Embodiment 1

[0024] According to the formula of Example 1 in Table 1, the specific preparation steps of the Class A fire-resistant aluminum-plastic plate core special material and its preparation method are as follows:

[0025] (1) Dry the raw magnesium hydroxide powder in a constant temperature drying oven at 120°C for 2 hours;

[0026](2) Use polymer compatibilizer, crosslinking agent, dispersant and coupling agent to pretreat the dried magnesium hydroxide, and the selected polymer compatibilizer PS-g- (epoxy modified PS) , cross-linking agent 2,5-dimethyl-2,5-di-tert-butylperoxyhexane, dispersant polyethylene wax, silane coupling agent (AMEO) and magnesium hydroxide are dried and mixed in a high-speed mixer Evenly, the pretreated magnesium hydroxide flame retardant is obtained. The stirring speed of the high-speed mixer is 2000r / min, the stirring time is 10min, and the mixing temperature is 120°C;

[0027] (3) According to the formula in Table 1, weigh high-compatibility resin or resi...

Abstract

The invention relates to an aluminum-plastic compound board sandwich layer material, in particular to a material special for a level-A fire-proof aluminum-plastic board core and a preparation method thereof. An inorganic flame retardant, i.e., magnesium hydroxide is taken as a flame retardant, and a high filling technology is adopted. Aids such as a coupling agent, a dispersing agent, a high-molecular compatilizer and the like are used for performing modification pretreatment on magnesium hydrate, so that the magnesium hydrate flame retardant has superior performance, the filling amount of the flame retardant in a substrate is up to 80-90 percent by weight, which is much higher than the adding amount of a flame retardant of the same type of products, the oxygen index of the product is remarkably increased in comparison to that of the same type of products, and the flame-retarding environmental protection performance is improved remarkably. An aluminum-plastic board core material prepared by adopting the method has the characteristics of freeness from halogen, low thermal value, low smoke, flame retardance, drop resistance, nontoxicity and freeness from pollution.

Description

technical field [0001] The invention relates to a sandwich layer material of an aluminum-plastic composite board, in particular to a class-A fireproof aluminum-plastic board core special material and a preparation method thereof. Background technique [0002] Aluminum-plastic composite panels are widely used in construction, decoration and other fields. Most of the core materials of aluminum-plastic composite panels are polyolefin (the most typical is polyethylene) core material or fire-resistant and flame-retardant polyolefin core material. The oxygen index of pure polyolefin core layer material is as low as about 17.5, and a rapid oxidation reaction occurs during the combustion process, which generates a large amount of heat, and the melting and dripping are very serious, which is easy to cause fire spread. At present, countries all over the world have increasingly stringent requirements for building safety, and fire performance is one of the most important indicators of s...
