Description

Spray can with spray head with adjustable stop element

The invention relates to a spray can according to the preamble of claim 1. Platelet-shaped metal pigments are brought for many years in the form of aerosols in the trade. This has the advantage over conventional painting with the aid of a paint gun that the platelet-shaped metal pigments can be applied locally to the substrate. For example, the use of aerosols is standard in automotive refinish. Since the platelet-shaped metal pigments are high-quality pigments, such aerosols are relatively expensive.

Compared with conventionally painted platelet-shaped

Metal pigments have the disadvantage that they are less well-oriented due to the aerosol sprayed metal pigments. In the case of optical applications, this leads to a less pronounced metallic effect (brilliance, light-dark-flop, opacity) and, in particular, to an increased amount

Cloud formation. In the case of zinc flakes as anti-corrosive pigment leads

CONFIRMATION COPY a poorer orientation of the platelets also leads to a reduction in the anti-corrosion properties. This is based on the electrochemical principle of the "sacrificial anode" and a barrier effect of the oxidized pigments Both mechanisms only work optimally with a good orientation of the zinc flakes after application: well-oriented pigments have a maximum high surface contact of the pigments with each other and thus a particularly good This is a prerequisite for optimal oxidation of the pigments, and well-oriented zinc flakes can also have an optimal barrier effect since they are the least effective

Allow spaces between the plates.

Another aspect is the simple dosage of aerosol application.

and wherein it is provided that the aerosol is filled with an aerosol comprising the following components:

a) platelet-shaped metallic effect pigments

b) water and / or organic / s solvents

c) binders

d) propellant.

The proposed spray can as described above, be formed.

The platelet-shaped metal pigments usually have an average size (d50) of from 3 to 50 μm, preferably from 5 to 25 μm. In particular, in a preferred embodiment, wherein the spray head on a central mounting portion of a valve device of

Spray can can be screwed on, there is another advantage: aerosols containing platelet-shaped metal pigments, due to the relatively large dimensions of the platelet-shaped metal pigments in the prior art often lead to clogging of the spray head. This in turn means that the contents of the can can not be emptied.

The platelet-shaped metallic effect pigments are preferably taken from the group consisting of aluminum pigments, zinc pigments, brass pigments, copper pigments, stainless-steel pigments or mixtures thereof. Particular preference is given to using aluminum pigments or zinc pigments or mixtures of these pigments.

Platelet-shaped zinc pigments are used for corrosion protection. Even in this case, however, an attractive appearance can be advantageous. Therefore, better orientation of the pigments, in addition to improved corrosion protection, also contributes to improved optical properties such as brilliance, light-dark-flop, and less cloudiness. In the case of platelet-shaped zinc pigments, preference is given to using 8-25% by weight and more preferably 10 to 20% by weight, based on the total weight of the aerosol.

In the case of platelet-shaped aluminum pigments, a smaller proportion tends to be used. This is based on the one hand on the lower density of aluminum (compared to zinc, stainless steel, copper, brass) and on the other hand, that in optical applications less than in the anti-corrosion pigmentation. Thus, the proportion of platelet-shaped

Aluminum pigments preferably 2.5 to 20 wt .-% and particularly preferably 5 to 15 wt .-%, based on the total weight of the aerosol.

In the case of platelet-shaped stainless steel, copper or brass pigments, preference is given to using from 2.5 to 25% by weight and more preferably from 8 to 20% by weight, based on the total weight of the aerosol.

Butyl methacrylate / methyl methacrylate acrylate resin used.

The propellant gases may be of the group consisting of propane, butane,

Dimethyl ether, N ₂ , CO2, compressed air and mixtures thereof, be taken. Particularly preferred are propane, butane and mixtures thereof. The aerosol may contain other components which are taken from the group consisting of additives, fillers, dry and their mixtures. The additives may be of the group consisting of anti-skinning additives,

By the screwing of the spray head 12 is a very reliable connection between the spray head 12 and the pressure vessel 11 made, which withstands rough operation use. The valve device 111 is connected in a gastight manner in the usual manner by crimping with the pressure vessel 11. The

Spray head frame 121 has a cup-shaped outer portion which engages over the valve means 111 together with the upper edge of the can.

The valve device 111 has a "female" valve, i.e. a valve that is not formed with a protruding valve stem, but with a valve seat arranged in a recess.

A cylindrical pressure piece 122 is in the Sprühkopfgestell 121st

stored linearly movable. The direction of movement is along the can axis 11a. The pressure piece 122 acts with its valve device 111

remote end face with a Sprühbetätigungstaster 123 together, which is designed as a one-armed lever which is mounted by means of a bearing pin 1231 in a fork-shaped bearing portion of the Sprühkopfgestells 121. With the pressure piece 122, a plunger tube 122s and a radially adjoining nozzle tube 122d are motion-connected. The plunger tube 122s and the

Nozzle tube 122d in the pressure piece 122 are rigidly arranged. In a preferred embodiment, the nozzle tube, ram tube and pressure piece are integrally formed as a plastic injection molded part. The plunger tube 122s may have an inner diameter of 1 to 1.4 mm, preferably 1.2 mm. The nozzle tube 122d may have an exit diameter of 0.4 to 0.6 mm, preferably 0.5 mm. Diameter. The spray material is supplied via a supply hose 111s, which is attached to a tubular inlet nozzle of the valve and the inlet rests on the bottom of the pressure vessel 11 is supplied. By pushing the spray actuation button 123 downwards - ie, clockwise about its axis of rotation in FIG. 3 - the plunger tube 122s acting in the can axis 11a presses the spring-loaded valve seat of the valve device 111 into the valve device so that an annular gap is formed around the valve seat through which the under pressure in the pressure vessel 11 Sprühgut past the valve seat passes through a introduced in the lower portion of the plunger tube 122s slot into the interior of the plunger tube 122s and from there into the perpendicular to the plunger tube 122s arranged nozzle tube 122d, which is closed by a nozzle 124. In the nozzle 124, the sprayed material is atomized. Depending on the degree of depression of the

Sprühbetätigungstasters 123 a more or less large flow of Sprühguts is set. In that shown in Figs. 1 to 4

The guide surface 127f may preferably cover an angle range α of 90 ° to 270 °, preferably of 150 ° to 190 °, wherein the guide surface 127f designed as a slide guide groove also provides end stops for the guide pin 125s. The end stops can be formed by the front ends of the guide groove. The surface guide element 127 can at the same time form a pivot bearing for the stop element 125 and be supported on the spray head frame 121. In an advantageous embodiment, the surface guide element 127 may be formed in one piece with the spray head frame 121 (FIG. 5).

The stop element 125 has a radially projecting adjusting handle, which is designed as an actuating arm 126. On the top of
