[0029] Such as figure 1 As shown, the preparation method of the film for formaldehyde-free environmental protection wooden floor that the embodiment of the present invention provides comprises:
[0030] S101: mixing and proportioning according to the mass fraction of each component;
[0031] S102: Using an extruder to plasticize the formula mixture, the plasticizing temperature is 180-210°C;
[0032] S103: Blow molding into foam, air-cooled at 20-25°C for shaping, traction, trimming, and winding into film.
[0033] figure 2 It is a formaldehyde-free environment-friendly wooden floor structure provided by the embodiment of the present invention, which is composed of film 1 and wood chips 2 .
Embodiment 1
[0035] Select 100 parts of HDPE, 1 part of EVA with a VAC content of 10%, 1 part of MA-PE with an acid value of 8 and 20 parts of fillers;
[0036] Use an extruder to plasticize the formula mixture, and the plasticizing temperature is 180°C;
[0037] Blow molding into foam, air-cooled at 20°C for shaping, traction, edge trimming, and winding into film.
Embodiment 2
[0039] Select 100 parts of HDPE, 7 parts of EVA with a VAC content of 20%, 10 parts of MA-PE with an acid value of 9 and 10 parts of fillers;
[0040] Use an extruder to plasticize the formula mixture, and the plasticizing temperature is 200°C;
[0041] Blow molding into foam, air-cooled at 22°C for shaping, traction, edge trimming, and winding into film.

Abstract
The invention belongs to the technical field of building and ornament materials, and discloses thin film used for a non-formaldehyde environmental friendly wood floor and a preparation method thereof.The thin film is prepared from, by mass, 100 parts of HDPE, 1-15 parts of EVA, 1-20 parts of MA-PE (maleic anhydride grafted polyethylene) and 0-20 parts of filler. The components are mixed in proportion according to mass fraction of the components, the formula mixture is plasticized by using an extruding machine, the plasticizing temperature is 180-210 DEG C, blow molding and foaming is carriedout, air cooling and shaping is carried out at the temperature of 20-25 DEG C, and pulling, edge cutting, rolling and film formation are carried out. The thin film is simple in process, and the provided thin film used for the non-formaldehyde environmental friendly wood floor can be used for manufacturing the wood floor which is water-proof, prevents insects, is formaldehyde-free, is free from extraneous odour, and is environmentally friendly.
Description
technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a film used for formaldehyde-free environment-friendly wood floors and a preparation method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Traditional solid wood flooring or solid wood composite flooring has poor weather resistance, and is prone to deformation and cracking when used for a long time in an environment with large changes in humidity and temperature. Existing composite wood floors are generally formed by laminating formaldehyde-containing density boards, wear-resistant layers, balance layers, and core fiber laminates. The formaldehyde in the formaldehyde glue used as the density board adhesive will slowly and continuously volatilize into the air at room temperature, resulting in a substantial increase in the indoor formaldehyde content, which can c...
