Description
Technical field
The invention belongs to stool field, particularly relate to a kind of imitative stub stool and preparation method thereof.
Background technology
Existing stool Technology is the matter input of China, has spread several thousand, and the people this gate technique are also very many.
Existing stool is made as master with timber, also has the stool that the material such as stone material, bamboo, rattan plaited makes, but these materials mankind can resource-constrained, make in wastage of material resource, making processes and easily cause soil erosion and destroy ecotope.
Along with the raising of people's living standard, the requirement for practicality and artistry is more and more higher.But also there is not now the product of stool stub.The product that organic macromolecule unsaturated polyester resin, polyurethane resin material class are produced easily produces outside objectionable impurities, and its product itself does not reach the effect of stool stub yet; The plasticity-such as cement, gypsum of similar inorganic materials is strong and frangible, intensity, the performance such as wear-resisting are not high.
Summary of the invention
Technical assignment of the present invention is mainly for above-mentioned the deficiencies in the prior art, the present invention utilizes fabrication of new materials to go out " imitative stub stool ", can use as stool, not only shape-designing uniqueness, and material energy-saving environmental protection, fire prevention combustion, high-strength light, health care absolutely.
The invention provides a kind of imitative stub stool, with imitative stub stool raw material total weight, this imitative stub stool is made up of following weight percent raw material:
Magnesium oxide: 40% ~ 45%
Magnesium chloride: 20% ~ 22%
Water: 20% ~ 22%
Agricultural wastes: 5% ~ 10%
Flyash: 5% ~ 10%
Glass fibre: 1% ~ 3%
Additive: 0.5% ~ 2%.
As preferably, described additive comprise phosphoric acid, ferrous sulfate, Tai-Ace S 150, polyvinyl alcohol one or more.
As preferably, described agricultural wastes are wood chip.
The present invention also provides the preparation method of above-mentioned imitative stub stool, comprises the steps:
Step 1: magnesium oxide and magnesium chloride and water are uniformly mixed according to a certain percentage, then add flyash, agricultural wastes, glass fibre and additive, stir, obtain fabric;
Step 2: the fabric be stirred is carried out in product mold whitewash and filling, remove mould product shaping after certain hour;
Step 3: carry out spraying effect process at product surface, the stub effect making product reach design to want.
As preferably, in step 1, magnesium oxide and magnesium chloride and water are uniformly mixed with 1:0.5:0.5 according to weight.
As preferably, in step 2, certain hour is 4-8 hours.
As preferably, in step 1, the weight of flyash and agricultural wastes accounts for 10% ~ 20% of imitative stub stool raw material gross weight.
Advantageous Effects of the present invention is as follows:
(1) the present invention compares with traditional stool, is to utilize New Inorganic Materials to be made through scientific formula, and appearance design is unique, add its practicality and artistry, formed at normal temp solidifies, and does not need through calcining and other complicated technology, energy-conserving and environment-protective, manufacture craft is simple, and cost is low, product strength is high, lightweight, non-friable, nontoxic, tasteless, produce without obnoxious flavour, can be used for indoor and outdoor, beautifying the environment etc. for garden landscape has very high practicality and artistic value.
(2) the present invention utilizes magnesium oxide to combine with magnesium chloride, after fully reacting, produce the gelling material of high strength, solve product weight, flimsy problem, the particular design of product and product surface reach the stub effect of mixing the spurious with the genuine through spraying colored drawing, solve in traditional stool making processes this problem of wasting resource, environmental pollution, the present invention only needs 4-8 hours at shaping time, traditional stool manufacture craft also very complicated, operation is loaded down with trivial details, and the invention solves problems.
(3) the application is in auxiliary material, have selected agricultural wastes and trade waste, glass fibre and additive.Take flyash as the trade waste of representative, its wear resistance for product and intensity play important enhancement; And agricultural wastes can play cohesive action on the one hand, also greatly reduce the weight of product simultaneously; Glass fibre is also the material of important enhancing product strength; In order to better promote mixing and the condensation of raw material, the present invention selects the additive of one or more comprising phosphoric acid, ferrous sulfate, Tai-Ace S 150, polyvinyl alcohol.Therefore, the material energy-saving environmental protection of the application, fire prevention combustion, high-strength light, health care absolutely; Product have lightweight, intensity high, non-friable, nontoxic, tasteless, produce without obnoxious flavour, ambient cure, make simple, low cost and other advantages.
(4) the present invention also has energy-saving and emission-reduction, economizes on resources, lightweight, intensity good, nontoxic, without obnoxious flavour, nonpollution environment, making is simple, cost is low, production efficiency advantages of higher; And the product that the present invention produces meets green, environmental protection, healthy requirement.
