| titleOfInvention | Weather resistant polyformaldehyde compound and preparation method thereof |
| abstract | The invention discloses a kind of weather resistant polyformaldehyde compound, it is mainly formed by the raw materials melt of following mass fraction: copolymerized methanal resin 91.5～97.5%, aggretion type UV absorbent 0.1～0.6%, aggretion type light stabilizer 0.1～1.0%, ultraviolet light screener 1.0～5.0%.This polyformaldehyde compound uses the UV absorbent of macromolecular, light stabilizer, add ultraviolet light screener simultaneously, the ultraviolet portion that can effectively absorb, shield, reflect in sunlight, ultraviolet is stoped to penetrate inside polyformaldehyde, effectively to stop the light degradation of polyformaldehyde, avoid its molecular chain rupture to form hydroxyl and carbonyl, thus improve the weatherability of polyformaldehyde compound.The present invention uses UV absorbent and light stabilizer to be macromole auxiliary agent, so ensureing to prevent while polyformaldehyde has excellent weather resistance the volatilization of auxiliary agent little molecule, migrating, extend polyformaldehyde compound service life in illumination and hygrothermal environment, improve the use value of polyformaldehyde, meet the needs at special dimension. |
