Description

Technical Field

[0001] The utility model relates to a decorative base paper, in particular to a waterproof and breathable decorative base paper. Background Art

[0002] Decorative base paper is a kind of paper used for printing decorative layers, usually having specific thickness, whiteness and surface properties, and is widely used in the decoration of surfaces such as walls, floors, furniture, etc. At present, the common decorative base paper on the market is mainly a single-layer paper made of wood pulp, fillers and additives. It not only has general waterproof performance and is prone to cracking when encountering water, but also has general tear resistance and is easily torn. Therefore, the existing technology has problems of general waterproof performance and poor tear resistance. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waterproof and breathable decorative base paper. The utility model has the characteristics of effectively improving waterproof performance and enhancing tear resistance.

[0004] The technical solution of the utility model: the waterproof and breathable decorative base paper includes a back base paper layer, a flame-retardant waterproof and breathable film and a front base paper layer which are distributed in sequence. A printing decorative layer is arranged on the surface of the front base paper layer, and a polytetrafluoroethylene microporous membrane layer is arranged on the surface of the printing decorative layer; a plurality of rows of arc-shaped protrusion groups are respectively arranged on the upper and lower sides of the flame-retardant waterproof and breathable film, and the arc-shaped protrusion groups on the upper and lower sides are staggered; the front base paper layer includes an inner paper layer and an outer paper layer, and a grid-shaped glass fiber layer is arranged between the inner paper layer and the outer paper layer.

[0005] In the above-mentioned waterproof and breathable decorative base paper, a group of partition grooves arranged side by side are arranged on the back of the back base paper layer; a PE film is also arranged on the back of the back base paper layer.

[0006] In the above-mentioned waterproof and breathable decorative base paper, the thickness of the inner paper layer is half of the thickness of the outer paper layer.

[0007] Compared with the prior art, the utility model is composed of a back base paper layer, a flame-retardant waterproof and breathable film, a front base paper layer, a printing and decorative layer arranged on the front of the front base paper layer, and a polytetrafluoroethylene microporous film layer. From the inside out, there are a flame-retardant waterproof and breathable film and a polytetrafluoroethylene microporous film layer respectively, so that the decorative base paper not only has good waterproof and breathable performance as a whole, but also can improve the overall tear resistance of the decorative base paper to a certain extent. Moreover, in this application, by arranging a grid-shaped fiberglass layer in the front base paper, not only can the tear resistance of the base paper be effectively improved, but also the flatness of the surface of the front base paper layer can be ensured, and the printing effect of the printing and decorative layer can be guaranteed. At the same time, the utility model also improves the arrangement of staggered arc-shaped protrusion groups on both the upper and lower sides of the flame-retardant waterproof and breathable film, so as to effectively improve the connection performance between it and the back base paper layer and the front base paper layer, and improve the structural strength. To sum up, the utility model has the characteristics of being able to effectively improve the waterproof performance and enhance the tear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 is a schematic structural diagram of the utility model.

[0009] The reference signs in the drawings are: 1-back base paper layer, 2-flame-retardant waterproof and breathable film, 3-front base paper layer, 4-printing and decorative layer, 5-polytetrafluoroethylene microporous film layer, 6-arc-shaped protrusion group, 301-inner paper layer, 302-outer paper layer, 303-fiberglass layer, 7-partition groove, 8-PE film. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] The following further illustrates the utility model with reference to the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.

[0011] Embodiment. The waterproof and breathable decorative base paper is composed as Figure 1 shown, including a back base paper layer 1, a flame-retardant waterproof and breathable film 2, and a front base paper layer 3 arranged in sequence. A printing and decorative layer 4 is provided on the surface of the front base paper layer 3, and a polytetrafluoroethylene microporous film layer 5 is provided on the surface of the printing and decorative layer 4; a plurality of rows of arc-shaped protrusion groups 6 are respectively provided on both the upper and lower sides of the flame-retardant waterproof and breathable film 2, and the arc-shaped protrusion groups 6 on the upper and lower sides are staggered; the front base paper layer 3 includes an inner paper layer 301 and an outer paper layer 302, and a grid-shaped fiberglass layer 303 is provided between the inner paper layer 301 and the outer paper layer 302.

[0012] A group of side-by-side partition grooves 7 are provided on the back of the back base paper layer 1; a PE film 8 is also provided on the back of the back base paper layer 1.

[0013] The thickness of the inner paper layer 301 is half of the thickness of the outer paper layer 302.

[0014] The thickness of the inner paper layer is set to be half of the thickness of the outer paper layer, so as to ensure the flatness of the surface of the front base paper layer and the printing effect of the printing and decoration layer.

[0015] In this application, by covering the back of the back base paper layer with a PE film, the waterproof performance is further improved; by setting partition grooves (obtained by rolling) on the back of the back base paper layer and covering them with a PE film, not only the bonding performance between the decorative base paper and the installation item (such as floor, furniture) can be improved, but also the partition grooves can partition each area, reduce the connection between each area, and improve the waterproof performance.

[0016] The production process of this utility model: bond the inner paper layer, the glass fiber layer and the outer paper layer with glue and fix them by cold pressing; laminate the back of the back base paper layer with partition grooves on the back; then bond and press the back base paper layer, the flame-retardant waterproof and breathable film and the front base paper layer together with glue. Finally, print the printing and decoration layer on the front of the front base paper layer. After drying, stick the transparent polytetrafluoroethylene microporous film layer on the surface of the printing and decoration layer to obtain the waterproof and breathable decorative base paper.
