Abstract

The invention discloses a naturally biodegradable paint roller, which includes a roller body. The roller body includes fur and a hose. The fur is sleeved on the surface of the hose. Cover plates are provided on both sides of the hose. The middle part of the cover plate A rotating groove is provided, and a number of teeth are provided on both sides of the cover plate. The cover plate is clamped on both sides of the hose through the teeth. The fur is woven from natural fiber mixed yarn and yarn with added microbial-induced degradation agent. The hose is made of PP plastic and extruded with a microbial-induced degradation agent. When the hose and fur are buried in the soil of the landfill, the microorganisms in nature will interact with them if there is sufficient water. The polymers of the fibers in the hose and fur undergo hydrolysis and oxidation reduction, which can degrade the fur. The hose gradually becomes thinner and lighter, and gradually returns to the natural environment for natural degradation. The roller can also be used in the field of roller accessories such as sweeping robots and vacuum cleaners.

Description

A naturally biodegradable paint roller

Technical field

The invention belongs to the technical field of rollers, and specifically relates to a naturally biodegradable paint roller.

Background technique

A roller brush is a tool for rolling paint over a large area. It is often used when rolling paint over a large area in daily building decoration projects.

Existing paint rollers are limited by their durability. As the number of uses increases, the rollers may become worn, deformed, or cracked, making them unable to be used again. They are often discarded or difficult to recycle, resulting in a large amount of plastic waste. It is produced and cannot be degraded naturally, causing great environmental pollution.

Contents of the invention

The object of the present invention is to provide a naturally biodegradable paint roller to solve the problems raised in the above background art.

In order to achieve the above object, the present invention provides the following technical solution: a naturally biodegradable paint roller, including:

The roller body includes fur and a hose, and the fur is sleeved on the surface of the hose.

Preferably, cover plates are provided on both sides of the hose, and a rotation groove is provided in the middle of the cover plate. A number of teeth are provided on both sides of the cover plate, and the cover plate is clamped to both sides of the hose through the teeth.

Preferably, the fur is made of a natural fiber mixed yarn and a yarn with a microbial-induced degradation agent added, and the hose is a polypropylene pp pipe made of PP plastic with a microbial-induced degradation agent added.

Technical effects and advantages of the present invention: The naturally biodegradable paint roller includes a roller body. The roller body includes fur and a rubber hose. The fur is spun with a yarn mixed with natural fibers and a yarn with a microbial-induced degradation agent added during the spinning process. The made fur has good biodegradability and renewable properties. The hose is made of polypropylene pp pipe made of PP plastic and added with microbial-induced degradation agent. When the hose and fur made of biodegradable materials are buried in the landfill, In the soil of the burial site, when the water content is sufficient, the microorganisms in nature will undergo hydrolysis and oxidation reduction with the polymers of the fibers in the hoses and furs. The biodegradable additives in the fibers will help the microorganisms and bacteria to biodegrade the fibers. During the entire decomposition process, the degradable fur and hose gradually become thinner and lighter, and gradually return to the natural environment, thereby degrading naturally.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

The present invention provides a naturally biodegradable paint roller as shown in Figures 1-3, including:

The roller body 1 includes fur 2 and a rubber hose 3. The fur 2 is sleeved on the surface of the hose 3.

There are cover plates 4 on both sides of the rubber sleeve 3, and a rotation groove 5 is provided in the middle of the cover plate 4. There are a number of teeth 6 on both sides of the cover plate 4, and the cover plate 4 is engaged by the teeth 6. On both sides of the hose 3, the hose 3 is rotatably connected to the hand-held handle through the rotating grooves 5 on both sides of the cover plate 4, so that paint can be applied.

The fur 2 is made of a natural fiber mixed yarn and a yarn with a microbial-induced degradation agent added, and the hose 3 is a polypropylene pp pipe made of PP plastic with a microbial-induced degradation agent added.

The naturally biodegradable paint roller includes a roller body 1. The roller body 1 includes a fur 2 and a rubber hose 3. The fur 2 is made by spinning a natural fiber mixed yarn and a yarn with a microbial-induced degradation agent added during the spinning process. After the weaving is completed, the fur has good biodegradability and reproducibility. The hose 3 is made of PP plastic and a microbial-induced degradation agent is added to the polypropylene pp pipe. The hose 3 and fur 2 are made of biodegradable materials. Buried in the soil of the landfill, the microorganisms in nature will hydrolyze and redox with the polymers of the fibers in the hose 3 and the fur 2 if the water content is sufficient. The biodegradable additives in the fibers will help the microorganisms and bacteria The fibers are biodegraded. During the entire decomposition process, the degradable fur 2 and the hose 3 gradually become thinner and lighter, and gradually return to the natural environment, thereby degrading naturally.

The drum body 1 of the present invention can naturally biodegrade in landfills/anaerobic digesters/marine environments: the test is based on ASTM D5511/GB/T 33797 or ASTM D6691/EN 15985:2014, and the entire degradation process does not Requires additional equipment and energy.

Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still The technical solutions described in the foregoing embodiments may be modified, or equivalent substitutions may be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in within the protection scope of the present invention.
