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 is well-known for making laminated glass, under High Temperature High Pressure, PVB film is as this material of bonding, sprawl at glass surface, the process such as infiltration, layer glass is compound as a whole the most at last.At present, mainly adopt and in polyvinyl butyral acetal, add softening agent to prepare PVB film, such as patent CN1284911, CN1518494 disclose respectively a kind of film of the plasticizer-containing of being 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 producing the purposes of film for the shatter proof glass of laminated glass.
The reason that light distortion produces is that glass surface is uneven or indicative of local optical is inhomogeneous, the light generation of passing through is departed from, thereby make image distortion.As larger in light distortion degree, easily make officer's eyes produce fatigue, 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 the problem such as can differ from, and makes 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 occurring 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 can obtain by commercially available purchase, originate from Basf China Co., Ltd.Described ADD3310 can become shorter chain to reconnect because hydrolysis produces degraded chain rupture thermoplastic engineering plastic resin in high temperature process process, thereby improves molecular weight.It is used in the course of processing to reduce and generates low-molecular(weight)polymer and promote the performance of recycling material because of degraded.
In a preferred embodiment of the invention, this low light distortion PVB film is filled a prescription, and 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.
Component and the proportioning of the present invention to film studies for a long period of time, the formula obtaining is compared with common PVB film formula, can significantly improve the mechanical index such as tensile strength, shock resistance of PVB film, and stability and the homogeneity of ageing-resistant performance, yellowing resistance energy and molecular weight, significantly reduce the inhomogeneous light distortion performance causing 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
The film of three kinds of formulas that above-mentioned formula is obtained carries out performance test, 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 automotive safety glass performance that common film makes, and is especially significantly improved in light distortion performance.
Above embodiment shows and has described 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; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; rather than 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.
