The paper corner protectors mainly include L-shaped paper corner protectors and U-shaped paper corner protectors, and of course, other types of paper corner protectors such as bent paper corner protectors, waterproof paper corner protectors, surrounding paper corner protectors and special-shaped paper corner protectors are also available. However, in the current market, L-shaped paper corner protectors are more. In order to meet the requirements of people, various L-shaped paper corner protectors appear in the market, for example, Chinese patent with application number 200910232346.3 discloses an L-shaped paper corner protector and a manufacturing method thereof, wherein the L-shaped paper corner protector comprises a paper L-shaped body, the end face of the body is L-shaped, and a continuous sawtooth structure is arranged on one side edge of the L-shaped body; the apex angle of the tooth top of the sawtooth structure is any angle less than 90 degrees, and is commonly 30 degrees and 45 degrees. The L-shaped paper corner protector with the sawteeth has the characteristics of easiness in packaging and material saving, but the top ends of the sawteeth arranged on the L-shaped body are sharp and hard, so that people are easily scratched in the production or use process, and the L-shaped paper corner protector is extremely unsafe. The paper corner protector has poor compression strength and bearing strength, is easy to break and absorb moisture to damage.
SUMMERY OF THE UTILITY MODEL
To above not enough, the utility model discloses the technical problem that solve is: the paper corner protector has the advantages of high strength, good shock resistance and moisture resistance, and safe and convenient use.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a paper angle bead, includes the L type paper base plate that forms by the integrative suppression of multilayer cardboard, interval seam evenly is equipped with continuous square strip on one side of L type paper base plate, multilayer cardboard is plastic layer, honeycomb core paper layer, compressive layer, corrugated paper layer, dampproof course from the upper surface of L type paper base plate to its bottom in proper order.
In the scheme, the compression resistance of the compression resistant layer is a nano calcium carbonate layer formed by coating a nano calcium carbonate material.
In the scheme, the moisture-proof layer can be a polysiloxane resin layer coated by a polysiloxane resin material, and the thickness of the moisture-proof layer is 0.1-0.5 mm.
In the scheme, the L-shaped paper substrate is a strip-shaped 90-degree bent paper tape.
In the above scheme, the plastic layer plays a role in preventing the packaged or supported object from being scratched or damaged, and the plastic layer can be a soft plastic layer made of a PP polypropylene material.
The utility model has the advantages that:
1. this paper angle bead is by the integrative L type paper base plate that suppresses and form of multilayer cardboard, multilayer cardboard is from last to being plastic layer, honeycomb core paper layer, compressive layer, corrugated paper layer, dampproof course down in proper order. The corrugated paper layer and the compression-resistant layer can improve the compression strength of the paper corner protector, the honeycomb core paper layer has the functions of impact resistance and shock absorption, the moisture-proof layer has the functions of water resistance and moisture resistance, and the plastic layer can effectively prevent the packaged or supported object from being scratched and damaged.
