein 1%～40% bristle is made by composite fibre materials.

According to a third aspect of the present invention, on the bar that bristle is fixed on brush after, the bristle with alkaline rinse washing brush carries out drying afterwards.

According to a fourth aspect of the present invention, wash bristle by alcaliotropism washing lotion brushing dither according to the brush of the 3rd aspect.

Fig. 1 shows the overall diagram (overall view) of brush, and this brush is a preferred embodiment of the present invention; With

Fig. 2 shows the overall diagram of conventional brush.

Specific embodiments

As shown in Figure 1, brush has the bristle 4 that is fixed on bar 2 one ends via supporter 3.In the present embodiment of the present invention, bristle 4 is made by animal hair.Have to be noted that also these bristles 4 are not only combing, and with the alkaline rinse washing and carried out drying.

Because alkaline rinse height aspect decontamination is effective, removed with alkaline rinse washing animal hair and to have sticked to its lip-deep tiny dirt and grease.As a result, smoothness of the surface improves, and smooth degree is suitable with the synthetic fibers bristle.This surface smoothness makes that water paint is difficult to stick on the bristle, and this also makes water paint easier being removed when washings such as water.

In addition, though the person's character of animal hair is a subacidity, by making it become neutrality or alkalescence with the alkaline rinse washing.Therefore, in the present embodiment of the present invention, bristle 4 is made by the animal hair that is processed into neutrality or alkalescence.The reason that this bristle 4 is carried out neutralisation will make an explanation below.Found through experiments water paint can hardening when contacting with acidic materials.The pH estimated value of animal hair shows that also they are slightly acidic.These discoveries show that when animal wool hair style brush is used for the brushing water paint because the subacidity of bristle 4, bristle 4 hardens easily.

According to this viewpoint, in embodying brush of the present invention, by making bristle 4 become neutrality or alkalescence with alkaline rinse washing bristle 4 in advance.By making bristle 4 become neutrality or alkalescence in this mode, even bristle 4 contacts with water paint, the sclerosis of coating also can be delayed.And, because the surface of bristle is smooth as mentioned above, can remove the water paint that sticks on the bristle effectively by washing bristles such as waters.Therefore, the root 4a hardening third that can prevent bristle 4 prevents that the top 4b of bristle 4 from scattering.

The alkalescence of washing lotion can be weak or strong.Washing lotion only need be alkaline, but is to use the strong basicity washing lotion adverse effect to be arranged to the elasticity of bristle.Therefore in the present embodiment, be that 8～10 alkalescent washing lotion is washed bristle, the further dilute with water of this washing lotion with pH.

In addition, only to need be nonacid to washed bristle.They can be neutrality or alkaline.

In addition, as mentioned above, owing to removed tiny dirt and grease that bristle surface adheres in washing described in the present embodiment, water paint does not adhere to any dirt.If water paint itself adheres to dirt and sclerosis, then bristle 4 can hardening.But, if the same, remove the dirt of bristle surface fully in advance with the present embodiment, then do not have water paint can stick on the bristle 4 and it is hardened.Therefore, can more effectively prevent to stick to the sclerosis problem of the coating on the bristle 4 root 4a and the problem of scattering of bristle 4 top 4b.

Incidentally, wash the water imbibition of 4 pairs of animal hairs of bristle or the revolution of brush or the conveniency of other operation with alkaline rinse as mentioned above and have no significant effect (if any).

Then, be described below the method for making this brush.

At first, prune animal hair to predetermined length, and place it in bunchy together, the size of every bundle satisfies the requirement of brush.Each bundle of these bristle 4 bundles is fixed to supporter 3.After bristle 4 being fixed to supporter 3, supporter 3 is fixed on an end of bar 2 in this mode.

Bristle 4 is fixed on after the end of bar 2 by supporter 3, bristle 4 is immersed alkaline rinses and washs with it.This alkaline rinse can be weakly alkaline or alkaline.But,, in the present embodiment, be that 8～10 alkalescent washing lotion is washed bristle, the further dilute with water of this washing lotion with pH as mentioned above owing to use alkaline washing lotion adverse effect to be arranged to the elasticity of bristle.

In addition, the present embodiment can be used supersonic wave cleaning machine washing bristle 4.This supersonic wave cleaning machine is known device, and it disposes the container of preserving washing lotion and with the vibrating device of the washing lotion in the frequency vibration container of per second several ten thousand times.Owing to can vibration be sent to bristle via washing lotion with this supersonic wave cleaning machine (playing a part) washing bristle 4, therefore fully remove tiny dirt and the grease that sticks on the every bristle.And because vibration makes every bristle all contact with alkaline rinse, so the pH value of bristle can become neutrality or alkalescence from subacidity effectively.

In addition, although supersonic wave cleaning machine is used to wash bristle in the present embodiment, using other any device that is different from supersonic wave cleaning machine is consistent with the present invention undoubtedly.

As mentioned above, bristle 4 is immersed alkaline rinse a period of time and with after the washing lotion washing, takes out bristle and dry from washing lotion.When the bristle bone dry, brush completes.

Incidentally, also it is contemplated that before bristle 4 is fixed to bar 2, animal hair is immersed in the alkaline rinse.Yet, before securing it to bar 2, may cause some variation on the hair characteristic with alkaline rinse washing bristle 4, thereby will making that being difficult to fitly keeps together hair to make, these variations make the brush comparatively difficulty that becomes.But, wash them again after in advance being fixed on the bristle of bunchy on the bar, can eliminate making the bristle unordered and difficult possibility that is made into brush that becomes.

In addition, although the hypothesis of the bristle in the present embodiment is made up of 100% animal hair, the bristle 4 that 100% animal hair is made is proved to be the elasticity deficiency.For example, in fact experiment show, when the concentration that increases washing lotion when strengthening its clean result, the elasticity of bristle 4 is lost.According to this discovery, will mix with animal hair with about 30% ratio by the bristle that synthetic fibers (as polybutylene terephthalate (PBT)) formed.Promptly use the alkaline rinse washing, the elasticity of synthetic fibers bristle can be not influenced yet.Therefore, will have certain flexible synthetic fibers and mix with animal hair and form bristle 4, the integral, flexible that keeps bristle will be higher than the elasticity of the brush that 100% animal hair makes.And because the synthetic fibers bristle is neutral in essence, so the mixture of they and animal hair can not cause the sclerosis of water paint.

Yet if the ratio of synthetic fibers bristle surpasses 30%, animal hair will be lost more or less in the exclusive nuance of brushing aspect of performance.Therefore, the mixed proportion of synthetic fibers and animal hair is 1～30%, and is desirable, must not surpass 40%.

According to a first aspect of the invention, even use brush brushing water paint, can prevent that also the root hardening and the top of its bristle from scattering.Also kept the excellent properties of animal hair aspect reservation or release coatings simultaneously.Therefore, when keeping the animal hair unique advantage, described brush can be used for the brushing of water paint repeatedly.

The elasticity that can keep according to a second aspect of the invention, bristle.

According to a third aspect of the present invention, bristle can fitly keep together.

According to a fourth aspect of the present invention, can remove tiny dirt and the grease that sticks to bristle surface effectively.In addition, because vibration makes every bristle all contact with alkaline rinse, so the pH value of animal hair can become neutrality or alkalescence from subacidity effectively.
