Abstract
The present invention relates to environmental protection type antistatic and anti-cracking putty powder which is composed of 2 to 5% of polymer powder, 15 to 35% of conductive materials, 20 to 30% of white cement, 3 to 8% of gypsum powder, 5 to 15% of bentonitic clay, 15 to 35% of quartz powder, 5 to 15% of talcum powder, 0.3 to 0.5% of water keeping agents, 0 to 1.5% of anti-cracking agents, 0.1 to 0.5% of dispersing agents, 0.1 to 1.0% of defoaming agent and 0.3 to 0.8% of reinforcement fiber. Due to the fact that the conductive materials having an antistatic function, impervious fillers and the reinforcement fiber having an anti-cracking function are added; meanwhile, high quality additives are also matched, the basic performance of the produced putty is ensured; meanwhile, the present invention has the antistatic functional characteristics of electromagnetic interference shielding, adsorption dust prevention, etc., and also has the advantages of environmental protection, no pollution, innocuity, no stimulation, good quality, quick drying, water resistance, crack resistance, easy grinding, strong adhesion force, etc.
Description
Technical field the present invention relates to a kind of functional putty powder that is used for construction wall, and particularly being used in has on the particular requirement place static, with the special-purpose antistatic anti-cracking putty powder of the matching used body of wall bottoming of antistatic coating.
The harm in some cases of background technology static is known by people already, every year is hundreds of millions of because of the loss that static caused, for this reason, at some static there is particular requirement, in places such as electronics, communication, computer, precision instrument, weaving, powder processing and flammable explosive gas, antistatic be safety in production and the necessary condition that ensures quality product always.
In general, the film coated surface resistance value is 10
12Below can eliminate the static charge that is accumulated in film coated surface, the standard A STM F150-98 of American Society Testing and Materials with resistance value 2.5 * 10
4～1.0 * 10
6The sheet material of ohm is called conductive sheet metal, and is 1.0 * 10 with resistance value
6-9The sheet material of ohm is called electrostatically dissipative sheet material, and these sheet materials can prevent the accumulation of static charge.Therefore, people adopt the place of conductive flooring usually at needs, adopt the method for pasting anti-electrostatic sheet material to reduce the loss that static comes.But this method but is not clearly for those to the antistatic extra high place antistatic effect that requires, and sheet material is not easy to clean, also easy-maintaining not, and the life-time service antistatic effect also can reduce gradually.
In recent years, along with the progress of antistatic technology and the development of coating technology, people generally adopt antistatic coating application concrete or cement basal plane, to obtain antistatic effect, facts have proved that this method is compared the anti-electrostatic effect that is produced with traditional pasting board mode, not only effect is obvious, and it is lasting to hold time.
Say that in a sense building coating is a kind of work in-process, have only through the construction film forming to be only final finished attached to the coating on the basal plane.In this process, though putty is the supplementary material in the building coating coating process, form a connecting link but it plays in metope basic unit and between filming, the vital role of bonding transition is also being born important functions such as preventing metope cracking, the peeling of filming, specific functionality simultaneously.
Along with the appearance of country to building materials hazardous and noxious substances limit standard, the environmental issue of putty, also be subjected to human consumer's extensive concern, how to develop and a kind ofly require environmental protection, energy-conservation, pollution-free, high hiding rare, life-span long, the putty that easy construction can satisfy the specific function needs has again become the development trend of putty from now on, at present, being seen antistatic putty product mostly is oil product both at home and abroad, and the aqueous antistatic putty of environment-friendly type yet there are no relevant report.
Summary of the invention is in conjunction with the development of modern antistatic technology and coating technology, the invention discloses the antistatic anti-cracking putty powder of a kind of environment-friendly type, adopt its prepared putty not only to have shield electromagnetic interference, prevent to adsorb anti-static function characteristic such as dust, also have advantages such as environment friendly and pollution-free, nontoxic, non-stimulated, thick matter, fast dried, water-fast, freedom from cracking, easy polishing, strong adhesion.
The antistatic anti-cracking putty powder of this environment-friendly type of the present invention comprises following component: the talcum powder of the wilkinite of the white cement of the polymer powder of the 2-5% of counting by weight percentage, the electro-conductive material of 15-35%, 20-30%, the terra alba of 3-8%, 5-15%, the silica powder of 15-35%, 5-15%, the water-holding agent of 0.3-0.5%, the antichecking agent of 0-1.5%, the dispersion agent of 0.1-0.5%, the defoamer of 0.1-1.0% and the fortifying fibre of 0.3-0.8%, and all component per-cent sums are 100%.
Wherein, polymer powder is esters of acrylic acid, vinyl acetate class elasticity or non-resilient copolymer emulsion dry powder, as elasticity such as pure third, phenylpropyl alcohol and vinegar third, vinegar uncle or non-resilient emulsion dry powder base-material etc.; Also can adopt polyvinyl alcohol resin dry powder.
Electro-conductive material is 100-800 purpose composite conducting mica powder, conductive zinc oxide, conductive carbon black, graphite etc.
Filler is the 425# white cement, 250-500 order terra alba, the wilkinite of 300-800 order smectites sodium base, 120-400 order silica powder, 250-400 order talcum powder etc.
Auxiliary agent is antichecking agent, dispersion agent and defoamer, is produced by German Kening Co.,Ltd (Cognis).
Water-holding agent can be the methylcellulose gum series products of molecular weight about 15000-40000.
Fortifying fibre is that length is polyacrylonitrile fibre or the carbon fiber of 1.0-3.0mm.
Proportionally, above each component of weighing fully stirred 15-30 minute with mediating stirrer after the oven dry successively, mixed powdery components, was packaged as finished product with the weather-proof dressing bag.
Compared with prior art, invention is filled a prescription in the selected starting material, added the fortifying fibre of the electro-conductive material with antistatic property, impervious filler and anti-be full of cracks effect, also mated high quality additive simultaneously, these just make the putty of producing guarantee that fundamental property simultaneously, have water-fast preferably and anti-cracking, can guarantee that enough once criticizing scrape thickness, effectively antistatic effect.
Compare with traditional wall putty, use this putty of being produced of prescription to have shield electromagnetic interference, prevent to adsorb anti-static function characteristic such as dust, but also have advantages such as environment friendly and pollution-free, nontoxic, non-stimulated, thick matter, fast dried, water-fast, freedom from cracking, easy polishing, strong adhesion, supporting with it antistatic coating, because of putty layer thickness is generally 1.5mm-5.0mm, conductive section increases, and can more strengthen its conductivity; Supporting with it conduction emulsion paint can reduce the conducting powder consumption, reduces cost, and shows that it is good ornamental, and it is big because of the conducting powder consumption that adds to have improved original conduction emulsion paint, the defective that can't show beautiful color; In addition, conduct electricity putty relatively with now general oiliness, because it adopts the water-based base material fully, organic solvent-free and harmful organic substance, compliance with environmental protection requirements, and be the single component powder morphology, packed and transported is convenient.
