Abstract
The invention relates to the field of C09D191/06, in particular to a high-lubricity packaging coating and a preparation method thereof, wherein the preparation raw materials comprise the following components in parts by weight: 80-150 parts of oily base material, 0-10 parts of oily diluent, 0-5 parts but not 0 part of filler and 0.1-2 parts of auxiliary agent. By adding the oil base materials such as silicone oil, polyolefin oil, mineral oil, chlorinated paraffin and the like, particularly the chlorinated paraffin, the packaging coating can effectively prevent external moisture from entering after being coated inside the PE rubber tube, simultaneously reduces the friction between the bottom cover and the inner wall of the rubber bottle, has a lubricating effect, cannot cause the harm of swelling to the rubber bottle, and cannot influence the performance of the rubber cement in the tube.
Description
Technical Field
The invention relates to the field of C09D191/06, in particular to a high-lubricity packaging coating and a preparation method thereof.
Background
The single-component silicone adhesive is a moisture curing type sealant, is very sensitive to water vapor in air, and has a plurality of packaging and subpackaging modes in the market at present, such as an iron 200L barrel, an aluminum toothpaste tube, a composite aluminum film flexible package, a PP plastic barrel, an HDPE plastic tube and the like, wherein 300mL of the HDPE plastic tube is most widely applied and consists of a cylindrical rubber tube and a piston type bottom cover, and the structure brings excellent convenience and popularity, and simultaneously brings the defects of poor water resistance, easiness in tube explosion and the like. The reason is mainly as follows: the water resistance of the structure is mainly determined by the contact area, the configuration and the contact surface tightness of the bottom cover and the pipe wall, in order to achieve good water vapor resistance, the bottom cover is in a conical cylinder shape, the maximum outer diameter of the bottom cover is slightly larger than the inner diameter of the rubber pipe, so that certain elastic stress exists between the bottom cover and the rubber pipe, if the stress is too small, the bottom cover is easy to slide, the force required during rubber extrusion is small, the operation is convenient, and the water resistance is reduced; if the stress is too large, the friction force between the bottom cover and the inner wall of the rubber tube is large, the extrusion performance is poor, and the rubber tube is easy to expand or even burst under the action of the stress for a long time. Therefore, in the actual production process, only the treatment is compromised, the shelf life of most hard-backed one-component silicone adhesives is about 9 months, and in the later period of storage, partial adhesive at the bottom cover is often found to be cured, so that the workability is reduced, and the bottom of the alcohol-type adhesive is also yellowed.
CN201510865693.5 discloses a preparation method of a mixed emulsion type packaging coating, wherein isophorone diisocyanate and other substances and mica are used as fillers, the prepared coating has strong stability and adhesive force, but if the coating is applied to the inside of a silicone adhesive HDPE plastic pipe as a coating, the coating has good compatibility with HDPE, and the colloid is easy to deteriorate.
