Abstract

The invention discloses a preparation method for a flame-retarding partition wall for space rent. The preparation method comprises the steps that (1) flame retardants are prepared, specifically, alkylphosphinate shown as the formula (I), tributyltin, tri-n-octylphosphine oxide and melamine are heated at the temperature of 220-280 DEG C and make contact; (2) three-layer flame-retarding plate bodiesare prepared, specifically, first-layer materials, second-layer materials and third-layer materials are mixed respectively and then subjected to co-extrusion forming; and (3) a filling layer is gluedbetween the two three-layer flame-retarding plate bodies arranged oppositely, wherein the first-layer materials, the second-layer materials and the third-layer materials all contain the flame retardants. The flame retardants in plates used for the partition wall do not lose flame-retarding performance in the high-temperature processing process, and generating of fragile substances is not found either, mechanical performance is good, flame retarding and environmental friendliness are achieved, and quite high application and popularization value is achieved.

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 retardants include aluminum hydroxide, cerium hydroxide, magnesium hydroxide, halogenated flame retardants, phosphinates and polycyanamides, etc. Although the commonly used halogenated flame retardants are still widely used, due to Combustion will produce problems such as dioxin and poisonous gas after the fire, so that its harm to human health and the environment has attracted more ...
