Effect of plasticizer dibutyl phthalate on the thermal
This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope. It was found that the fibers in NC-D are more closely aligned than those in NC-P

Experimental study on the fire characteristics of typical
Samples. In the present study, four kinds of NC samples were selected to examine their fire hazard characteristics. For the convenience of presentation, they were labeled as NC-P (pure NC, C 12 H 16 N 4 O 18), NC-D (NC contains 19.5 mass% plasticizer dibutyl phthalate, C 16 H 22 O 4), NC-E (NC contains 30% humectant ethanol, C 2 H 6 O) and NC-I (NC contains 30% humectant isopropanol, C 3 H 8 O).

- Does plasticizer dibutyl phthalate affect thermal decomposition of nitrocellulose?
- This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope.
- How does plasticizer DBP affect the microscopic structure and thermal decomposition mechanism?
- The effects of DBP on the microscopic structure, kinetic characteristics, and thermal decomposition mechanism of NC were investigated using a range of apparatus. The main findings can be summarized as follows: 1. Plasticizer DBP makes NC fibers present an adhesion state. The distance between fibers in NC-D is much lower than that in NC-P.
- What is the best plasticizer for PVC?
- Dibutyl phthalate is the most commonly used plasticizer for PVC, which can make the products have good softness. Dibutyl phthalate is an excellent plasticizer for nitrocellulose with strong gelation ability. It is used in nitrocellulose coatings and has a good softening effect.
