Abstract

The invention discloses a flame-retardant board for leasing space and a preparation method thereof. The preparation method comprises the following steps: mixing polyvinyl chloride, a filler, a stabilizing agent, stearic acid, an ACR modifier and a flame-retardation and smoke-suppression agent, and then subjecting the obtained mixture to extrusion molding. The flame-retardation and smoke-suppression agent is prepared by subjecting alkyl phosphinate as shown in a formula (I) which is described in the specification, tributyltin and trioctylphosphine oxide to heating and contacting at 200 to 300 DEG C. In the formula (I), R1 is a C1-6 alkyl group or a phenyl group; R2 is a C1-6 alkyl group or a phenyl group; M is a metallic element; and n is number in a range of 1 to 4. The flame-retardation agent in the board does not lose flame retardation performance during high-temperature processing, and formation of brittle substances is not found; and the flame-retardant board has good mechanical properties, flame retardation performance, environment friendliness and high promotion and application value.

Description

technical field [0001] The invention relates to a flame-retardant plate, in particular to a flame-retardant plate 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 concerned about t...
