Is silicone glue poisonous? What are the ingredients? Principle analysis and mechanism introduction of silica gel glue
Dec 27,2022 Hanast
Silica gel is a new type of environment-friendly non-toxic material. The silicone rubber adhesive, i.e. silicone glue, is irreplaceable in silicone products. Whether silicone glue is toxic or not, we have to analyze it from the principle, action mechanism of silicone glue and the criteria for judging the toxicity of adhesive.
Analysis of the principle of silica gel glue
Silica gel, also known as silicic acid gel, is a highly active adsorption material and an amorphous substance. Silicone consists of silicone based adhesive, silicon dioxide, calcium carbonate, curing agent, etc. The main component is silicon dioxide, which is chemically stable and does not burn. Silica gel can be said to play a more and more important role in our life, but in our daily use of silica gel, we are faced with the adhesion of silica gel and silica gel, silica gel and plastic products, silica gel and metal and other materials, which requires us to have the adhesive, that is, silica gel glue.
Introduction to the action mechanism of silica gel glue
Silica gel glue is a kind of highly active adsorption material, with organic silicon macromolecule compound as the main component, which belongs to amorphous substance. Silica gel glue is a kind of adhesive used for bonding silica gel and silica gel, silica gel and similar plastics in silicone rubber. It is cured by contacting the water molecules on the surface of the bonded or sealed objects or the water molecules in the air. It is insoluble in water and any solvent, non-toxic and tasteless, with stable chemical properties, and does not react with any substance except strong base and hydrofluoric acid. Various types of silica gel glues form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel glue determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.
What is the judgment standard for the toxicity of silicone glue?
During the working process of the adhesive, some benzene substances volatilize, resulting in poor breathing or skin allergy. This is a poisonous standard, which is unacceptable to all users. The silicone glue is made of new raw materials, which is environmentally friendly and healthy and does not contain any toxic substances.
It has been proved by authoritative tests that silicone glue is a solvent-free product, does not contain any volatile substances, will not affect human health and will not pollute the environment.
When silica gel glue is solidified, formaldehyde and benzene will not volatilize. All raw materials have passed the SGS environmental protection test and are food grade materials. In short, the raw materials of silicone glue have reached the level that can be imported. How can it contain toxic substances?
If solvent silicone rubber adhesive is selected, it is important that it has passed advanced medical level testing and SGS environmental protection testing, and it can also be used. In order to avoid potential safety hazards, it is recommended to choose paste adhesive, which has no volatile matter and no worries in the future.
Silica gel adhesive is not a dangerous product, but a chemical, which may cause many users worry; For all users, choose a healthy and environment-friendly silicone adhesive, which will not harm the body of the staff and will not pollute the environment.
