Low-smoke halogen-free flame-retardant ABS material for edge sealing strips, and preparation method thereof

Abstract

The invention relates to the technical field of edge sealing strip material modification, particularly to a low-smoke halogen-free flame-retardant ABS material for edge sealing strips, and a preparation method thereof, wherein the low-smoke halogen-free flame-retardant ABS material comprises the following materials: an ABS resin, a halogen-free flame-retardant filler, a smoke suppressant, a surface modifier and a lubricant, wherein the halogen-free flame-retardant filler has a particle size of 7500-10000 mesh. According to the present invention, the ABS material can increase the compatibilityamong the halogen-free flame-retardant filler, the smoke suppressant and the ABS resin, such that the flame-retardant smoke suppressing effect of the ABS material is increased, the ABS material is strengthened, and the condition that the excessive filling with the halogen-free flame-retardant filler and the smoke suppressant can reduce the mechanical property of the ABS material so as to cause theABS material embrittlement can be avoided so as to avoid the embrittlement of the edge sealing strip prepared from the ABS material and reduce the probability of the corner chipping of the edge sealing strip.

Description

technical field [0001] The invention relates to the technical field of modification of edge banding materials, in particular to a low-smoke, halogen-free flame-retardant ABS material for edge banding and a preparation method thereof. Background technique [0002] It is understood that when a fire breaks out, it is the toxic gas and highly toxic smoke released when the material burns that causes harm to the human body. The strong and diffuse smoke makes the victim unable to distinguish the direction, thus prolonging the stay time at the fire scene Therefore, in order to avoid and reduce the secondary damage caused by fire and fire, low-smoke halogen-free flame-retardant home decoration materials are more and more popular. [0003] The edge bands commonly used in home decoration are generally divided into log edge bands, PVC edge bands and ABS edge bands. Although the log edge banding is simple to make, it is expensive, especially with the gradual improvement of people's awar...

AI Technical Summary

Problems solved by technology

[0004] As an effective inorganic flame retardant for low-smoke, halogen-free flame-retardant ABS materials, such as magnesium hydroxide and aluminum hydroxide, a large amount of filling is required to achieve the expected flame-retardant effect, which greatly affects the physical and mechanical properties of ABS, especially the impact The strength drops a lot, and even turns into a brittle material, which causes the edge banding to collapse when it is used for edge banding.
