Abstract
The invention aims to provide a polyester resin film premix capable of lowering the consumption of a terminal blocking agent and volatile content of components in the technique and producing a high-hydrolysis-resistance polyester film. The polyester resin film premix is a mixture of a polyester resin with the inherent viscosity of 0.6-0.65 dl/g and a terminal blocking agent, wherein the terminal blocking agent accounts 0.6-1.2%. The polyester resin is an unsaturated polyester resin. The polyester resin is synthesized from trimethylolpropane and m-phthalic acid, and subjected to viscosity modification with a diluter. The terminal blocking agent is carbodiimide. The water content is controlled at 10-100 ppm.
Description
Technical field
The present invention relates to a kind of polyester resin film Preblend.
Background technology
Polyester has a large amount of carboxyls and hydroxyl conventionally in its surface, easily under the environment that contains moisture, is hydrolyzed, and often produces deterioration.Therefore, wait without under the environment being often exposed among wind and rain, the hydrolysis of the polyester that solar modules is used need to be inhibited.
In order to make polyester produce hydrolytic resistance, there is people to carry out catalytic hydrolysis reaction to it and reduce terminal hydroxyl, in order effectively to reduce terminal hydroxyl, tend to use some effective end closure agent as additive.
But the vibrin that is added with end closure agent has a lot of drawbacks when melt extruding, during melting mixing, end closure agent meeting produces the foreign matter such as gel, and the volatile component that part has neither part nor lot in reaction causes engineering to pollute, and operating environment is worsened.And the price of end closure agent is relatively high, a large amount of use has obstacle aborning.
Also incomplete in order to bring into play to greatest extent the effect of end closure agent, melt extrude the end closure agent reaction of adding in technique, thus after melt molding, unreacted encapsulant can continue to cause that capping effectively suppresses the increase of carboxyl.But just must excessive interpolation encapsulant in order to obtain this kind of effect.
And, in order to obtain the good polyester film of weather resistance, reduce terminal hydroxyl quantity, namely use the resin raw material that AV value is lower to obtain solid state polymerization particle.But when solid state polymerization particle is used, the very large shear heat of needs when improving limiting viscosity melting promotes the decomposition reaction of encapsulant.
But, during melting, in order to suppress resin decomposition, often adopt low temperature to extrude, but cannot fully carry out capping under low temperature, simultaneously, in the resin raw material of low temperature, the degree of crystallization of the nuclei of crystallization of molten component on film is not higher, and overtension during extension is difficult to launch completely.
Summary of the invention
The object of the present invention is to provide the polyester resin film Preblend of the polyester film that output anti-hydrolytic performance is good in the component volatilization amount in a kind of usage quantity and technique reducing end closure agent.
The present invention is achieved by the following technical solutions:
Described polyester resin film Preblend, comprises vibrin and the end closure agent mixing of limiting viscosity at 0.6～0.65dl/g, and end closure agent institute accounting is 0.6～1.2%.
Further, described vibrin is unsaturated polyester resin.
Further, described vibrin is that TriMethylolPropane(TMP) and m-phthalic acid are synthetic, and has carried out viscosity modification with thinner.
Further, described end closure agent is carbodiimide.
Further, moisture control is between 10～100ppm.
