Abstract

The invention discloses a method for preparing a joint sealant by utilizing construction wastes, i.e. building rubbish. The method comprises the following steps: taking the building rubbish as one part of a raw material and directly preparing the heat-insulating, mould-proof, moth-proof and anti-permeable joint sealant with low cost and environment friendliness by utilizing the existing sealant production line. The joint sealant has the joint sealing and bonding double functions, is adjustable in color and is convenient to construct.

Description

A kind of method utilizing building castoff to prepare spackling
Technical field
The present invention relates to a kind of material of construction, be specifically related to a kind of method utilizing building castoff and building waste to prepare ceramic tile spackling.
Background technology
Ceramic tile has become one of the main building and ornament materials on inner-outer wall and floor, in order to avoid producing hollowing owing to expanding with heat and contract with cold between ceramic tile and ceramic tile, needing reserved certain gap, and come filling gap with material of construction such as spacklings between ceramic tile.At present, main spackling is silicate cement, silica powder, methylcellulose gum, synthetic resins and mould inhibitor etc., as " thermal insulation elastic joint filling agent " (CN.200810046400.0), " preparation method of high quality ceramic tile crack filling agent " (CN.96115732.1), " colorful calking material for construction " (CN200510100265.X), " color tile grout " (CN00117192.5), " a kind of thermal insulator and manufacture method thereof " (CN200710011250.5), " a kind of method for filling gaps of ceramic tiles for walls and floors " (CN201010017639.2), " alkali-resistant high-class ceramic tile sealant " (CN201010103459.6), " a kind of preparation method of flashing compound for tile " (CN201010244403.2), " color tile grout and preparation technology thereof " (CN201010617931.8) and " without base-return color ceramic tile joint mixture " (CN201110033133.5) etc.But these technology employ a large amount of industrial chemicals and mineral wealth (i.e. base-material), and raw material does not adopt solid waste, and both not environmentally, production cost was higher again, do not meet the developing long-term strategy of country.
On industrial chemicals, have utilize polyurethane waste material, patent that useless polypropylene fiber prepares spackling, as " a kind of Polyolefin based polyurethane pointing and preparation method thereof " (CN200610029183.5), but its base-material still employs a large amount of mineral wealth.
In addition, along with the development of economy and Urbanization Construction, old building transforming and dismounting, new building are built, the speed of infrastructure construction is also constantly accelerated.According to statistics, China removes 400,000,000 square metres of Old building every year, produces building castoff and building waste about 500,000,000 tons; Annual new building 2,000,000,000 square metres, produces building waste and is greater than 100,000,000 tons; Annual finishing 2,000 ten thousand overlaps new house, produces building waste 4,000 ten thousand tons.At present, China's building waste annual emissions is more than 6.4 hundred million tons.So a large amount of building wastes is dealt carefully with if do not carried out and direct landfill, has both tied up soil, polluted water soil resource and air ambient, wastes again the Mineral resources of China's preciousness.
Therefore, developing a kind of take building waste as the spackling technology of preparing of base-material, and both environmental protection, raw materials cost is lower again, has good development prospect.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of spackling technology of preparing being base-material with building castoff and building waste is provided.
Object of the present invention is achieved through the following technical solutions:
The preparation method of spackling of the present invention, comprises the following steps:
(1) building waste powder 1-90 part, quartz sand 0-90 part, gelling material 5-90 part, polymer glue powder 0-10 part, thickening water-holding agent 0-10 part, anti-accumulation of salt in the surface soil agent 0-10 part, anti-crack water-proof agent 0-10 part, air entrapment agent 0-10 part according to the mass fraction, is taken;
(2) above-mentioned raw materials is mixed, obtain spackling through ball milling or after stirring.
Compared with prior art, the advantage that the present invention has and beneficial effect comprise: (1) base-material employs building waste, both environmental protection, and production cost is lower again; (2) there is mildew-resistant, mothproof, impermeable function; (3) there is joint filling and bond difunctional; (4) heat-insulation and heat-preservation function can be had; (5) shades of colour can be prepared; (6) can thin layer construction, save time material-saving; (7) easy to operate, after only spackling of the present invention and suitable quantity of water need being in harmonious proportion, embedding ceramic tile seam, compress, after solidification, the fifth wheel on ceramic tile face is wiped clean.
