Abstract

The invention discloses a flame-retardant double-layer board for space rental and a preparation method thereof. The method comprises the steps of co-extrusion moulding a first material and a second material, wherein the first layer material and the second layer material both contain a flame retardant and smoke suppressant, the weight content of the flame retardant and smoke suppressant in the first material is 20% to 200% higher than the weight content of the flame retardant and smoke suppressant in the second material, and the flame retardant and smoke suppressant is prepared by heating and contacting alkylphosphinate shown in formula (I), tributyltin and tri-n-octylphosphine oxide at 200 to 300 DEG C. The flame retardant and smoke suppressant in the board does not lose flame retardancy during the high temperature processing, and no formation of fragile substances is found, the flame-retardant double-layer board has good mechanical properties, flame retardancy, and environmental protection, and has high promotion and application value. (The formula (I) is shown in the description.).

Description

technical field [0001] The invention relates to a flame-retardant board, in particular to a flame-retardant double-layer board for space leasing and a preparation method thereof. Background technique [0002] With the development of economy and society and the accelerated pace of life and work, most office areas are no longer fixed reinforced concrete houses, but more office spaces divided in a building. These spaces are leased to Target customers. Since these spaces often accommodate a large number of people, fire resistance is the most important requirement for leased spaces. Commonly used flame retardant and smoke suppressants include aluminum hydroxide, cerium hydroxide, magnesium hydroxide, halogen flame retardant and smoke suppressant, phosphinate and polycyanamide, etc., although the commonly used halogen flame retardant and smoke suppressant It is still widely used, but due to problems such as burning dioxins and poisonous gas after a fire, it is more and more conc...
