Comparative example 1:
preparation of a common coating: heating, mixing and stirring the polypropylene and the auxiliary agent uniformly, and curing by using a curing agent to obtain the common coating.
Comparative example 2:
the formulation of comparative example 2 was the same as that of example 1, and the weatherable composite flame retardant coating was prepared by a method different from that of example 1 only in that the preparation of step (1) was not performed, and the remaining preparation steps were the same as those of example 1.
Comparative example 3:
the formulation composition of the ratio 3 is the same as that of the example 1, and the preparation method of the weather-resistant composite flame-retardant coating is different from that of the example 1 only in that the preparation of the step (2) is not carried out, and the rest of the preparation steps are the same as those of the example 1.
Test example 1
The coatings prepared in example 1, comparative example 1 and comparative example 2 were applied to cotton fabric, respectively, and their burning properties were measured to observe LOI values and burning ratings as follows:
(the larger the LOI value, the better the flame retardancy)
| LOI | Grade of combustion | |
| Example 1 | 30％ | Flame retardant |
| Comparative example 1 | 15％ | Inflammable |
| Comparative example 2 | 25％ | Flammable material |
It can be seen from the above data that the flame retardant effect of example 1 is the best, because the hydrochloric acid modified sepiolite can promote the carbonization of the system, promote the intumescent flame retardant to form a stable carbonized substance at high temperature, quickly generate a continuous protective carbon layer, and under the combined action of the hydrochloric acid modified sepiolite and the maleic anhydride grafted ethylene propylene diene monomer, the surface of the residual carbon can be more uniform and compact, the formed porous carbon layer plays a flame retardant role in a coacervate phase, and the porous carbon layer serves as the barrier tissue for heat transfer and oxygen diffusion, thereby preventing the generation of volatile combustible components, effectively preventing and delaying the degradation of the polymer, achieving the purpose of interrupting the combustion of the polymer, reducing the release of combustible gas and smoke, and preventing the flame propagation.
Test example 2
The three coatings prepared in example 1, comparative example 1 and comparative example 3 were controlled to have a thickness of 0.1mm, respectively, and the impact resistance of the coatings was tested according to GB/T1732 and recorded as follows:
(the higher the height, the better the impact resistance)
| Height (cm) | |
| Example 1 | 82 |
| Comparative example 1 | 31 |
| Comparative example 3 | 56 |
It can be seen from the above data that the impact strength of example 1 is the highest, which indicates that the impact resistance is the best, because dicumyl peroxide can promote the increase of the crosslinking degree of the maleic anhydride grafted ethylene propylene diene monomer rubber and the polypropylene, so that the structure of the maleic anhydride grafted ethylene propylene diene monomer rubber and the polypropylene is more compact, and dicumyl peroxide enables the hydrochloric acid modified sepiolite, the maleic anhydride grafted ethylene propylene diene monomer rubber and the polypropylene to be more densely crosslinked, so that the density of the network structure of the sepiolite is enhanced, excellent wear resistance is achieved, the entanglement and crosslinking of the hydrochloric acid modified sepiolite on the polypropylene molecular chain can be enhanced, and part of external impact energy can be absorbed, so that the impact strength is improved.
