A kind of PVC profile for wear-resistant indoor floor and its production method

Abstract

The invention discloses a PVC profile used for wear-resistant indoor floors. The weight ratio of each component in the PVC profile is: 77-84 parts by weight of vinyl chloride resin powder, 1.85-2.75 parts by weight of metal soap stabilizer Parts by weight, 1-2 parts by weight of polyol auxiliary heat stabilizer, 0.15-0.25 parts by weight of microcrystalline paraffin, 8-10 parts by weight of impact modifier ABS terpolymer, 1-2 parts by weight of ethylene-propylene rubber, kaolin 4-6 parts by weight; the present invention selects non-toxic raw materials to ensure the needs of household wear-resistant floors, and improves its wear resistance under the premise that the impact modifier ABS ensures the impact resistance of the original PVC profile itself; through Kaolin and metal soap stabilizers improve the flame retardant performance of PVC profiles; microcrystalline paraffin itself has small particles, which can easily penetrate into the PVC material, improving the water penetration resistance of profiles; the material itself is non-toxic and pollution-free , a wear-resistant floor suitable for home decoration, with good practical effect.

Description

technical field [0001] The invention relates to the field of preparation of PVC profiles, in particular to a PVC profile used for wear-resistant bottom plates and a production method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, and it has a large polydispersity. The molecular weight increases with the decrease of the polymerization temperature. PVC resin is a polar non-crystalline high polymer. Strong acting force, is a hard and brittle material with low impact strength. [0003] After the impact modifier is added to the PVC profiles currently on the market, the elastomer particles of the impact modifier can reduce the total impact-induced stress, and use the deformation and shear band of the particles themselves to prevent the expansion and grow...

Problems solved by technology

[0003] After the impact modifier is added to the PVC profiles currently on the market, the elastomer particles of the impact modifier can reduce the total impact-induced stress, and use the deformation and shear band of the particles themselves to prevent the expansion and growth of cracks and absorb The impact energy introduced into the material body, so as to achieve the purpose of impact resistance; but for PVC profiles in different fields, it not only needs to have impact resistance, but PVC profiles for indoor wear-resistant floor applications need to have impact resistance. , but also need to have fireproof, wear-resistant, prevent water penetration, non-pollution and other properties, ordinary commercially available impact-resistant PVC profiles are far from meeting this demand
