Abstract
The invention relates to adhesive tapes for building decorative gypsum boards and particularly relates to an environmentally-friendly adhesive tape for gypsum boards with non-wood pulp and non-paper pulp as raw materials. According to the environmentally-friendly adhesive tape for gypsum boards provided by the invention, a bonding layer is arranged on the surface of a substrate film of the environmentally-friendly adhesive tape for gypsum boards; the substrate film is made from a mixture of natural inorganic mineral powder, high-molecular polymer, natural starch and a plasticizer through a film preparation process; and the bonding layer is obtained by uniformly coating waterborne coating liquid containing oxidized starch and vinyl acetate on the surface of the substrate film and drying the waterborne coating liquid. The environmentally-friendly adhesive tape for gypsum boards provided by the invention has good initial bonding strength and final bonding strength with a water-wet gypsum board base material so as to prevent gypsum boards from being damaged in transport and processing processes. Compared with the existing adhesive tapes utilizing paper pulp or wood pulp as raw materials, the environmentally-friendly adhesive tape for gypsum boards provided by the invention avoids a large amount of pollution and resource waste problems generated in a papermaking process.
Description
Technical field
The present invention relates to the adhesive tape that the building decoration plasterboard is used, particularly a kind of plasterboard Environment protecting adhesive tape take non-wood pulp, non-paper pulp as raw material.
Background technology
Plasterboard is a kind of material of making take plaster of Paris as main raw material, it be a kind of lightweight, intensity is higher, thinner thickness, easy to process and sound insulation is adiabatic and the material of construction of the better performances such as fire prevention, be one of novel light sheet material of current emphatically development, be widely used in internal partition wall, body of wall cladding boards (replacement floated coat), top ceiling, acoustic panel, surface based laminate and the various decorative sheets etc. of the various buildingss such as dwelling house, office building, shop, hotel and industrial premises.Plasterboard is in transportation and use procedure; in the normal fibrous paper (claiming again adhesive tape) that adheres to protective in the surface of plasterboard; fibrous paper is removed again after installing plasterboard, according to statistics, only will consume millions of tons fibrous paper (claiming again adhesive tape) domestic every year.Plasterboard adhesive tape commonly used is with the very high kraft paper of intensity at present, at its surface coating modified amylan, executes in right amount water in gypsum board surface during use, and adhesive tape directly overlays on the surface of plasterboard, and it is sticking that amylan is met steeping in water for reconstitution, makes adhesive tape stick to the surface of plasterboard.The wet adhesive power of adhesive tape is strong, and permanent bond is good, bonding water and the weatherproof of curing situation, and tensile strength is good, and tension stress is large.Plasterboard installs, and throws off adhesive tape again, removes surface residues and polished finish.Kraft paper is to use acerose lumber fibre, through chemical pulping process, puts into hollander again and pulls an oar, and adds the processing such as sizing material, dyestuff again.The use of a large amount of kraft paper will consume large stretch of trees, and simultaneously making beating is processed and brought environmental pollution; In addition, because strong adhesive power, after adhesive tape was removed, the kraft paper at the surface of plasterboard meeting adhering residue needed follow-up polished and cleaned.
Summary of the invention
The objective of the invention is the problem that exists for above-mentioned adhesive tape take kraft paper as base material, provide a kind of replace the kraft paper base material take the mixture of high molecular polymer/mineral filler as base material, at the surface-coated tack coat of this base material, prepare the plasterboard Environment protecting adhesive tape again.
Plasterboard of the present invention is mainly used in the building decoration plasterboard with Environment protecting adhesive tape, and it has bilayer structure (as shown in Figure 1), with the surface of the substrate film of Environment protecting adhesive tape tack coat is being arranged as plasterboard; Described substrate film is the mixture by natural inorganic ore powder, high molecular polymer, native starch and softening agent, obtains (substrate film that obtains can further cut, and makes the substrate film of different size and size) by filming technology; Described tack coat is by the water-based coating fluid that contains Sumstar 190 and vinyl acetate, obtains after the surface through evenly being coated in substrate film and the drying.
The described substrate film that obtains by filming technology, that mixture with natural inorganic ore powder, high molecular polymer, native starch and softening agent joins in the homogenizer and mixes, through the screw extrusion press extruding pelletization, then carry out blown film, carry out press mold or apply masking through casting apparatus through rolling equipment through inflation film manufacturing machine according to conventional filming technology.
The content of natural inorganic ore powder is that the content of 50～75wt%, high molecular polymer is that the content of 20～25wt%, native starch is that the content of 4～20wt%, softening agent is 1～10wt% in the mixture of described natural inorganic ore powder, high molecular polymer, native starch and softening agent.
The particle diameter of described natural inorganic ore powder is 800～2000 orders; Be selected from one or more in Paris white, magnesium hydroxide powder, titanium dioxide and the magnesium ore powder etc.
Described high molecular polymer is polyethylene, polypropylene or their mixture.
Described native starch is selected from one or more in W-Gum, tapioca (flour), wheat starch, sorghum starch, the yam starch etc.
Described softening agent is selected from one or more in sorbyl alcohol, glycerol, ethylene glycol, dioctyl phthalate (DOP), diethyl phthalate and the dimethyl phthalate.
The composition of described water-based coating fluid and content are:
Sumstar 190 20～50wt%
Aqueous polyvinyl acetate emulsion 10～20wt%
Water surplus
The solid content of described aqueous polyvinyl acetate emulsion is 45wt%.
Described coating can be brushing, blade coating or flow coat etc.
The thickness of described substrate film is 50～200 microns, and this substrate film is compared with common fibrous paper has excellent tearing toughness and water resistance.
The thickness of described tack coat is 10～30 microns, has good adhesive property with plasterboard behind the wet water of this tack coat.
Plasterboard of the present invention can further carry out cotton ginning (stamp), embossment, the plasterboard Environment protecting adhesive tape that technique prepares all size such as punch, cuts with Environment protecting adhesive tape.Plasterboard of the present invention has good initial adhesion intensity and final cohesive strength with the plasterboard base material of Environment protecting adhesive tape and water-wet, has prevented the damage of plasterboard in transportation and the course of processing.Because plasterboard of the present invention has good tensile strength with Environment protecting adhesive tape, after plasterboard installed, this Environment protecting adhesive tape can be removed fully and not stay residue, need not to carry out polished and cleaned.Plasterboard of the present invention with Environment protecting adhesive tape be that the adhesive tape of raw material is compared with paper pulp or wood pulp at present, avoided a large amount of pollutions of in paper-making process, producing and to the waste problem of resource.Plasterboard of the present invention is cheap with Environment protecting adhesive tape, environmental protection, use properties are excellent.
