After the putty is coated, the whole vehicle is required to be polished by using sand paper, the middle painting can be sprayed after the putty layer is polished to be smooth, a large amount of putty powder can be recovered by a dust collecting device, and the recovered putty powder of each vehicle is about 15 kg. Because no mature recycling technology exists, the recycled putty powder is difficult to degrade and can only be treated as dangerous waste, thereby polluting the environment. The treatment cost is required for hazardous waste treatment, each kilogram of putty powder needs 5 yuan, 800 vehicles are repaired in factories every year, 12t of putty powder is generated in an accumulated mode, the treatment cost is about 6 ten thousand yuan per year, the treatment cost is high, and the treatment difficulty is high.
Disclosure of Invention
In order to solve the technical problems that the unsaturated polyester putty polishing powder can only be treated as a hazardous waste at present, pollutes the environment, has higher treatment cost and has higher treatment difficulty, the invention provides unsaturated polyester putty based on the unsaturated polyester putty recovery polishing powder.
The technical scheme adopted by the invention for solving the technical problem is as follows:
the unsaturated polyester putty is characterized by comprising the following components in parts by mass:

The two-component unsaturated polyester putty powder after the car body is polished is collected in a centralized way and is stored uniformly by using a container or a cloth bag; and sieving the putty powder by using a 800-mesh sieve, collecting the putty powder with the particle size of below 800 meshes, and not utilizing the rest putty powder with larger particles. The putty powder with the particle size of below 800 meshes is used as a filler, and formula development is carried out according to the technical requirements of the table I, wherein the formula design principle is as follows: 1. adjusting the working life: the use level of the accelerator is reduced when the working life is short; when the pot life is long, the dosage of the accelerator is increased. 2. Blade coating property adjustment: when the drawability is poor, the amount of silica used is increased. 3. Adjusting the sanding property: when the sanding property is poor, the using amount of the talcum powder is increased or the using amount of the resin is reduced. 4. And (3) flexibility adjustment: when the flexibility is poor, the resin dosage is increased or the talcum powder dosage is reduced.
