preparation example Construction

[0032]The present invention also provides a method for preparing a double-layer flame-retardant board, including co-extruding the first material and the second material; wherein, both the first material and the second material contain a flame-retardant and smoke suppressant, wherein, The weight content of the flame retardant and smoke suppressant in the first material is 20%-200% higher than that in the second material; wherein, the flame retardant and smoke suppressant is the flame retardant and smoke suppressant provided by the present invention as described above.

[0033] During this process, the flame retardant and smoke suppressant in the double-layer flame-retardant board of the present invention will not lose its flame-retardant performance during high-temperature processing, and no brittle substances are found. Good mechanical properties, flame retardant, environmental protection. The content of the flame retardant and smoke suppressant in the two layers of the double...

Abstract

The invention discloses a flame-retardant partition wall for space leasing. The flame-retardant partition wall comprises a set of two-layer flame-retardant plate bodies and a filling layer arranged between the two-layer flame-retardant plate bodies; the two-layer flame-retardant plate bodies are flame-retardant polyvinyl chloride double-layer plate materials containing flame-retardant smoke inhibitors, and the flame-retardant smoke inhibitors are prepared and obtained after alkyl hypophosphite, tributyltin and trioctylphosphine oxide as shown in a formula (I) are subjected to heating contact at the temperature of 200-300 DEG C; and 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 integer from 1 to 4. According to the flame-retardant partition wall for space leasing, the flame-retardant smoke inhibitors used in the flame-retardant plate bodies do not lose the flame-retardant property in the high temperature machiningprocess, generating of brittle materials is also not found, and the obtained flame-retardant plate materials are good in mechanical properties, flame retardant and environmentally friendly.

Description

technical field [0001] The present invention relates to a flame retardant partition wall, in particular to 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 concerned about the harm...
