Abstract
The invention relates to a low optical distortion PVB film formula. The low optical distortion PVB film formula comprises the following components in parts by weight: 100 parts of PVB resin, 25-40 parts of a plasticiser, 0.5-3 parts of an anti-oxidant, 0.1-1.5 parts of an ultraviolet light absorber, 0.2-3.5 parts of a modifying agent, and 0.05-2.7 parts of a chain extender. Compared with a common PVB film formula, the formula provided by the invention can remarkably improve mechanical indexes such as tensile strength and anti-impact performance of a PVB film, and can improve the aging resistance, yellowing resistance performance, as well as the stability and the uniformity of molecular weight of the PVB film, so that the possibility of optical distortion caused by the uneven performance of the PVB film is remarkably reduced.
Description
Technical field
The present invention relates to a kind of low light distortion PVB film formula, belong to thermoplastic macromolecule material technical field.
Background technology
Along with expanding economy, the Application Areas of laminated glass is more and more wider, in polyvinyl butyral acetal (PVB) resin, adding softening agent, to be processed into film for making laminated glass be well-known, namely at high temperature under high pressure, PVB film is as this material of bonding, sprawl at glass surface, the process such as infiltration, layer glass compound is as a whole the most at last.At present, main employing adds softening agent to prepare PVB film in polyvinyl butyral acetal, such as patent CN1284911, CN1518494 individually disclose a kind of film of the plasticizer-containing be made up of the polyvinyl alcohol of part acetalation, CN1484671 discloses a kind of polyvinyl butyral acetal of plasticizer-containing, Preparation Method And The Use, is particularly useful for the purposes of the shatter proof glass film producing laminated glass.
Light distortion Producing reason is that glass surface is uneven or indicative of local optical is uneven, the light passed through is produced and departs from, thus image is out of shape.As light distortion degree is comparatively large, then easily make the eyes of officer produce tired, cause the generation of traffic accident.Domestic PVB glued membrane ubiquity tensile strength is low compared with imported product, shock resistance is poor, and ageing-resistant performance, yellowing resistance such as to differ from the problem, make its light distortion poor-performing.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of low light distortion PVB film formula, to overcome the shortcoming of the light distortion poor-performing occurred in prior art, this PVB film formula comprises the component of following mass parts:
PVB resin: 100 parts;
Softening agent: 25-40 part;
Oxidation inhibitor: 0.5-3 part;
UV light absorber: 0.1-1.5 part;
Properties-correcting agent: 0.2-3.5 part;
Chainextender: 0.05-2.7 part.
In a preferred embodiment of the invention, described softening agent is preferably 3GO softening agent.
In a preferred embodiment of the invention, described oxidation inhibitor is preferably antioxidant 1010.
In a preferred embodiment of the invention, described UV light absorber is preferably UV light absorber 326.
In a preferred embodiment of the invention, described properties-correcting agent is preferably ADD3310.
In a preferred embodiment of the invention, described chainextender is preferably chainextender ADR.
Described ADD3310 and chainextender ADR all obtains by commercially available purchase, originates from Basf China Co., Ltd.Thermoplastic engineering plastic resin can be produced degraded chain rupture and become shorter chain to reconnect by described ADD3310 in high temperature working processes because of hydrolysis, thus improves molecular weight.It is used to reduce in the course of processing performance generating low-molecular(weight)polymer and lifting recycling material because of degraded.
In a preferred embodiment of the invention, this low light distortion PVB film formula, comprises the component of following mass parts:
PVB resin: 100 parts;
3GO softening agent: 30 parts;
Antioxidant 1010: 1 part;
UV light absorber 326:1 part;
ADD3310:1.5 part
Chainextender ADR:1.0 part.
The present invention studies for a long period of time to the component of film and proportioning, the formula obtained is compared with common PVB film formula, the mechanical index such as the tensile strength of PVB film, shock resistance can be significantly improved, and the stability of ageing-resistant performance, yellowing resistance energy and molecular weight and homogeneity, significantly reduce the uneven light distortion performance caused of PVB film performance.
Embodiment
Below by embodiment, the present invention will be further described.
Embodiment
Production unit is sharp magnificent 95 twin screw production lines, and low light distortion PVB film formula is as shown in table 1.
Table 1
Performance test is carried out to the film of three kinds of formulas that above-mentioned formula obtains, the results are shown in table 2.
Table 2
Further, by client's service condition, the film that new formula is produced shows and is better than the obtained automotive safety glass performance of common film, is especially significantly improved in light distortion performance.
Above embodiment display and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; instead of limit the scope of the invention by any way; without departing from the scope of the invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed scope.
