Description
Technical field
The present invention relates to a kind of anticracking tackiness agent and preparation method thereof.
Background technology
Light lath for building partition wall is a kind of novel environment friendly materials for wall.The advantage had is: solid, lightweight, Bao Ti, intensity are high, shock resistance, hanging force are strong, heat insulation, sound insulation, fire prevention, waterproof, easily cutting, easily slot.Main advantage: 1, efficient; Tradition is built a wall needs fragment of brick, cement, sand, water, stirring etc., and carrying is many, takes a lot of work consuming time, long in time limit.And use monarch's semi-annular jade pendant wallboard only to need installation one procedure, and dry operation, convenient and swift, time and labour saving.Save recruitment more than 60, the reduction of erection time is over half.2, reduce body of wall area occupied, increase the actual usable floor area 5% in house.3, structural cost is reduced; Light lath for building is only equivalent to common brick and builds a wall the weight of plastering, and the weight of brick is all saved, alleviates building structure load, improves Shock-proof for building shock resistance, reduces structural cost.4, save money; According to measuring and calculating, light lath house for building comprehensive cost every square metre is used to save 30-40 unit.But because light lath for building partition wall surface-area is comparatively large, specification mainly contains: " 2440 × 610 × 75,2440 × 610 × 90,2440 × 610 × 120 " three kinds of models (unit is mm).When batten is installed, leave 5mm gap between batten and batten, apply into flush joint with bonding mortar process.But, through one-year age, ftracture comparatively obvious.Cracking becomes the major obstacle factor of light lath for building partition wall application.
Flush joint is applied into, through observing: in 12 months, about 15% exists cracking in various degree, and the width average of cracking is at 0.1 millimeter, and maximum crack has 1 millimeter with bonding mortar process; The height of cracking generally at about 1 meter, maximum cracking even by the bottom of partition wall to top.Thus, prevent from ftractureing the technical task becoming and must capture.
Summary of the invention
The object of the present invention is to provide a kind of anticracking tackiness agent and preparation method thereof, solve gap between existing batten and batten and process rear problem easy to crack.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of anticracking tackiness agent, described anticracking tackiness agent is made up of the component of following weight percents:
Epoxy resin 20 ~ 30%
Epoxy curing agent 1 ~ 10%
Wheel turns high energy fountain solution 1 ~ 12%
Silicon carbide 55 ~ 85%;
Wherein, the weight percent sum of above-mentioned each component is 100%.
As a kind of selection, epoxy resin, the epoxy curing agent of 4%, the wheel of 5% that described anticracking tackiness agent is 21% by weight percent turn high energy fountain solution, 70% silicon carbide form.
As alternative selection, epoxy resin, the epoxy curing agent of 6%, the wheel of 8% that described anticracking tackiness agent is 26% by weight percent turn high energy fountain solution, 60% silicon carbide form.
As alternative selection, epoxy resin, the epoxy curing agent of 5%, the wheel of 6% that described anticracking tackiness agent is 24% by weight percent turn high energy fountain solution, 65% silicon carbide form.
Alternatively, described anticracking tackiness agent is 30% by weight percent epoxy resin, the epoxy curing agent of 3%, the wheel of 12% turn high energy fountain solution, 55% silicon carbide form.
A preparation method for anticracking tackiness agent, comprises the following steps:
(1) epoxy resin is added in container, and then epoxy curing agent is joined in described container, stir;
(2) in said vesse, then add wheel and turn high energy fountain solution, again stir;
(3) finally in said vesse, add silicon carbide, stir, obtain product.
The characteristic of epoxy resin and epoxy curing agent: (1) has diversified form, various resin, solidifying agent, modifier system almost can adapt to various application requiring, and its scope can from extremely low viscosity to high melting solid; (2) bonding strength is strong, due to the existence of polar hydroxyl groups intrinsic in epoxy resin and ehter bond, makes it have outstanding adhesion to various material; (3) shrinking percentage is low, the reaction of epoxy resin and solidifying agent used is undertaken by directly synthesizing, do not have water or other volatile by-products to release, epoxy resin, compared with resol, vibrin, only demonstrates very low shrinkability (being less than 2%) in its solidification process; (4) mechanical property, because epoxy resin contains more polar group, after solidification, molecular structure is comparatively tight, so the epoxy-resin systems after solidification has excellent mechanical property; (5) chemical stability, the epoxy-resin systems after solidification has excellent alkali resistance, acid resistance and solvent resistance.The epoxy-resin systems solidified that comprehensively makes of above-mentioned many performances has outstanding dimensional stability and weather resistance.
Wheel turns high energy fountain solution characteristic: can reduce surface tension.
Silicon carbide: have that color is pure white, hardness is high, toughness is slightly low, purity is high, self-sharpening is excellent, grindability is strong, thermal value is little, efficiency is high, a feature such as acid-alkali-corrosive-resisting, high temperature resistant, Heat stability is good.
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention turns high energy fountain solution, adamantine cooperation each other by epoxy resin, epoxy curing agent, wheel, and product of the present invention is had, and intensity is large, hardness is high; There is good effect of anti-cracking simultaneously, effectively can prevent the problem of Cracking between batten and batten.
