What are the harmful effects of epoxy resins on the body?

1.Epoxy floor paint is a petrochemical product, which is more or less toxic.

2.Epoxy floor paint solvents are harmful to human health, such as xylene, Tianna water, and the VOC content of these substances is high, which is one of the main culprits of haze weather.

3.The curing agent of epoxy floor paint that is not well handled and unqualified is toxic and harmful to the human body.

4.The pigment of epoxy floor paint that is not well handled and unqualified is a heavy metal element and is harmful to the human body.

Harmful causes: resin we are most familiar with resin spectacle lens, its benefits are relatively light, high wear resistance, resin is non-toxic, so resin spectacle lenses are not any toxicity, but epoxy resin does have a certain degree of harm, this is because epoxy resin is added to some toxic substances, these toxic substances are generally volatile and flammable, and have certain harm to the body. It is flammable, thus causing harm to the environment and the human body. Therefore, we must be cautious when using epoxy resin products to avoid causing harm to the human body.

Epoxy resin and epoxy resin adhesive itself is non-toxic, but due to the addition of solvents and other toxic substances in the preparation process, many epoxy resins are therefore toxic.

At present, the vast majority of epoxy resin coatings are solvent-based coatings, which contain a large number of volatile organic compounds (VOCs), which are toxic and flammable, thus causing harm to the environment and the human body.

VOC is the English abbreviation for volatile organic compounds. When the VOC concentration in the environment exceeds a certain level, people will feel headache, nausea, vomiting, and weakness in the limbs for a short period of time.

If you do not leave the scene in time, you will feel that the above symptoms will be aggravated, and in severe cases, you will have convulsions, coma, and memory loss. VOCs harm people's liver, kidneys, brain, and nervous system, and can even cause blood problems in the human body, and other serious diseases such as leukemia.

VOC in the paint is a volatile substance, in which formaldehyde, benzene, xylene and other harmful substances will slowly volatilize, its infringement process is slow, and it is not easy to attract people's attention, and when it is found that the body has a serious discomfort, the degree of harmful substances to the human body has been quite serious.

Epoxy resin has low toxicity before curing, harmful to the human body, and non-toxic and environmentally friendly after curing.

Epoxy glue.

There are two combinations, among them.

Epoxy resin. Low-toxicity curing agent.

There are two kinds of poison, highly toxic and low-toxic.

But if after contacting **, rinse with water in time for about 15 minutes, it doesn't matter.

Epoxy resin glue is harmless to the human body.

Epoxy resin adhesive is non-physiological, harmless to the human body, and can be formulated with low odor and non-toxic environmentally friendly adhesive. The toughness is not good, the brittleness is large, and the toughness modification is usually required.

Epoxy resin adhesive generally refers to the adhesive made with epoxy resin as the main body, and epoxy resin adhesive should generally also include epoxy resin curing agent, otherwise the glue will not cure.

Epoxy resin itself is non-toxic.

Epoxy resin: Epoxy resin is also known as artificial resin, artificial resin, resin glue, etc. It is an important class of thermosetting plastics, which are widely used in adhesives, coatings and other uses.

Epoxy resin is an organic polymer compound that contains two or more epoxy groups in the molecule, and their relative molecular weight is not high except for a few.

The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can cross-link with various types of curing agents to form insoluble, non-meltable polymers with a three-way network structure.

In-situ epoxidation.

The in-situ epoxidation method refers to the epoxidation reaction of the synthesis of organic peroxytic acid and olefins in the same system, so that the generated organic peroxytic acid reacts with olefins immediately, and there is no process of peroxyacid enrichment. For example, acetic acid is mixed with an alkene-containing compound, and then hydrogen peroxide is added to the system, and the acetic acid reacts with hydrogen peroxide to form peracetic acid and an alkene-containing substrate that is immediately epoxidized to obtain the product. This method is characterized by simple process, low equipment investment, and no safety hazards caused by peroxide enrichment.

Separation epoxidation method.

The separation epoxidation method is different from the in-situ epoxidation method, which refers to the synthesis of organic peroxyacids and the separation of the epoxidation process. This method is characterized by the separation of the two processes, which is conducive to the detection and control of the two processes separately, so it is suitable for industrial large-scale production. UCC Corporation and Shanghai Petrochemical Plant both use this method to produce epoxy resins.
