White carbon blackApplication of nano silica in plastics

Silica can be made by adding gas phase silica to polyethylene by a special method

The polyethylene composites with high wear resistance and high hardness are prepared by dispersing uniformly in the matrix. adopt

Graft polymerization was used to modify the surface of vapor phase silicon dioxide

Chains to effectively block nanoparticles, reducing their agglomeration, and then fill polypropylene with them,

Nano Si02 / PP composites with excellent comprehensive properties were prepared by blending technology.

At low addition, the toughness of polypropylene can be increased by about two times. If it's in a composite system

By adding an appropriate amount of elastomer, polypropylene can be polymerized while maintaining its rigidity and tensile strength

The notch impact resistance of propylene increased by about 3 times, the analysis of silicon dioxide and elastomer

It can act synergistically to strengthen and toughen polypropylene. The dioxide is oxidized by blending

Nano Si02 / PMMA plastics prepared by adding silicon to PMMA can significantly improve the material

Performance. When 4% is added, the notched impact strength of PMMA can be increased by more than 80%.

And the prepared composite material has good optical transparency.

In the blending system of plastics and other polymers. Silica can be added to improve the compatibility of the two phases.

Such as Ps and PP blending system, adding gas phase silica modified by or methyl chlorine, can be

The interfacial tension is reduced, the temperature of turbidity point is decreased, and the compatibility of the two is improved.

Adding vapor silica to epoxy resin can obviously improve its brittleness and overcome the elastomer

The defects caused by toughening reduce the rigidity and strength of the material to achieve the purpose of strengthening and toughening. Tang Tian

When the dosage is 3wt %, the impact strength and tensile strength of the composite system can be increased by 40%

21%. If the nano silica is modified by coupling agent, the impact toughness can be made

Increased by 124%, tensile property increased by 30%, in addition, also makes the product hardness, wear resistance,

Temperature resistance and insulation properties are improved.

Thixotropic polyester and gelcoat resin applications in thixotropic polyester resin, the use of almost

All are silica, on the one hand, it can make the product thickness more uniform, shrinking, more

Plus meet the requirements of the design; On the other hand, due to the thixotropy of the resin, r resin is reduced

The flow and drip reduces the waste of resin. The production environment is protected. At 43.5%

In the unsaturated polyester of phthalic acid type, 2% silica can be added to 4.8

This thixotropic index has met the domestic construction technology of gelcoat resin.Cano (Guangzhou) new materials
