Many, stick to as the oil smoke in kitchen on face, had a strong impact on the light transmittance of chamber facility, had a strong impact on crop photosynthesis
Process.Anti-Organic Pollution is more difficult to than dust-proof.
Summary of the invention
For the deficiencies in the prior art, the present invention provides the preparation method of a kind of photocatalyst-type anti-soil greenhouse films, the present invention
Add catalysis material by the outer layer at multi-layer polyolefin inflation film, be allowed to possess and decompose having of adhering on greenhouse films surface
Machine thing, to reach to improve effect of greenhouse cleaning light transmittance.
Summary of the invention:
The poroid powder body material of present invention micron order joins in Nano titanium dioxide colloidal sol, is stirred, allows
Nano titanium oxide in colloidal sol is scattered in micron-sized powder hole.It is added into again in anti-soil applying liquid.Liquid is coated
To the dust-proof pollution layer of greenhouse films, the titanium dioxide being in top layer is shown in generation void effect after light, face dustiness is produced light and urges
Organic substance is decomposed by change effect, and not injures inorganic particle.Micron-sized powder has scattering process to sunlight, makes the light back side
Nano titanium dioxide photocatalysis declines, slow down the decomposition to coating and film base material.Both there is decomposition film
Face Organic substance is avoided polluting, the most effectively protection base material and the effect of coating.
