Description

Semi-non-combustible building members and their manufacturing methods

The present invention relates to a semi-non-combustible building member and a manufacturing method thereof, and more specifically, to a semi-non-combustible building member including waste material, binder, and hardening agent, and a manufacturing method thereof, which is environmentally friendly and reduces production costs by using waste as the main material. It can be done, and relates to a semi-non-combustible building member and a manufacturing method thereof that are given semi-incombustibility by using a binder with semi-incombustible performance.

The total amount produced from 1950, when plastics first became widely used, to 2015 was approximately 8.3 billion tons, of which approximately 6.3 billion tons were discarded, and 79% of the discarded plastics were landfilled, left in mountains, oceans, etc., or were discarded. It is known. This waste plastic problem causes various industrial/environmental problems, and each country is aware of the problems related to its disposal and recycling and is actively seeking solutions.

This trend is no exception in Korea. Despite various environmentally friendly policies, the amount of plastic waste generated in Korea is steadily increasing, showing an average annual increase of 7.2% from 2012 to 2016. The proportion of recycled plastic is also increasing, but the plastic recycling rate only increased by an average of 3.1% per year over the same period, failing to slow the increasing trend of plastic waste generation. This problem was clearly revealed in the so-called 'garbage crisis' that occurred in 2019, and since then, the amount of waste plastic has increased exponentially as demand for delivery has surged due to the social distancing policy introduced due to the pandemic caused by COVID-19. , the problem of recycling and processing of waste plastic is ongoing.

Meanwhile, shells generated in the fishing industry are also not unrelated to the above background. According to the Ministry of Oceans and Fisheries, about 300,000 tons of oyster shells are produced every year in Korea, and only about 20% of this is used in limited areas such as feed and fertilizer, and the rest is discarded. As of 2021, it is estimated that more than 1 million tons of oyster shells are being left abandoned.

Technologies that promote recycling of wastes such as waste plastics and shells are being launched across various fields, and technologies that aim to recycle wastes such as waste plastics and shells and convert them into building members and industrial materials are also being launched. However, especially in the case of waste plastic, when converted into building members, industrial materials, etc., it is easy to catch fire due to the nature of the raw material, and if manufactured without considering this, it may have characteristics that are very vulnerable to fire.

After spraying water on one side of each member, spray 50 mL of food (soup), which is a contaminant that easily attaches in real life, and leave it for 48 hours while maintaining the temperature of 37.0 ± 0.1 ℃ and humidity of 85%. Afterwards, the antibacterial performance was evaluated by visually observing the mold colonies formed on the surface. As a result of observation, it was confirmed that the number of mold colonies increased in the order of the building member manufactured in Example 3, Comparative Sample 8, Comparative Sample 6, Comparative Sample 7, Comparative Sample 5, and the base member manufactured in Example 2. , especially in the case of the building member manufactured in Example 3, almost no mold colonies were observed on the test surface. This also appears to be due to the presence of the additive composition, the presence of each extract added to each composition, and the mixing ratio mixed in equal proportions, which significantly increases antibacterial performance.

In the above, the applicant has described preferred embodiments of the present invention, but such embodiments are only embodiments that implement the technical idea of the present invention, and no changes or modifications can be made to the present invention as long as the technical idea of the present invention is implemented. It should be interpreted as falling within the scope.
