Abstract

Disclosed in the present invention are a polyamide composition, a preparation method therefor and the use thereof. The polyamide composition uses a polyamide resin as a matrix resin; and adding a hollow glass microbead masterbatch, a red phosphorus flame retardant and a reinforcement fiber enables the prepared polyamide composition to have the properties of low density, high toughness, flame retardance and high modulus. The hollow glass microbead masterbatch contains a first toughening agent and a first coupling agent. Applying an aromatic polyamide resin in cooperation with the red phosphorus flame retardant can satisfy relatively high flame retardance in the case of a relatively small dosage of the flame retardant, thereby preventing the problem of a density increase. Therefore, the prepared polyamide composition has good flame retardance and low density, and also has good toughness.

Abstract

Disclosed in the present invention are a flame-retardant PC/ABS composition with a fiber point effect, a preparation method therefor, and a use thereof. The flame-retardant PC/ABS composition with the fiber point effect according to the present invention comprises the following components: a polycarbonate, an ABS resin, a flame retardant, a high-temperature-resistant fiber point, and an anti-dripping agent, wherein the high-temperature-resistant fiber point is a regenerated cellulose fiber having a melting point of greater than or equal to 300ºC. In the flame-retardant PC/ABS composition with the fiber point effect according to the present invention, the high-temperature-resistant fiber point is used instead of a conventional carbon fiber- or glass fiber-reinforced conventional material, so that when the PC/ABS composition is combusted and contracted under heat, the anti-dripping agent can contract and gather at the high-temperature-resistant fiber point serving as a node to greatly slow down the perforation rate, and a carbon layer structure with a star-net-shaped dense distribution can be formed to isolate flame and heat, thus significantly improving flame-retardant properties. Moreover, the impact properties of the PC/ABS composition can also be better maintained, and the surface of the PC/ABS composition has a point-like aesthetic appearance effect similar to that of paint spraying.

Abstract

The present invention relates to the technical field of liquid crystal polymers (LCPs). Disclosed are an LCP film, a preparation method therefor and a use thereof. The LCP film of the present invention has a surface roughness from 350 nm to 850 nm, and a high-temperature storage modulus G' from 10,000 Pa to 25,000 Pa. By controlling the high-temperature storage modulus and the surface roughness of the LCP film, the LCP film has a certain deformation capability during copper-clad lamination. Meanwhile, a "rivet" effect that occurs when a low-roughness copper foil is laminated with the LCP film is maximized, thereby increasing the adhesion strength between the film and the copper foil. The LCP film has high copper-clad peel force, the peel strength is above 0.7 N/mm, meeting industry standard, and therefore, the LCP film can be applicable to the fields such as flexible printed circuit boards.
