Detailed description of the invention
The drawings are intended to provide a further understanding of the invention, and constitutes part of specification, with following tool
Body embodiment is used to explain the present invention together, but is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a kind of flow chart of embodiment of the preparation process of decorations plasterboard of the invention.
Specific embodiment
Detailed description of the preferred embodiments below.It should be understood that described herein specific
Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention provides a kind of preparation methods of decorations plasterboard, wherein the gypsum sheet material of preparation is utilized number
Control lathe is carved.
The present inventor has found by test of many times, is carved using numerically-controlled machine tool to gypsum sheet material, not only side
Just quickly, it is conducive to operation, is easily worked, and be less prone to crackle during engraving, product qualification rate is higher.
In the present invention, the numerically-controlled machine tool used can be commercially available engraving lathe.For example, the numerically-controlled machine tool can be
The numerically-controlled machine tool of the FPL-1530 trade mark of Suzhou Fei Pula numerical controlled machinery equipment Co., Ltd production.
In the present invention, mainly being obtained by being carved using numerically-controlled machine tool to gypsum sheet material has exquisite engraving figure
The decorations plasterboard of case, source and preparation method for gypsum sheet material do not specially require.Make in method of the invention
Gypsum sheet material can be any gypsum sheet material of commercially available qualification.
Engraving area is bigger or the higher carved product of hollow out rate in order to obtain, and under preferable case, prepares of the invention
The raw material of gypsum sheet material may include: the weight based on the raw material for preparing the gypsum sheet material, in the raw material αsemiwatergypsum and
The content of β semi-hydrated gypsum≤90 weight %, and the content of αsemiwatergypsum is 0-50 weight %.In more preferable situation, this hair is prepared
The αsemiwatergypsum of 5-50 weight %, the further preferably α of 5-30 weight half can be contained in the raw material of bright gypsum sheet material
Water gypsum.By adding a certain amount of αsemiwatergypsum in the raw material for preparing gypsum sheet material of the invention, carving can be significantly improved
Bigger or the higher carved product of hollow out rate the qualification rate of facet product.If the amount of the αsemiwatergypsum added in raw material is more than
50 weight %, the plasterboard ability higher cost of preparation, if the amount of the αsemiwatergypsum added in raw material is lower than 5 weight %, preparation
Gypsum sheet material intensity lower be unfavorable for carving that area is bigger or the higher carved product of hollow out rate.
According to embodiment of the present invention, the weight based on the raw material for preparing the gypsum sheet material, in the raw material
Including 0-50% αsemiwatergypsum, 20-40% β semi-hydrated gypsum, 5-30% silica flour, 5-30% alumine.
It further include one of glass fibre, water-reducing agent, retarder and defoaming agent or more in the raw material under preferable case
Kind.Glass fibre, water-reducing agent, retarder and defoaming agent type and dosage do not specially require, those skilled in the art can be with
It is selected according to actual needs.Under preferable case, the total weight based on αsemiwatergypsum and β semi-hydrated gypsum, glass fibre adds
Dosage can be 0.2-0.5%, and the additive amount of water-reducing agent can be 0.3-1%, and the additive amount of retarder can be 0-1%, disappear
The additive amount of infusion can be 0.1-1%.
In addition, further including water in the raw material.Dosage those skilled in the art of water can select according to actual needs
It selects.Under preferable case, based on the weight for the raw material for preparing the gypsum sheet material, the additive amount of water can be 50-100%.
Under preferable case, the preparation method further includes that mildew-retarding liquid is added during preparing the gypsum sheet material.It is anti-
It is only mouldy for the gypsum of wet environment, to avoid influencing its decorative effect.
In general, the method for preparing gypsum sheet material includes raw material mixing, molding, cutting and drying and other steps.According to the present invention
Method, can add mildew-retarding liquid in any one stage in mix stages and/or formative stage, under preferable case, form
Mildew-retarding liquid is added in stage can obtain the better decorated gypsum board of anti-mold effect.Meanwhile in existing molding procedure, without making
Under the premise of with any equipment, reaches mould proof and prevent plate from leading to the dual effect of plate cracking because forming the internal stress generated
Fruit.
According to the method for the present invention, the mildew-retarding liquid can be mildew-retarding liquid commonly used in the art.Such as the mildew-retarding liquid can
To be OBPA (the double phenoxazine arsenic of 10,10 '-oxos), and in use, based on the weight of the molding gypsum sheet material, institute
The dosage for stating mildew-retarding liquid can be 0.09-0.45%.Wherein, the dosage of the mildew-retarding liquid refers to the dosage of its effective component.
Method of the invention further includes that gypsum sheet material after molding is cut and dried.Cutting and dry method can
To use methods known in the art.
According to the method for the present invention, the preparation method further includes the gypsum sheet material surface spraying TiO after engraving2Light is urged
Change material.It was found by the inventors of the present invention that one layer of TiO of the surface even application of the qualified products after engraving2Catalysis material,
It is preferred that spraying TiO2The coating layer thickness of catalysis material is 0.1-0.5mm, can obtain the effect of purification air, can build one kind
Pure and fresh indoor environment achievees the effect that livable.Spray TiO2The method of catalysis material can use machine known in the art
Tool spraying method.
The present invention is further illustrated below with reference to embodiment, and the reagent used in the present invention, raw material are equal unless stated otherwise
For commercial goods.
Wherein, the anti-mold effect of the plasterboard is measured using GB/T 1741-2007 method;
The purification air effect of the decorated gypsum board is measured using QB/T 2761-2006 method.
