[0045]

Embodiment 2

[0047] Calculated by weight, the PPF composite material includes: 45 parts of polyester fiber, 45 parts of polypropylene fiber and 10 parts of glass fiber. Its preparation method has been recorded in the manual, and the hot pressing parameters are: temperature 145°C, pressure 13Mpa, time 25min. Compared with Example 1, the PPF composite material added 10% glass fiber, and the test results are shown in Table 3, which shows that the glass fiber plays a certain role in improving the physical properties of the product.

Abstract

The invention provides a PPF (polypropylene fiber) composite material which comprises the following components in parts by weight: 10-80 parts of polyester fibers, 10-80 parts of polypropylene fibers and 0-50 parts of glass fibers. The invention also provides a preparation method and production equipment of the PPF composite material, and a floor containing the PPF composite material. Compared with the prior art, the prepared board is high in quality, the used environment-friendly materials do not contain halogen, stone powder and other fillers, and the board is small in density and light in weight. The hardness, the toughness and the stability are relatively high. The density of a PPF substrate provided by the invention is 0.9 g / cm < 3 >-1.3 g / cm < 3 >, the hardness is ShoreD 78-82, and the PPF substrate does not crack when the deflection is 15mm.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a PPF composite material, a preparation method and production equipment of the PPF composite material, and a floor containing the PPF composite material. Background technique [0002] In the construction industry, with the continuous improvement of people's health, environmental protection, aesthetics, comfort and other requirements, all kinds of decorative floors are developing in the direction of green and environmental protection. Most of the traditional plastic floors are made of polyvinyl chloride PVC, which is combined with a wear-resistant layer and a printing layer to form a plastic floor. This structure has been used until now. There are certain defects in the existing PVC substrate material formula, for example: (1) Wood-Plastic Composites (WPC) foamed substrates have poor stability; (2) Stone Plastic Composites (SPC) ) substrate density, high quality and w...
