Environment-friendly flame-retardant ship stone-plastic floor and method and device thereof

Abstract

The invention discloses an environment-friendly flame-retardant ship stone-plastic floor and method and device thereof. The environment-friendly flame-retardant ship stone-plastic floor comprises a hard PP / PE base material layer, a back coating balance layer is arranged at the lower end of the hard PP / PE base material layer, a PP / PE printing layer is arranged at the upper end of the hard PP / PE base material layer, and a UV coating is arranged at the upper end of the PP / PE printing layer. In the environment-friendly flame-retardant ship stone-plastic floor, PE resin is adopted to modify PP resin through a compatilizer to form a blending material, calcium carbonate filler with the optimal cost performance is adopted to develop a Non-PVC stone-plastic floor base layer, then a PP / PE printing layer added with a flame retardant is hot-pressed on a base material, the surface of a hot-pressed plate is coated with a protective layer of 0.10-0.30 [mu] m in a curtain coating mode, and finally slitting, slotting and packaging are performed. As the main component elements of the product are C and H, the smoke density and toxicity of gas after combustion are far lower than those of a traditional PVC stone plastic floor.

Description

technical field [0001] The invention relates to the technical field of stone-plastic flooring, in particular to an environment-friendly flame-retardant ship stone-plastic flooring and a method and device thereof. Background technique [0002] At present, flooring materials such as traditional PVC stone-plastic flooring are applying for MED ship certification. Its own composition contains chlorine, which has a self-extinguishing effect and can pass 100% of MSC307 (88) Part 5: Surface flammability test (surface materials and decks) base dressing). However, the PVC stone-plastic floor volatilizes irritating HCl gas and black smoke during the combustion process, and it is very difficult to pass the MSC307 (88) part 2: smoke and toxicity test. Even if a large amount of flame-retardant inorganic fillers such as Al(OH)3 or Mg(OH)3 are added to the formula, the pass rate is less than 0.1% according to statistical data, and the test results are quite random. Even if the small trial...

Problems solved by technology

Even if the small trial production passes this test, it is often sampled and tested in mass production. According to the test data from the British authoritative fire protection laboratory, the pass rate is only 0.05%, which is lower than the pass rate of the trial production sampling test. Instability, even if a certain sampling test passes during mass production, there will be situations where all subsequent sampling tests fail
