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 Standby technical field, and in particular to a kind of TPO, PVC, TPO polymerize with the copolymer of PVC, TPO with the blend these fourth types of PVC Object material surface uses hardening anti-scratch and with expansion type flame-retarding functional paint 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.But although simple TPO has many excellent performances, and with the raising that people require material multifunctionality, TPO exists Many aspects do not reach the requirement of people still, this is badly in need of us and develops a kind of TPO material with fire protecting performance.

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 flame retarding function of the invention, TPO and PVC is these four types of Polymer material is achieved in that and calculates in parts by weight, comprising: 20~30 parts of extracting epoxy resin, 10~15 parts of glass powder, and pottery 10~15 parts of porcelain microballoon, ammonium polyphosphate 5~10, melamine 5~10, pentaerythrite, 5~10,1~10 part of diluent, respectively 10~20 parts of analog assistant, 30~50 parts of polyolefin resin, 20~30 parts of filler,

5~15 parts of B component curing agent, 1~3 part of coupling agent, 1~3 part of promotor

1: the group of the olefin hydrocarbons thermoplasticity elastic body TPO in the present invention becomes polypropylene PP10-15%, ethylene propylene diene rubber EPDM20-30%, mineral oil 45-55%, carbon black 10-15%.The olefin hydrocarbons thermoplasticity elastic body (TPO) is with polypropylene (PP) be 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 fire retardant in the present invention includes ammonium polyphosphate, melamine, pentaerythrite.Each raw material is weighed in proportion, It is premixed 5~10 minutes in high speed mixing smelting machine, places into paint mixer solubilizer and stir 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 be applied to the copolymer of TPO, PVC, TPO and PVC, TPO and After the blend these fourth types surface of polymer material of PVC have flame retarding function, can effectively improve oxygen index (OI), prevent TPO, PVC, Copolymer, blend these fourth types polymer material burning of TPO and PVC of TPO and PVC etc..
