Sealant is a kind of sealing material which is deformed with the shape of sealing surface and is not easy to flow. It is an adhesive used to fill the gap between configurations and act as a sealant. It has the functions of leak proof, waterproof, vibration proof, sound insulation and heat insulation. It can be roughly divided into silicone, polyurethane, polysulfide, acrylic acid, butyl, asphalt and oil resin modified products. Sealants for construction mostly belong to synthetic adhesives. The main body of sealants is polymer. Their properties can be divided into three categories: bulk properties, process properties and use properties.

The bulk properties depend on the chemical properties and physical structure of the main polymer of sealant, which can be accurately measured repeatedly. Technological properties refer to the properties of sealants in the manufacturing process. It is self-evident that the use property mainly refers to the comprehensive performance of sealant from the formation of cementation process to the formation of cemented joints, which depends on the functional requirements of sealant for building joints. Whether for building envelope or interior decoration; whether for window structure or other forms of envelope and decoration structure, they can be regarded as unit composition, then there will be joints between each unit, the vast majority of buildings need to be sealed and filled with sealant.

In the process of home decoration, the children in the family usually worry about the environmental protection of materials, especially for pregnant mothers. What are the environmentally friendly materials on the market? What kind of sealants are the most used? Do sealants have an impact on babies?

Sealant is a kind of adhesive used to fill the gap between configurations and play a sealing role. It is a kind of sealing material that can deform with the shape of sealing surface and is not easy to flow. Usually asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber and other dry or non-dry viscous substances are used as binders, with talcum powder, clay, carbon black, titanium dioxide and asbestos inert fillers, followed by plasticizers, solvents, curing agents, accelerators and so on. Because there are also some solvents and curing agents, so it contains some chemical elements, chemical elements are known to be harmful to human body, can make human cells protein, the retina has greater damage to the optic bulb, olfactory abnormalities, irritation allergies lead to abnormal lung, liver and immune function. It has been listed as a suspected carcinogen by the International Association for Cancer Research.

Benzene is absorbed and poisoned through respiratory tract and skin, which affects nervous system, liver, kidney and immune system. Benzene is a causative factor of leukemia and a carcinogen, which may weaken human reproductive capacity. Ammonia can irritate and damage skin, respiratory tract and eyes, etc. That's true for adults. How much resistance can you imagine for a pregnant baby?
