Problems solved by technology

Chinese patent 94115901 discloses a formula and production method of "normal temperature quick-drying high-grade polymeric putty". The putty is mainly composed of mixed unsaturated resin, and has the characteristics of putty putty, fast drying, strong adhesion, flexibility and sandability. , good brushing properties, etc., but the resin used in this patent is an unsaturated polyester resin commonly used in putty, and the heat-resistant temperature is usually below 150°C. At the same time, the putty has no flame retardant performance, so the putty The heat resistance and flame retardancy cannot meet the special and strict requirements of subway vehicles and other high-temperature places, such as front cars, axles, smoke (steam) channels, etc.

preparation example Construction

[0046] B. The preparation of the curing agent is to put the four kinds of raw materials (18)-(21) into the low-speed disperser. After dispersion, the output rough curing agent is produced. The rough curing agent is ground to produce the finished curing agent. tube packaging, ready to use;

[0047] C. Preparation of flame retardant putty. When in use, mix the main agent of the finished product and the finished curing agent in a weight ratio of 100:3-5 to obtain the flame retardant putty of the present invention.

[0048] The flame retardant putty prepared by the method of the present invention.

Embodiment 1

[0051] For the production of the main agent, put 3 parts of nano-montmorillonite as a heat-resistant enhancer and 10 parts of active diluent into a high-speed disperser, and after fully dispersed (5 minutes), a coarse suspension is produced and pumped into the grinder Medium grinding to produce a nano-montmorillonite suspension, then put it into the disperser and add other raw materials three times: the first time: add 70 parts of heat-resistant unsaturated polyester resin, 30 parts of silicone resin, with an interval of 5 minutes, the second time Add 4 parts of anti-settling agent for the second time, with an interval of 5 minutes, add 3 parts of special filler, 5 parts of putty performance modifier, 1 part of flame retardant, 5 parts of low shrinkage additive, and 0.1 part of stabilizer for the third time, as a promotion 0.5 part of dimethyl aniline as agent, 0.5 part of dispersant, 4 parts of titanium dioxide, 5 parts of hollow glass microspheres, 3 parts of drier, 0.5 part ...

Abstract

The invention discloses flame-retarding lacquer putty and a preparation method thereof, and aims to provide air-dried organic silicon-modified unsaturated flame-retarding lacquer putty which has good comprehensive performance, long-term use at the temperature of below 250 DEG C and self-drying property at normal temperature to meet special requirements of subway vehicles and casthouse vehicles, wheel shafts, smoke (steam) passages and the like in other high temperature places. The air-dried organic silicon-modified unsaturated flame-retarding lacquer putty is characterized by being prepared by mixing raw material nano-montmorillonite not containing a halogen element compound, reactive diluent, a heat-resistant unsaturated polyester resin, an organic silicon resin, a special filler, a flame retardant, a low shrinkage additive, a stabilizer, dimethylaniline, a dispersant, titanium dioxide, hollow glass micro-beads, a drier, molybdenum disulfide, talcum powder, ketone peroxide, a curing agent filler, quinacridone bluish red and polyvinylpyrrolidone in a certain proportion, dispersing and grinding the mixture to prepare a main agent and a curing agent, and mixing the main agent with the curing agent. The flame-retarding lacquer putty is mainly used as a bottom coating material for subway vehicles.

Description

technical field [0001] The invention relates to a flame-retardant putty and a preparation method thereof. Background technique [0002] Flame retardant putty usually refers to the primer coating material for metal surface embedding materials, especially a normal temperature drying and air drying type silicone modified unsaturated flame retardant putty. There are generally two types of filling materials for metal surfaces: one is water-based putty, and the other is (natural or synthetic) resin putty. Chinese patent CN86101069 discloses a formula called "cross-linked emulsion baking putty" and its production method. The putty uses water instead of organic solvents. It is non-flammable, non-toxic and harmless, and does not pollute the environment. However, the putty manufactured by this patent must be dried at about 110°C for 50 minutes; such drying conditions greatly limit the use of its putty , due to large-scale equipment and accessories that are inconvenient to move (remo...
