Technical field

The invention belongs to the blend these fourth types polymer material systems of the copolymer of TPO, PVC, TPO and PVC, TPO and PVC A kind of standby technical field, and in particular to TPO super-hydrophobic coat and preparation method thereof.

Background technique

Thermoplastic elastomer (TPE) (TPE) is a kind of high resiliency with rubber, high-intensitive, high resilience, and has and can be molded The material of the feature of processing.TPE has environment-protecting and non-poisonous safety, has a wide range of application, there is excellent coloring, soft-touch is weather-proof Property, fatigue resistance and temperature tolerance, processing performance are superior, and without vulcanization, can be recycled reduces cost, both can be with quadric injection mould Molding can also be separately formed with the basis materials coating and bonding such as PP, PE, PC, PS, ABS.Therefore, it is often used as in automobile The effects of water on door and window cuts material, plays sealing, the water droplet on removal glass surface, water mist, dust and beauty.Olefines It is hard segment and EPDM as the blend of soft chain segment that TPE system, which is using PP, abbreviation TPO.(only due to its light specific gravity than other TPE For 0.88), heat resistance is up to 100 DEG C, resistance to weather and ozone resistance might as well, thus become the another product that have developed rapidly in TPE Kind.Since this type products surface easily stains object, it is badly in need of a kind of coating with self-cleaning effect.

Summary of the invention

Goal of the invention of the invention be to provide it is a kind of can facilitate it is molding, there is flame retarding function and will not influence molding matter The blend these fourth types polymer material of the copolymer of TPO, PVC, TPO and PVC of amount, TPO and PVC.

The blend of the copolymer of TPO, PVC, TPO and PVC with self-cleaning function of the invention, TPO and PVC this four The surface covering of quasi polymer material is achieved in that and calculates in parts by weight, comprising: takes 20~80 parts of fluorine carbon emulsion, titanium white 10~15 parts of powder, 10~15 parts of filler, 1~10 part of diluent, 10~20 parts of each analog assistant, mixing constitutes component A

5~15 parts of B component curing agent, 1~3 part of coupling agent, 1~3 part of promotor；1~3 part of nano-titanium dioxide, remaining For water

1: the group of the olefin hydrocarbons thermoplasticity elastic body TPO in the present invention becomes polypropylene PP 10-15%, ethylene-propylene-diene monomer Glue EPDM 20-30%, mineral oil 45-55%, carbon black 10-15%.The olefin hydrocarbons thermoplasticity elastic body (TPO) is with poly- third Alkene (PP) is hard segment and ethylene propylene diene rubber (EPDM) is the blend of soft chain segment.

2, the inorganic filler in the present invention: inorganic filler is added, can be further improved mechanical performance, heat resistance, ruler Very little stability and economy require that different amounts, different types of inorganic filler is added according to client's difference.Under normal circumstances, Inorganic filler can be one of calcium carbonate, titanium dioxide, talcum powder, silica, potassium carbonate, kaolin or at least two Mixture.A small amount of inorganic filler can also play the role of nucleating agent, and polyacrylic irradiation can be improved in the addition of nucleating agent Stability can be effectively reduced the degree of polymer degradation.

4, the component of the offer hydrophobic effect in the present invention includes fluorine carbon emulsion, nano-titanium dioxide.It weighs in proportion each Raw material premixes 5~10 minutes in high speed mixing smelting machine, places into paint mixer solubilizer and stirs 30-60 minutes.

Compared with prior art, the present invention having the following beneficial effects:

The coating that the formula is prepared through the invention is applied to the copolymer, TPO and PVC of TPO, PVC, TPO and PVC Blend these fourth types surface of polymer material after have self-cleaning function, can effectively improve the clean surface time of material, Prevent copolymer, the blend these fourth types surface of polymer material contamination dirt of TPO and PVC etc. of TPO, PVC, TPO and PVC.
