Description

A new type of water-resistant and abrasive-resistant sandpaper

technical field

The utility model relates to the technical field of abrasive tools, in particular to a novel water-resistant and grinding-resistant sandpaper.

Background technique

Sandpaper, commonly known as sand skin, is a material for grinding. During the use of sandpaper, uneven sanding often occurs. During the sanding process, the abrasive particles continue to fall off, and are easily damaged by water. The reason for this phenomenon is that the degree of adhesion of the abrasive particles is limited. Some abrasive particles have a low degree of adhesion and will fall off when pushed lightly. There is no waterproof layer on the surface, and it will be damaged after getting wet. At the beginning of use, the abrasive particles on the surface of the sandpaper are evenly distributed, and once used, they will fall off, so the number of abrasive particles in some parts of the sandpaper is significantly less than that in other places, resulting in uneven sanding and easy damage when wet The problem.

Utility model content

The purpose of this utility model is to provide a new type of water-resistant and abrasive-resistant sandpaper to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions: a new type of water-resistant and abrasive-resistant sandpaper, including a paint waterproof layer, a paper base layer, a primer layer and an abrasive layer; the paint waterproof layer covers the lower surface of the paper base layer; The primer layer is fixed on the upper surface of the paper base layer; the abrasive material layer is fixed on the primer layer.

Further, the material of the abrasive layer is high silicon carbide.

Further, the abrasive layer is evenly distributed on the primer layer.

Compared with the prior art, the utility model has the beneficial effects that: the new water-resistant and abrasive-resistant water sandpaper can provide excellent surface treatment effect and continuous grinding ability; the paper base layer has a flexible back base, good adhesion, and is easy to use; When used, it can be much better than the uniform effect and applicability of sandpaper in the prior art.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of novel water-resistant and grinding-resistant water sandpaper, comprise paint waterproof layer 1, paper base layer 2, primer layer 3 and abrasive material layer 4; Said paint waterproof layer 1 Covering the lower surface of the paper base layer 2; the primer layer 3 is fixed on the upper surface of the paper base layer 2; the abrasive material layer 4 is fixed on the primer layer 3.

Further, the material of the abrasive layer 4 is high silicon carbide.

Further, the abrasive layer 4 is evenly distributed on the primer layer 3 .

When the utility model is designed: the new water-resistant and grinding-resistant water sandpaper uses high silicon carbide as the abrasive on the abrasive layer 4, and the abrasive particles are flattened to form the abrasive layer 4, and the abrasive layer 4 is fixed on the paper base 2 through the primer layer 3 Top; the primer layer 3 uses composite materials to allow the abrasive particles that are not firmly connected, that is, to fall off, to gather together, so that the dropped abrasive particles can adhere to their original positions and continue to work, so that the sandpaper can achieve sanding when used. Uniform effect and increase the service life of the sandpaper; the paper base 2 is used to bear the effect of abrasive particles, using hard cardboard; adding a paint waterproof layer 1 on the surface of the paper base 2, so that when using this new water-resistant and abrasive-resistant water sandpaper, it can be clearly Increase the service life and will not be damaged when working with water, making the grinding products more uniform and regular.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacements and modifications, the scope of the present utility model is defined by the appended claims and their equivalents.
