Benefits of technology

The technical effect described by this patented technology compared to previous methods involves improved fire resistance properties for polyphenylene oxide (PPO) fibers used in fiber reinforced plastic materials or other composites made from PBO polymeric resin matrices. This results in better performance at high temperatures over time without losing its strength due to decomposition caused by heat exposure during use.

Problems solved by technology

This patented technical problem addressed in this patent relates to finding ways to improve the performance of fiberglass products without relying solely upon any existing methods like combustion treatment technology. Specifically, there needs to be some way to achieve better flames retarding property while reducing environmental impact during manufacturing processes.

[0039] Flame Retardant Properties of Cotton Fabrics Without Flame Retardant Treatment

[0040] The test results of the flame retardant properties of pure cotton fabrics show that the limiting oxygen index (LOI) of pure cotton fabrics is 15.11, the vertical burning performance results show that the afterburning time is 30.27s, the smoldering time is 10.34s, and the damage length is 30cm.

Embodiment 2

[0042] Flame retardant properties of cotton fabrics treated with epoxy-based POSS / APP composite flame retardant finishing agent (3:1)

[0043] Preparation of epoxy-based POSS / APP composite flame-retardant finishing agent: After emulsifying an appropriate amount of epoxy-based POSS evenly, add APP according to the mass ratio of epoxy-based POSS and APP to 3:1, heat to dissolve at 90°C and stir evenly to prepare Into a flame retardant finishing agent.

[0044] Flame retardant finishing of cotton fabrics: Cotton fabric → double dipping and double rolling (residue rate 90%) → pre-baking (100°C, 3min) → baking (150°C, 3min).

[0045] The limiting oxygen index of the cotton fabric after finishing is 34.11, the vertical burning performance is 18.54s afterburning time, smoldering time is 0s, and the damage length is 30cm.

Embodiment 3

[0047] Flame-retardant properties of cotton fabrics treated with epoxy-based POSS / APP composite flame-retardant finishing agent (3:2)

[0048] Preparation of epoxy-based POSS / APP composite flame-retardant finishing agent: After emulsifying an appropriate amount of epoxy-based POSS evenly, add APP according to the mass ratio of epoxy-based POSS and APP to 3:2, heat to dissolve at 90°C and stir evenly to prepare Into a flame retardant finishing agent.

[0049] Flame retardant finishing of cotton fabrics: Cotton fabric → double dipping and double rolling (residue rate 90%) → pre-baking (100°C, 3min) → baking (150°C, 3min).

[0050] The limiting oxygen index of the cotton fabric after finishing is 40.56, the vertical burning performance is 0s afterburning time, smoldering burning time is 0s, and the damage length is 5.0cm.

Abstract

The invention relates to a preparation method and application of an epoxy-based POSS (polyhedral oligomeric silsesquioxane)/ammonium polyphosphate composite flame retardant; after being emulsified, epoxy-based POSS is mixed with ammonium polyphosphate to obtain a composite flame-retardant finishing agent, cotton fabric is subjected to roll-baking flame-retardant finishing with the composite flame-retardant finishing agent, flame retardancy of the cotton fabric is greatly improved, and the cotton fabric is imparted certain water repellency and wrinkle resistance. Compared with the prior art, the preparation method and application have the advantages that epoxy groups capable of reacting with cotton fabric may be crosslinked with the cotton fabric, the bonding problem of the POSS flame retardant and the cotton fabric is solved, the flame-retardant finishing provides higher binding firmness than coating finishing and the flame retardant is more convenient to apply than coatings.
