Description
Technical field
The present invention relates to a kind of finishing material, particularly a kind of repairing composition of antibacterial woodwork gap.
Background technology
Current China Development of China's Urbanization fast, is not only megalopolis area high buildings and large mansions, more brings hundreds of millions of building wastes.Building waste refers to that construction, unit in charge of construction or individual build all kinds of buildings, structures etc., lay or remove, produce in reparative processes dregs, spoir, rejected material, remaining mud and other wastes.Produce building waste according to measuring and calculating new building each ten thousand square metres and be about 500-600 ton, and the rubbish removing existent building generation is surprising especially, approximately every square metre produces the building waste of about a ton.Because Law-abiding cost is much larger than WeiZhao's Notes, the legal random disposal of building waste becomes current universal phenomenon.On the one hand, because building waste is arbitrarily disposed or simple landfill, take up an area and pollute again, and spoiled soil structure, cause ground settlement; On the other hand, the construction refuse regenerated enterprise the having a disposing capacity but for want of former material of building waste, is faced with the existence awkward situation of " not haveing enough to eat ".Have data to show, China's building castoff resource rate is less than 5%, and the annual resource rate of European Union member countries is more than 90%, and Korea S, Japanese architecture waste material rate reach more than 97%.Urban construction, transformation are all being carried out every day; building waste every day is all in uninterrupted generation; the building waste work for the treatment of of China is very urgent; along with China is for protecting farmland and the promulgation of every laws and regulations of environment protection and enforcement, how treatment and discharge building waste has become the important topic that enterprise in charge of construction and environmental protection department face.
Along with improving constantly of people's living standard and quality of the life, people more and more pay attention to the layout in room and style, and the inner wall surface in room play in whole decoration link basis effect, the especially promotion and application of coating and paint, make the color of metope and texture more and more colourful.But metope, when brushing these finishing material, must use interior wall composition to carry out smooth surface of wall
Process.In addition, composition also plays the effects such as important bonding transition between body of wall basic unit and film layer, and simultaneously also the texture decorative effect of topcoat, water-fast wearing quality play important effect.Therefore, interior wall composition is very important material in construction and decoration.According to the consideration in its effect and environmental protection etc. in interior decoration, generally there is nontoxic, the aspect requirement such as water tolerance, alkali resistance, slip-off preventing, anticracking for interior wall composition.Particularly because the application of water-borne coatings in interior decoration is more and more extensive, and bonding consistency good between water-borne coatings also becomes the performance that interior wall composition should possess.Most interior wall composition needs to add the requirement that Tackifier materials and various auxiliary agent could meet the aspects such as water tolerance, alkali resistance, slip-off preventing, anticracking in the market, but the volatile chemical often having formaldehyde etc. harmful in these Tackifier materials and auxiliary agent.Therefore the content reducing objectionable impurities in interior wall composition does not affect the important development direction that the salient featuress such as the water tolerance of composition are interior wall compositions simultaneously.
And in the middle of practical application, owing to being subject to the impact of seasonal variation and rainfall and air regime, especially in the area that humidity is rainy, the microorganisms such as the composition layer of interior wall and the easy breed bacteria of dope layer, mould, it is attractive in appearance but also can grievous injury HUMAN HEALTH that this not only affects metope.The interior wall composition with antibacterial not only can prevent the growth of metope mould, extends the use longevity of self
Life, but also effectively can assist and kill various germ in indoor environment, builds more healthy living environment, and therefore people are also more and more higher to the be fed up demand can with antibacterial of interior wall.Usually reach to make to be fed up by adding organic heterocyclic nitrogen-group fungicide and inorganic oxide class antiseptic-germicide there is the object of antibacterial, the shortcoming of both is also clearly: the biohazardous of organic sterilant self is high, inorganic oxide class antibacterial antiplaque agent weak effect, and both long-lasting all non-constants.
In sum, exist in this area long acting antibiotic and keep the water tolerance environment protection interior wall of good conventional application performance to be fed up the needs of composition.
Summary of the invention
For the deficiency that prior art exists, one of technical problem to be solved by this invention is to provide a kind of Environmental Safety, nontoxic, smell is pure and fresh, and a kind of environmental type with health-care effect can repair the antimicrobial compound in gap; Certain suppression, killing action is had to the multiple germs such as staphylococcus, intestinal bacteria, gram-positive bacteria and fungi; Simultaneously fragrant odour, pure and freshly soothes the spirit, pressure of releiving, also can expelling mosquito, can not produce detrimentally affect, be applicable to each age groups to human body.
The first object of the present invention is to obtain a kind of long acting antibiotic woodenware gap composition, and keeps good conventional application performance.
In another aspect of this invention, provide kind of a long acting antibiotic woodenware gap composition, described composition forms primarily of following components by weight percent:
