Problems solved by technology

The above types of flame-retardant ethylene-propylene rubber are mainly used for extruded and molded products. A large amount of metal compounds are added to the composition and there is no calendering processing aid, resulting in a significant decline in its process performance, and it is difficult to achieve calendering of thin products.

preparation example Construction

[0034] The preparation method of this flame-retardant ethylene-propylene rubber tarpaulin is one of the following, preparation method (A)

[0035] (1) Put each component of the flame-retardant ethylene-propylene rubber into the internal mixer according to the mass fraction, wherein:

[0036]

[0037]

[0038] Banbury at 80-110°C for 15-25 minutes, roll up and set aside;

[0039] (2) The rubber material after banbury mixing is re-mixed on the double-roller rubber mixer for 5-10 minutes, and rolled up and removed. The roller temperature of the calender is kept between 35°C and 50°C, start the calender, and place the re-milled film directly between the 1# and 2# rollers and between the 3# and 4# rollers of the four-roller calender. After the rubber material is completely covered on the surface of 2# and 3# rollers, the reinforcing fabric is placed flatly between the 2# and 3# rollers of the calender in the direction of glue feeding, and double-sided glued to form a rubber ...

Abstract

The invention belongs to the technical field of rubber materials, and relates to inflaming retarding ethylene propylene rubber tent cloth and a preparation method for the inflaming retarding ethylene propylene rubber tent cloth. The tent cloth adopts ethylene propylene rubber to serve as base rubber, the ethylene propylene rubber is matched with reinforcing packing, inorganic inflaming retarding packing, mineral inflaming retarding packing, a fire retardant, an anti-aging agent system, a vulcanization system and a rolling processing assistant agent to prepare the inflaming retarding ethylene propylene rubber which is in composition with reinforced fabric through a rolling machine, and the ethylene propylene rubber tent cloth is prepared after forming vulcanization. The oxygen index of the prepared rubber tent cloth can reach 30 above, 45-degree burning performance can reach a fire-retardant level, longitudinal strength>=3000N / 30mm, latitudinal strength>=3000N / 30mm, and fatigue performance is excellent. The tent cloth can achieve non-breakage after 20% tension for 50 thousand times and has good ozone resistance, climate resistance, hot air aging resistance, chemical medium resistance, water resistance and electricity insulation performance, and the temperature range for use is from-60 DEGC to 120 DEGC. The preparation method for the inflaming retarding ethylene propylene rubber tent cloth can be widely applied to rubber wind shields of low speed trains and low-speed-trains-to-be and rubber cloth for vessels.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and relates to a method for preparing a flame-retardant ethylene-propylene rubber tarpaulin. Background technique [0002] The hazards of fire pervade all areas of society. In the field of rail transportation, fires have not been spared, and once they happen, the losses will be huge. As the main material of the rubber windshield at the end of the train, the rubber shed cloth is a necessary part of the sealing, heat insulation and sound insulation of modern rail trains. Its combustion performance has a direct impact on the consequences of fires, especially for relatively closed high-speed operating environments. Therefore, the development of environmentally friendly ultra-low smoke, low toxicity, halogen-free flame-retardant ethylene-propylene rubber shed cloth is of great significance for reducing the probability of train fires and reducing casualties and property equipment losses cause...
