A low-smoke halogen-free flame-retardant ABS material for edge banding and its preparation method

Abstract

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. The low-smoke, halogen-free, flame-retardant ABS material for edge banding includes the following raw materials: ABS resin, halogen-free flame-retardant filler, smoke suppressant, surface modifier and lubricant; wherein, the mesh number of the halogen-free flame-retardant filler is 7500-10000 mesh. The ABS material of the present invention increases the compatibility between the halogen-free flame-retardant filler and the smoke suppressant and the ABS resin, which not only improves the flame-retardant and smoke-suppressing effect of the ABS material, but also reinforces the ABS material, avoiding the The mechanical properties of the ABS material are reduced due to excessive filling of the smoke suppressant, resulting in the embrittlement of the ABS material, thereby avoiding the brittleness of the edge banding produced by the ABS material and reducing the probability of chipping of the edge banding.

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.
