Description
Technical field
The present invention relates to material of construction material technical field, be specifically related to a kind of thermal-insulation energy-conservation environment protection plant fibre cementitious composite batten and preparation method thereof.
Background technology
Since entering the nineties, in the selection of living environment, people have been not content with general has it to occupy, but is pursuing material of construction and the new building materials of environmental harmony type with natural characteristic.Environmental harmony type building materials must meet heat preservation energy-saving, sound absorption sound insulation, water-proof fire-retardant, nonpoisonous and tasteless, lightweight, the characteristic such as high-strength, safe, plant fiber-cement composite strip plate is exactly a kind of novel environmental harmony type material of construction, selected vegetable fibre refers to annual fiber, mainly refers to that crop stalk is as corn stalk, straw, cotton stem, waste of flax etc.
At China's yearly plant abundance, be inexhaustible, nexhaustible raw material, their lifetime is shorter, does not have too large purposes after withered.These crop stalks through cut off hammer broken after obtained vegetable fibre feature be that length-to-diameter ratio is large, specific tenacity is high, specific surface area is large, density is low and biodegradable, have that cost is low, tensile strength advantages of higher in addition, replace timber to make cementitious composite batten strongthener, in use unharmful substance and obnoxious flavour generate.
But the alkaline attack effect of vegetable fibre extract to the anticoagulation of cement and cement-hydrate all limits the application of plant fiber-cement composite strip plate, show: the high alkalinity liquid phase in cement matrix hole has erosion action to vegetable fibre, thus affects the weather resistance of composite strip plate; Vegetable fibre has very high water-intake rate, the declining to a great extent of flexural tensile strength and Young's modulus after volume change can be caused to cause plant fiber-cement composite strip plate to make moist, and composite strip plate is distorted distortion, even ftractures; Vegetable fibre because there is depolymerization, making its polymerization degree decline and causing the corresponding reduction of its tensile strength under microbial process.For solving the problems of the prior art, need to carry out modification to existing plant fibre surface and reduce the alkalescence of gelling material.
Summary of the invention
Object of the present invention is just to provide a kind of thermal-insulation energy-conservation environment protection plant fibre cementitious composite batten and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of thermal-insulation energy-conservation environment protection plant fibre cementitious composite batten, it is characterized in that, be made up of the raw material of following weight part: vegetable fibre 27-37, silicate cement 28-35, flyash 45-50, discarded concrete 10-20, nano titanium oxide 1.3-2.7, Calcium Fluoride (Fluorspan) 0.2-0.4, calcium chloride 0.3-0.6, magnesium oxide 0.6-0.9, tubular fibre 4-7, benzene emulsion 12-15, oleum lini 4-7, polyoxylethylene abietate 9-11, water are appropriate.
The preparation method of described a kind of thermal-insulation energy-conservation environment protection plant fibre cementitious composite batten, is characterized in that comprising the following steps:
(1) within baking oven about 3-4 hour that vegetable fibre is put into 105 DEG C, dry, room temperature is dried, rap that to remove to pectin and be crushed to diameter be 3-6mm again with skin hammer, being placed on mass concentration is soak 24 hours in the benzene emulsion of 10%, press dry post-drying, air blast to the state of seething sprays into vaporific oleum lini, dries;
(2) discarded concrete is calcined 1-2 hour at 660-770 DEG C, cooling adds flyash agitation grinding 30-40 minute, add magnesium oxide and be warming up to 240-280 DEG C of stirring 5-10 minute, be cooled to 50-80 DEG C, add polyoxylethylene abietate to continue to stir 3-5 minute, be cooled to room temperature, dry porphyrize;
(3) calcium chloride be dissolved in water and stir 10-15 minute, add step (1), (2) reaction mass stirring and evenly mixing, add silicate cement and other remaining components again and stir 20-30 minute, it is shaping to add forming machine, obtains finished product successively after 20-30h through cutting, the demoulding, natural curing.
The present invention has following beneficial effect: it is easy that the present invention prepares simple operations, first benzene emulsion dip treating technique is taked to make the surfaces externally and internally of vegetable fibre be enclosed with one layer of polymeric film to plant fibre surface pre-treatment, spray vaporific oleum lini again, make whole fibre dense and obtain certain rigidity, and water tolerance improves; Secondly flyash is added and in addition modification replaces part of cement, the growing amount of calcium hydroxide after minimizing aquation, improve the corrosion resistance of vegetable fibre, choose the water cement ratio of 0.42 simultaneously, obtained plant fiber-cement composite strip plate has heat insulating, the advantage such as fire-retardant, improve the level of comprehensive utilization of vegetable fibre, reduce because waste resource deals with the grievous injury caused improperly.
