Environmental protection board for interior decoration and preparation method thereof

Abstract

The invention discloses an environmental protection board for interior decoration and a preparation method thereof. The environmental protection board for the interior decoration comprises a base plate and a polyethylene (PE) film arranged on the surface of the base plate, wherein a non-woven fabric layer is arranged between the base plate and the PE film, the base plate is composed of 50-80% of jute fiber, 20-50% of low melting point fiber and 0-30% of alpinia fiber based on weight percentage. According to the environmental protection board for the interior decoration, the base plate is compositely manufactured by the low melting point fiber and the jute fiber, the PE film further covers the base plate, no other composition is added, thus the fact that no other harmful chemical substance is contained in the environmental protection board for interior decoration is guaranteed, and the environmental protection board for interior decoration has no harm to a human body, meanwhile the jute fiber has good moist absorption performance and breathability, and is antimicrobial and mite proof. The environmental protection board is light and solid, capable of replacing decorative materials such as wall paper and paint, and can be used in places needing to be decorated such as a wall and a roof directly. The gram weight of a prepared product can reach to 100-500g / m2, and the thickness of the prepared product is 0.2-5mm.

Description

technical field

[0001] The invention relates to the technical field of decorative materials, in particular to an environmentally friendly board for interior decoration and a preparation method thereof. Background technique

[0002] At present, paints, wallpapers and composite floors are widely used in home decoration. These materials inevitably contain harmful substances such as formaldehyde and VOC, which will cause great harm to the human body. Therefore it is particularly important to develop environmentally friendly decorative materials.

[0003] In CN102300704A, a decorative panel formed of natural fibers and protective materials is disclosed, which is used for automotive decorative panels, including a base layer and a protective material, the base layer is generally formed of natural fibers, selected from: wood fiber, lignin Fiber or other cellulosic fibers such as wood, kenaf, hemp, jute, flax, ramie, roselle, rattan, soybean, okra, banana fiber, bamboo, coconut, coi...

Examples

Embodiment 1

[0029] The environment-friendly board for interior decoration is composed of a substrate 1, a non-woven fabric layer 3 on one side, and a PE film 2. Substrate 1 is composed of 50% flax by weight and 50% ES fiber by weight (skin-core structure, the skin is PE polyethylene, the melting point range is 125-135°C; the core is PP polypropylene, the melting point range is 145-165°C) .

[0030] The method for preparing the above-mentioned environmental protection board for interior decoration: weighing each component of the substrate according to the required ratio, pre-opening, mixing, fine opening, automatic cotton feeding, pre-forming, air-laid, upper acupuncture, Needle punching to obtain the substrate, put non-woven fabric on it, oven thermal bonding (170°C, 20min), cold rolling (0°C), cooling, and food-grade colored PE film (contact thermal bonding, 150°C) , Cutting to obtain the environmental protection board, it can be inspected and packaged; among them, the web forming speed...

Embodiment 2

[0033] The environment-friendly board for interior decoration is composed of a substrate 1, a non-woven fabric layer 3 on one side, and a PE film 2. Substrate 1 is composed of 80% jute by weight and 20% by weight PET bicomponent fiber (the skin is PET polyester fiber with a melting point of 110-120°C; the core is PET polyester fiber with a melting point of 260°C).

[0034] The method for preparing the above-mentioned environmental protection board for interior decoration: weighing each component of the substrate according to the required ratio, pre-opening, mixing, fine opening, automatic cotton feeding, pre-forming, air-laid, upper acupuncture, Needle punching to obtain the substrate, put the non-woven fabric on it, oven thermal bonding (230°C, 0.5min), cold rolling (30°C), cooling, and food-grade colored PE film (contact thermal bonding, 230°C ), cut to obtain environmental protection board, and then inspect and pack it; among them, the web forming speed is 1m / min; the needl...
