Abstract
The present invention relates to a foaming wallpaper production process, comprising the following steps: a substrate and a plastic thin layer are rolled and composited through rolling equipment; supercritical saturation is performed; pressure is released for separation; a plastic thin sheet is treated by foaming; the plastic thin sheet is examined and trimmed, and treated by elimination of static electricity; the plastic thin sheet is printed; the substrate surface is pasted with the plastic thin sheet; embossing is performed; and cutting and packaging are is performed. Advantages are that: the range of materials for foam wallpaper is expanded, the materials are not confined to PVC materials in the prior art, more choices are provided for the materials for the foam wallpaper, the disadvantages of difficult foaming quality control and environmental pollution and chemical foaming method can be overcome by a physical foaming method, the substrate and the foaming thin layer are closely attached, and the quality of the foam wallpaper can be improved.
Description
Technical field
The present invention relates to a kind of foam composite material and production technology thereof, particularly a kind of production technology of the wallpaper that foams.
Background technology
Advantage the liking more and more by people such as wallpaper is a kind of widely used indoor wall ornament materials, good decorating effect strong with rich color, skin texture texture.Existing wallpaper has plastic wallpaper, pure paper wallpaper, metal wallpaper, textiles wallpaper etc.Wherein the plastic wallpaper market share of occupying is maximum, can be divided into again common wallpaper and foaming wallpaper.
Existing foaming wallpaper technique; generally be only limitted to PVC foam wallpaper, kind is single, and existing PVC foam wallpaper adopts chemical blowing process; use chemical foaming agent in process of production; be unfavorable for environmental protection, and existing foaming PVC wallpaper adopts chemical blowing process, the chemical foaming agent used in producing; be unfavorable for environmental protection; and because the decomposition of chemical foaming agent is incomplete, have residue, unfavorable for product properties.
Along with epoch and technical development, physical blowing agent (carbon dioxide and the nitrogen) advantage of lower cost that physical blowing method uses, again can be fire-retardant, pollution-free, and noresidue after physical blowing agent foaming, little on the impact of foamed plastic performance, physical blowing method is more come in actual production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of production technology of the wallpaper that foams; the foaming wallpaper kind effectively overcoming prior art is single; chemical blowing process is adopted to be unfavorable for environmental protection; and because the decomposition of chemical foaming agent is incomplete; have residue, for product properties unfavourable defect.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of production technology of the wallpaper that foams, comprises the following steps:
Step 1: base material and plastic sheet are carried out calendering compound by rolling equipment, forms the semi-finished product wallpaper of rolling;
Step 2: the semi-finished product wallpaper obtained in step 1 is put into the adjustable high-pressure bottle of temperature and pressure, pass into supercritical gas again, temperature and pressure in high-pressure bottle is adjusted to setup parameter, makes saturated a period of time in the supercritical gas of semi-finished product wallpaper in high-pressure bottle;
Step 3: after the raw material after step 2 is saturated take out with constant release speed release, separation substrate and plastic sheet;
Step 4: plastic sheet step 3 obtained carries out foaming process by smooth warm-up mill;
Step 5: the plastic sheet after step 4 being foamed carries out elimination Electrostatic Treatment again after inspection, finishing;
Step 6: the plastic sheet after step 5 Electrostatic Treatment is stamped required decorative pattern and color by printing equipment;
Step 7: plastic sheet step 6 obtained is covered in the isolated substrate surface of step 3, obtains semi-finished product wallpaper;
Step 8: carry out embossing on the semi-finished product wallpaper that step 7 obtains;
Step 9: cutting, packaging.
As optimization, in step 1, above-mentioned base material is nonwoven fabric or the pure paper of good permeability.
As optimization, in step 1, the material of above-mentioned plastic sheet can be a kind of or several mixture in polyvinyl chloride, polypropylene, polyethylene terephthalate, polyethylene, polystyrene.
As optimization, in step 2, above-mentioned supercritical gas is CO
2supercritical gas or N
2one in supercritical gas.
As optimization, in step 2, the saturation time of above-mentioned semi-finished product wallpaper in supercritical gas is 8-24 hour.
As optimization, in step 3, above-mentioned saturated after raw-material release velocity interval be: be greater than 0MPa/min, be less than or equal to 20MPa/min.
The invention has the beneficial effects as follows: the scope expanding foaming wallpaper material therefor, it is made no longer to be confined to existing PVC material, for the material of the wallpaper that foams provides more choices, physical blowing is adopted to overcome environmental pollution and the unmanageable shortcoming of foaming quality of chemical blowing process, between base material and foaming thin layer, laminating closely, improves the quality of foaming wallpaper.
Detailed description of the invention
Be described principle of the present invention and feature below, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment: the production technology of the foaming wallpaper of the present embodiment comprises following step:
