Fireproof door core plate and preparation method thereof

Abstract

The invention discloses a fireproof door core plate, which comprises the following components in parts by weight: 10-100 parts of an inorganic material, 15-25 parts of water glass, 15-25 parts of a water glass curing agent, 5-10 parts of ethyl acetate, 50-70 parts of water and 5-10 parts of a water repellent agent. According to the invention, the product has the advantages of being simple in manufacturing process, low in price, safe, environment-friendly and high in strength.

Description

technical field [0001] The invention relates to the field of doors, in particular to a fireproof door core board and a preparation method thereof. Background technique [0002] The door core board is also the filling material filled in wooden doors, security doors and other doors. Especially in the field of anti-theft doors, the filling materials used are the most common. The filling materials currently used include honeycomb paper, foamed lightweight cement board and magnesium oxide board, among which the ones that have a better real fire prevention effect are Foamed cement boards and magnesium oxide boards, because they are made of inorganic materials, can withstand high temperatures of more than 1,000 degrees, and the production and preparation are simple. However, although the foamed cement boards on the market have certain strength, they are relatively expensive and heavy. It is more troublesome in production and handling, and magnesium oxide board (glass magnesium boa...

Especially in the field of anti-theft doors, the filling materials used are the most common. The filling materials currently used include honeycomb paper, foamed lightweight cement board and magnesium oxide board, among which the ones that have a better real fire prevention effect are Foamed cement boards and magnesium oxide boards, because they are made of inorganic materials, can withstand high temperatures of more than 1,000 degrees, and the production and preparation are simple. However, although the foamed cement boards on the market have certain strength, they are relatively expensive and heavy. It is more troublesome in production and handling, and magnesium oxide board (glass magnesium board) is one of the most common materials in the core board of anti-theft door fire doors. However, the current magnesium oxide board is not as strong as other boards, and it is easy to cause breakage during handling. Especially in the production process, workers will scrap it directly if they are careless, and the scrapping rate is relatively high. At the same time, the price is not very cheap.
