Abstract

The invention relates to a TPU (Thermoplastic Poly Urethane) thin film smooth anti-blocking masterbatch which is characterized in that the masterbatch comprises the following components in percentage by weight: 70-90 percent of TPU, 2-10 percent of an anti-blocking agent, 2-10 percent of a smooth agent, 1-5 percent of a compatibilizer and 0.5-2 percent of an antioxidant; the total percentage by weight of the above components is 100 percent; a carrier of the masterbatch is an polyurethane elastomer; the anti-blocking agent is a Halloysite nanotube with a diameter of 30-50 nanometers; the smooth agent is one or more of organic stearate and silicon resin; the compatibilizer is one or more of silane coupling agent; the antioxidant is an antioxidant 1010 or an antioxidant 245 or an antioxidant 20N; the masterbatch is obtained by pelleting by adopting a traditional double screw blending process. The TPU thin film smooth anti-blocking masterbatch has the benefits that with the adoption of the TPU masterbatch provided by the invention, a TPU thin film has an excellent opening smoothness effect; the masterbatch is simple in production process and low in price, and the strength of the TPU thin film can be enhanced to a certain degree.

Description

The smooth antiblocking master batch of a kind of TPU film

Technical field

The present invention relates to the smooth antiblocking master batch of a kind of TPU film, belong to plastics functional agent technical field.

Background technology

TPU film, in production and use procedure, due to capillary existence, when pressurized or when being heated, to be easily bonded together and not easily separated.The adhesion of plastics film is many-sided reason, may be to form vacuum closed state because film closes between caudacoria, not easily separates; Also may be that after film forming, its surface has and a large amount of exposes molecular chain, after two panels film closes, create the mutual winding between macromolecular chain, make it open.In order to prevent the generation of this phenomenon, usually add a certain amount of opening slipping agent when producing plastics film.Common opening agent is inorganic talcum powder, diatomite etc., develops into organic amine hydroxybenzene, erucicamide and EBS derivative etc. afterwards, and at present synthetic silica to do slipping agent application in the film also comparatively extensive.

But there is side effect all to some extent in current used slipping agent, the problems such as main manifestations slipping agent is easily separated out, the dispersion of inorganic opening agent.Therefore, develop a kind of efficient, environmental protection, cheap TPU co-extruded films slipping agent is TPU membrane field problem demanding prompt solution.

Summary of the invention

The present invention, for solving above-mentioned the deficiencies in the prior art, its objective is that to provide a kind of opening smooth effective, and production technique is simple, and efficiently, environmental protection, the smooth antiblocking master batch of cheap novel TPU film.

For achieving the above object, the present invention solves the technical scheme that its technical problem adopts:

The smooth antiblocking master batch of a kind of TPU film, is characterized in that: this master batch comprises following component:

TPU:70-90%

Antiblocking agent: 2-10%

Slipping agent: 2-10%

Expanding material: 1-5%

Oxidation inhibitor: 0.5-2%

Above-mentioned each component concentration sum is 100%.

The carrier of this master batch is polyurethane elastomer.

Described antiblocking agent is the halloysite nanotubes of diameter 30-50nm.

Described slipping agent is one or more in organic stearate, silicone resin.

Described organic stearate is Zinic stearas or calcium stearate.

Described expanding material is one or more in silane coupling agent.

Described silane coupling agent is γ-methacryloxypropyl trimethoxy silane or vinyltriethoxysilane.

Described oxidation inhibitor is antioxidant 1010, oxidation inhibitor 245 or oxidation inhibitor 20N.

This master batch adopts traditional twin screw blending technology granulation to obtain.

The invention has the beneficial effects as follows: adopt the TPU master batch in the present invention, prepared TPU film has the excellent smooth effect of opening, and the production technique of master batch is simple, low price, and can the intensity of enhancement TPU film to a certain degree.
