Description

Environment-friendly fireproof building base material and manufacturing method

The present invention relates to a fireproof building material and a production method thereof, in particular to an environmentally friendly fireproof building base material which is made of halogen-free polyethylene foam and does not generate toxic gas when heated, and a production method thereof.

In modern society, people are concentrated in cities, but urban land is limited, so the number of newly built houses has an increasing trend, which means that the population density per unit area continues to rise. If a fire occurs and cannot be quickly controlled, a single fire may be harmful. The number of people arriving has also risen accordingly. In order to prevent fires from causing regrets, my country has also established many standards related to fire-resistant building materials in order to suppress the spread of fires, especially in important public places, such as airports, stations, high-rise buildings and sub-leased suites, which require the use of flame-retardant or Non-combustible fireproof building decoration materials increase the time for people to escape.

The foaming material has many tiny air cells, which can prevent the temperature of the indoor flame from spreading to other areas. As a fireproof material, it can reduce the spreading speed of the fire. At the same time, the foaming material also has the effects of sound insulation and blocking outdoor changes in cold and heat. Foam material is very suitable for building fire protection. However, polyvinyl chloride is used as the conventional fireproof foam material. Although polyvinyl chloride has certain flame retardancy, because the matrix material contains chlorine, it will produce a large amount of toxic and corrosive hydrogen chloride and dioxin when heated and burned in the event of a fire. The smog of similar compounds causes secondary pollution, so it does not meet the requirements of environmental protection industry policies and is gradually being eliminated. Therefore, fireproof materials with environmental protection properties are needed to replace them.

In view of this, the inventors devote themselves to research and design, and hope to provide an environmentally friendly fireproof building substrate that will not cause toxic gases to harm the environment due to high temperatures. This is the motive of the present invention.

The main purpose of the present invention is to provide an environmentally friendly fireproof material, which can be widely used in various types of residences, will not release toxic gases to harm the environment during a fire, and can also provide good fireproof performance.

Therefore, the environment-friendly fireproof building substrate and manufacturing method of the present invention, the manufacturing method steps include: filling a mold, injecting liquid polyethylene into the mold; foaming, allowing bubbles to be generated in the liquid polyethylene to form a polyethylene foam board; and cutting Cut, cut the polyethylene foam board into a predetermined size as an environmentally friendly fireproof building base material for house compartments.

Before foaming, liquid polyethylene can be added with multiple aluminum hydroxide powders to enhance the flame resistance, or the cut polyethylene foam board can be laminated with a second heat insulation layer such as aluminum foil to enhance the performance of reflecting radiant heat.

The environment-friendly fireproof building base material manufactured by the invention can be matched with a decorative board as an indoor partition wall decoration to enhance the fireproof performance of a residence. The decorative board can be aluminum-plastic board, stone board, concrete board, fiber board, fiber cement board, magnesium oxide One of board, wood wool fiber cement board, gypsum board or calcium silicate board. If necessary during construction, a frame, such as a wooden or concrete frame, can be used to help fix the invention.

In order to further understand the features, characteristics and technical content of the present invention, please refer to the following detailed description of the present invention.

Please refer to the first to fourth figures. The above-mentioned figures illustrate the environmental protection and fireproof building substrate manufacturing method of the present invention. The steps include pouring mold S1 to inject liquid polyethylene into the mold; foaming S2 to make liquid polyethylene Bubbles are generated inside to form a polyethylene foam board; and cutting S3, the polyethylene foam board is cut into a predetermined size as an environmentally friendly fireproof building substrate 1 for house compartments.

In the step of filling the mold S1, the liquid polyethylene can be added with a plurality of aluminum hydroxide powders to enhance the flame resistance of the environmentally friendly fireproof building substrate 1.

After the environmentally friendly fireproof building substrate undergoes the cutting S3 step, it may further include a laminating step S4, in which the cut environmentally friendly fireproof building substrate 1 (polyethylene foam board) is attached to a second heat insulation layer 2 The second thermal insulation layer 2 can be aluminum foil, but it is not limited to this. The second thermal insulation layer 2 can be attached to a single surface or multiple surfaces of the environmentally friendly fireproof building substrate 1, and the second thermal insulation layer 2 can reflect radiant heat. Further enhance the high temperature resistance of environmentally friendly fireproof building substrates.

In the fifth and sixth figures, the environmentally friendly fireproof building base material 1 manufactured by the present invention can be used with a decorative panel 3 as an indoor partition wall decoration to enhance the fireproof performance of the residence. The decorative panel 3 can be aluminum-plastic panel, One of stone board, concrete board, fiber board, fiber cement board, magnesium oxide board, wood wool fiber cement board, gypsum board or calcium silicate board. If necessary during construction, a frame (not drawn), such as a wooden or concrete frame, can be used to help fix the invention.

After the present invention is installed on the partition wall, if a fire accident occurs in the room, the environmentally friendly fireproof building base material 1 can prevent the high temperature of the flame from spreading outside the room. With the synergistic effect of the second heat insulation layer 2 and the decorative board 3, the fire cannot The rapid spread can gain the escape time of residents and the time of firefighters for disaster relief. Even if the flame burns off the present invention finally, no toxic gas will be generated to harm the environment.

However, the above are only the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. Any changes and modifications that can be obviously made by those who are accustomed to the industry should be regarded as not deviating from them. The essence of the present invention.
