1. the blend these fourth types surface of polymer material of a kind of copolymer of TPO, PVC, TPO and PVC, TPO and PVC hardens Anti-scratch coating and preparation method thereof, which comprises the following steps:

Step 1,20~30 parts of extracting epoxy resin, it is 1~25 part of glass powder, 1~25 part of ceramic microsphere, 1~10 part of diluent, all kinds of 10~20 parts of auxiliary agent, 30~50 parts of polyolefin resin, 20~30 parts of filler, mixing constitutes component A；

Step 2,5~15 parts of B component curing agent, 1~3 part of coupling agent, 1~3 part of promotor；

Step 3, AB component mixed in equal amounts is uniformly coated on the copolymer of TPO, PVC, TPO and PVC, the blend of TPO and PVC The surface of these four types of polymer materials can achieve TPO, PVC, TPO and be blended with the copolymer of PVC, TPO with PVC's after solidification Object these fourth types surface of polymer material hardens anti-scratch effect.

2. the blend these fourth types of the copolymer of TPO, PVC, TPO and PVC according to claim 1, TPO and PVC are poly- Close object material surface hardening anti-scratch preparation method for coating, which is characterized in that the glass powder of the step 1 and ceramic microsphere Summing it up dosage is 15~30 parts, i.e. the addition of glass powder and ceramic microsphere be and/or relationship, the hybrid mode is mechanical mixed It closes.

3. the blend these fourth types of the copolymer of TPO, PVC, TPO and PVC according to claim 1, TPO and PVC are poly- Close object material surface hardening anti-scratch preparation method for coating, which is characterized in that the coupling agent of the step 2 is the idol of silanes Join agent.

4. the blend these fourth types of the copolymer of TPO, PVC, TPO and PVC according to claim 1, TPO and PVC are poly- Close object material surface hardening anti-scratch preparation method for coating, which is characterized in that alkali was wanted on surface to the step 3 before the coating Property solution cleaning deoil, dry.

5. the blend of the copolymer of TPO, PVC, TPO and PVC according to claims 1 or 2, TPO and PVC is these four types of Surface of polymer material hardening anti-scratch preparation method for coating, which is characterized in that the ceramic microsphere diameter of the step 1 is 10 ~15 μm.

6. the blend of the copolymer of TPO, PVC, TPO and PVC according to claims 1 or 3, TPO and PVC is these four types of Surface of polymer material hardening anti-scratch preparation method for coating, which is characterized in that the coupling agent of the step 2 will be added dilute It releases in agent in the hope of mixed uniformity.

7. the blend these fourth types of the copolymer of TPO, PVC, TPO and PVC according to claim 4, TPO and PVC are poly- Close object material surface hardening anti-scratch preparation method for coating, which is characterized in that the alkaline solution is the hydroxide of 1-35% Sodium solution.

Technical field

The invention belongs to the blend these fourth types polymer material materials of the copolymer of TPO, PVC, TPO and PVC, TPO and PVC Expect the technical field of preparation, and in particular to the blend of a kind of copolymer of TPO, PVC, TPO and PVC, TPO and PVC is these four types of Surface of polymer material hardening anti-scratch coating 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 the surface TPO is easy to be scraped off during use.

Summary of the invention

The purpose of the present invention is to provide copolymer, the TPO of a kind of TPO, PVC, TPO and PVC with scratch-resistant function With the blend these fourth types polymer material of PVC, with increase abrasion resistant component coating be coated in material surface.

1: the extracting epoxy resin epoxide number in the present invention is 0.1-0.25, and glass powder partial size is 1.5-2.5um, ceramic microsphere Partial size is 0.5-2.5um.

2: the curing agent in the present invention includes aliphatic diamine and polyamines, aromatic polyamine, other nitrogenous compounds and changes Property fatty amine further includes organic acid, acid anhydrides and boron trifluoride and its complex compound.
