Embodiment 1

[0016] Embodiment 1, PET / GF / CHP5: polyethylene terephthalate (PET) content is 65%; Cerium hypophosphite (CHP) content is 5%; Glass fiber (GF) content is 30%;

Embodiment 2

[0017] Embodiment 2, PET / GF / CHP10: polyethylene terephthalate (PET) content is 60%; Cerium hypophosphite (CHP) content is 10%; Glass fiber (GF) content is 30%;

Embodiment 3

[0018] Embodiment 3, PET / GF / CHP15: polyethylene terephthalate (PET) content is 55%; Cerium hypophosphite (CHP) content is 15%; Glass fiber (GF) content is 30%;

[0019] According to the thermal stability test of the raw material formula of above-mentioned three groups of mass percentages and the glass fiber reinforced polyethylene terephthalate (PET / GF) that does not add cerium hypophosphite (CHP) in nitrogen, its record contrast As shown in the following table:

[0020] Table 1 Formulation and thermogravimetric analysis data of PET / GF and PET / GF / CHP composites

[0021]

[0022] It can be seen from the above table that the thermal decomposition process of glass fiber reinforced polyethylene terephthalate (PET / GF) in nitrogen, at 397°C (T -3％ ) began to decompose, and the mass fraction of the residue was 39.9% at 700°C, mainly glass fibers and a small amount of searchlight. With the increase of CHP content, the actual decomposition temperature of PET / GF composites first in...

Abstract

The invention discloses a composite material and a manufacturing method of the composite material. Polyethylene glycol terephthalate of 55%-70%, ceroushypophosphate of 5%-15% and glass fibers of 30% are dried for 24 hours in a drying oven of 80 DEG C and then are mixed for 10 minutes in an internal mixer of 265 DEG C, wherein the rotation speed of the internal mixer in the mixing process is 100 rpm; the mixed sample is pressed to be in a sheet shape in a press vulcanizer of 270 DEG C, wherein the sheet is 3.2 mm thick. By means of the mode, the composite material and the manufacturing method are provided, and as the ceroushypophosphate is introduced into the raw materials of the composite material, not only is the thermal stability of the composite material kept, but also the carbon forming amount of the material in the high temperature area is increased. By the addition of the ceroushypophosphate, a large number of compact carbon residues are generated after burning to cover the surface of the glass fibers, thermal conductivity of the glass fibers is reduced, and the inflaming retarding capacity of the material is improved.

Description

technical field [0001] The invention relates to the field of organic composite materials, in particular to a composite material and a preparation method thereof. Background technique [0002] In recent years, the frequent occurrence of fires has brought great damage to human society and posed a great threat to human life, property and ecological environment. In order to reduce the impact of fire on human life, people have adopted various methods to protect materials from fire. Flame-retardant fire-resistant coatings are used because they provide fire protection for the substrate without affecting the physical and mechanical properties of the substrate itself. It has been highly concerned and valued by people. However, there are few mature products of flame-retardant and fire-resistant coatings, which are far from meeting the needs of society and people. Therefore, further research on transparent flame-retardant coatings and the development of new transparent flame-retardan...
