Abstract

The invention discloses a preparation method of a fire-retardant partition wall for space lease. The fire-retardant partition wall for space lease comprises a group of double-layer flame-retardant plate bodies and a filling layer arranged between the double-layer flame-retardant plate bodies, wherein the double-layer flame-retardant plate bodies are a flame-retardant polyvinyl chloride double-layer board material containing a flame-retardant smoke suppressant, and the flame retardant smoke suppressant is prepared through heating contact of an alkyl phosphinate as shown in a formula (I), tributyltin, tri-n-octylphosphine oxide and melamine at 220-280DEG C, wherein in the formula (I): R1 is C1-C6 alkyl or phenyl, R2 is C1-C6 alkyl or phenyl, M is a metal element, and n is a positive integerfrom 1 to 4. According to the preparation method of the fire-retardant partition wall for space lease, the flame-retardant smoke suppressant does not lose flame-retardant performance during a high-temperature processing process, and does not produce fragile substances; and the obtained fire-retardant partition wall has good mechanical properties, is flame-retardant, and is environmentally friendly, therefore, the fire-retardant partition wall has very high promotion and application values.

Description

technical field [0001] The invention relates to a flame-retardant partition wall, in particular to a preparation method of a flame-retardant partition wall for space leasing. 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 concerne...
