Toxicity and flammability of petroleum resin raw materials

Most of the raw materials used in the process of applying petroleum resin have certain toxicity, and they are more likely to cause explosion and fire.

In the application process, the hazards of various raw materials vary with the types of materials. The following is only a brief introduction:

1. Petroleum resin: Petroleum resin itself is non-toxic.

2. Curing agent: Among the materials used in the process of manufacturing petroleum resin, the curing agent is more toxic, and various curing agents are distinguished according to their toxicity. Class curing agents and various new modified curing agents are less toxic.

3. Refining plasticizer: In the plastic picking agent used in the manufacture of petroleum resin, the active plasticizer (such as polysulfide rubber) will evaporate gas, so it has a certain degree of toxicity, but it is less toxic.

4. Thinner: In the thinner used, acetone, which is more volatile, is sometimes used.

Long-term exposure to acetone will cause skin irritation. Long-term inhalation of acetone vapor will have a certain anesthetic effect on the human respiratory tract, esophagus and other organs.

5. Filler: general fillers are not toxic, but some powdered fillers (such as iron powder, aluminum powder, quartz powder, etc.) and some fibrous fillers (such as glass fiber, etc.) dust, inhaled in the respiratory organs, easy to cause Occupational diseases such as silicosis.

6. Others: other materials such as release agent, cleaning agent, etc., except for individual materials (such as acetone in cleaning agent and benzene in release agent, etc.), generally have something to change or only have very light toxicity , So as long as it is carried out in accordance with the production operation rules during production, it will not cause any harm.
