Description

A kind of impervious high accuracy air brushing material of analysing

Technical field

The present invention relates to the textile material field, be specifically related to a kind of flexible composite as painting advertisement cloth.

Background technology

Along with progress, the extensive stock of society are abundant greatly, the advertising development rapidly, this just certainly will propose higher requirement to advertising media, and hard materials such as prevailing neon light, plastic cement film and lucite can not satisfy the demand of advertising in advertising media in the past.Developed a kind of new high-tech product both at home and abroad in recent years in succession---flexible lamp house cloth (being flexible air brushing material), its appearance has broken through and can only utilize hard material to manufacture the forbidden zone of lamp box.Flexible air brushing material belongs to the fiber reinforcement type composite. and framework material is generally woven fabric or twin shaft to the WARP-KNITTING base cloth, and composite is polyvinyl chloride (PVC) film.Its advantage shows: picture color is dazzlingly beautiful, long service life, and convenient transportation uses safety; Directly adopt the numerial code spray drawing mapping, can not only form beautiful literal, more can present complicated beautiful pattern; Can make large-scale or super-huge advertising lamp box, and can the plane, any moulding of curved surface, it is more eye-catching to do lamp box at night than other materials.Has plurality of advantages just because of the advertisement of flexible air brushing material, though making it is 8O age Mo just to enter China, a few years in Shanghai, ground such as Beijing, Nanjing, Guangzhou, Zhuhai, Shenzhen, Shenyang developed rapidly. brought into play important function for setting up commercial ever bright city.Also because it has intensity height, light weight, weather-proof, water-tolerant, plurality of advantages such as moderate cost have been subjected to vast advertisement user's favor, and it is manufactured industry and has also obtained fast development.Nowadays, stroll the streets and lanes in the city,, to ground, lamp box advertisement of all kinds, Gorgeous Colouring is seen everywhere from the air.Also because of the fast development of IT industry, in the printing field, color and lines are meticulousr, breadth is more flexible, and picture is gorgeous more colorful, high accuracy color painting technology flexible Application, make advertising design to the development that becomes more meticulous more, domestic outdoor advertising has already entered sunny spring.

At present, though the air brushing material on the market is a feast for the eyes, its general adopt " cloth two films " are made, and namely strengthen the framework material layer by two-layer PVC film (facial mask and counterdie) folder one deck.Its processing mode is by knife scraping method, rolling process, three kinds of applying methods, door width of cloth maximum can reach 5 meters, this is enough to small-sized advertising, but for the outdoor large advertisement, also need handle by splicing, though present splicings such as hot melt are not having under the situation of air brushing, can accomplish that naked eyes can't differentiate, but the flushing phenomenon can appear in splicing place after air brushing of conventional air brushing material, and conventional air brushing material is too small to the absorbability of printing ink, separate out again after tending to cause printing ink to rest on surface even absorption, cause printing fastness and low precision, and can make that ink setting speed is slack-off, the set-off phenomenon takes place easily.Therefore, demand the impervious appearance that high accuracy is used the air brushing material of analysing urgently in high-precision large-scale advertisement field.

Splicing place of air brushing material is because after the modes such as hot melt that adopt handle, though surperficial PVC rete can merge mutually, do not having under the state of air brushing, can reach the boundary that naked eyes can't be differentiated, still seldom arrive effectively splicing after but its enhancing framework material layer is handled through splicing, the flushing phenomenon therefore after air brushing, very easily occurs, if after employing is soaked suitable glue to framework material, after carrying out high-temperature process again, this phenomenon will be able to effective improvement.The oil absorbency of air brushing material is the key factor of judging its quality quality in addition, it is to the adsorption capacity of printing ink, directly determine its degree of absorption to printing ink, the size that is related to the air brushing ink-supplying amount, and determine infiltration and the conjunctiva situation of printing ink on lamp house cloth, thereby influence printing ink be chromatic effect, China ink layer density and dot gain degree.The absorbability of conventional air brushing material is less relatively, printing ink can occur and rest on the phenomenon of separating out again after surface even the absorption when the high accuracy air brushing.And the absorbency of flexible air brushing material is determined jointly by PVC film, framework material and film and the framework material link material three of advertisement cloth, and therefore, prepare the impervious high accuracy of analysing must be from the collaborative research of three with the air brushing material.

At present, the pertinent literature report of the making of relevant flexible air brushing material has a lot, representational have: Xia Fenglin, Fan Xuerong from raw material select for use, warping requires, weaving until back arrangement etc. to having carried out the argumentation of system through the technological process of production of compiling the lamp house cloth product; The Liu schoolmate adopts the compound two step method of calendering-threes' layer heat to produce lamp box advertisement PVC spray painting cloth; Wang Lin, Lei Shuying etc. adopt PVC calendered film and terylene screen cloth heating applying are produced painting advertisement cloth, select for use titanium dioxide to make colouring agent; Patent CN2828108Y has reported the reflective lattice film spray painting cloth of the microprism that is manufactured by resin film, and patent CN201036935Y has reported transparent PVC is coated on chemical ﹠ blended fabric, Woven glass cloth or the cotton aspect, made the spray painting cloth with high brightness; Patent CN201072641 has reported polymeric membrane is placed on the base cloth layer of being made by cotton or high tenacity polyester fiber silk cloth and has made advertisement cloth, need not add plasticizer; Patent CN201070888 has reported by the base cloth layer of cotton or terylene and PVC macromolecule ink-absorbed coated layer and has made the two saturating cloth that can be used for advertisement; Patent CN2701897, CN2532100, CN1270886 etc. have reported with the laminated PU of dacron thread base cloth or PVC film and have made advertisement cloth; Patent CN 201102334Y has reported a kind of impermeable air brushing grid cloth, and it is a kind of layer structure, and it comprises the grid cloth base cloth layer of a high-strength textile material, the compound PVC coating of this base cloth layer one side, another side compound one firm PVC lining cloth layer.But above-mentioned document does not relate to impervious making of analysing the air brushing material.

In addition, the research about the lamp house cloth absorbency has: Liu schoolmate, Wang Xuedong etc. have analyzed influences the reason that the inking of PVC spray painting cloth is used in the lamp box advertisement; Haining Hua Yuanfa has introduced the spray painted cloth for lamp box of its production and has had ink absorption advantage preferably through compiling units such as new material Co., Ltd, and oneself has the pertinent literature report the good lamp house cloth of relevant ink absorption.But to adding the high absorbency that relatively large calcium carbonate is realized the PVC film under the acting in conjunction that utilizes the agent of calcium barium zinc metallic soap class Pickering, organotin liquid stabilisers, epoxidized soybean oil heat stabilizer assistant, and selected for use high-strength low contraction terylene silk weaving to make by after the processing of aqueous, environmental protective polyurethane glue impregnation, the framework material of handling through the hyperthermia drying pre-setting makes product printing ink flushing phenomenon can not occur in splicing place again, and this processing has further strengthened the absorbency of air brushing material, has avoided painting printing ink that surperficial osmotic phenomena takes place.Similarly handle and do not see in the literature with the absorbency that improves the air brushing material and the impervious property analysed and to address.

In sum, by optimizing the PVC film formulation, select for use high-strength low contraction terylene silk weaving to make framework material and adopt environment-friendly polyurethane glue impregnation after carry out pre-setting again and handle the prepared impervious air brushing material of analysing, such material is applied to large-scale high-precision painting advertisement cloth and has very important significance with the characteristics of intensity height and environmental protection.

Summary of the invention

Preferably, the described PVC paste resin-oatmeal degree of polymerization is 1300~1500.

Preferably, described calcium carbonate adopts the activated Calcium carbonate through the aluminate coupling agent activation.

The present invention carries out impregnation typing preliminary treatment to framework material to be made and eliminates the stress of weaving in the drawing process before the attaching process, thereby make cloth cover stiffening naturally and bonding intensity is high, and selected glue main component is aqueous polyurethane glue, it have do not fire, smell is little, free from environmental pollution, advantage such as operation is easy to process, performance is good.

The glue that high temperature pre-setting of the present invention is handled the major control framework material is in leather hard, and it can make gas fully be evaporated, otherwise gas can't discharge behind the meeting Yin Jiawen, and causes the air brushing material surface bubble to occur.

The present invention has selected for use the polyvinyl chloride resin powder (HPVC) of high polymerization degree to make the PVC film that makes have better physical performance (as: hot strength, compression, black brittleness, wearability, solvent resistance, heat-resistant aging), and all can keep relative preferable performance in wider temperature range.Corvic can be degraded under the effect of ambient light, oxygen, heat.Show by a large amount of facts that now the heat endurance of HPVC is better than PVC, this is that endgroup content reduces relatively because the molecular mass of HPVC increases, thereby the speed of taking off HCl slows down, and heat endurance improves.

It is auxiliary stabilizer that the present invention has selected epoxidized soybean oil ESO for use, it belongs to epoxy plasticiser, contain epoxide group in its molecular structure, in industrial polyvinyl chloride (PVC) process of resin, it can absorb the HCl that produces when the PVC resin decomposes, the continuous decomposition of retardance PVC, the free radical Cl that dissociates and in the time of catching the degraded of PVC resin again, stop the radical reaction of Cl, can make the active chlorine atom on the PVC chain stable, slow down degradation speed, play stabilization, prolong the service life of PVC goods.If with the metallic stabilizer synergy, its stablizing effect is more remarkable.Simultaneously, the compatibility of epoxidized soybean oil and PVC is fabulous, can be dispersed in fast in the PVC system, weakens the big intermolecular active force of PVC, increases intermolecular activity, the flowability of PVC is improved, thereby polyvinyl chloride resin is had plasticization.In addition, in PVC machine-shaping process, as long as add a spot of epoxidized soybean oil, will improve operating condition, improve process velocity, cut down the consumption of energy, improve the surface quality of PVC goods, and improve every physical property of goods to some extent, as heat-resistant aging, folding resistance etc., play positive role to reducing production costs and increasing economic efficiency.And epoxidized soybean oil and the class Pickering agent of calcium barium zinc metallic soap and organotin liquid stabilisers and time spent, epoxidized soybean oil has good synergistic effect.

The present invention though to be PVC traditional also is to use the earliest heat stabilizer for the lead salt heat stabilizer, have in PVC materials processing widely and uses aspect stabilizing agent selects for use.Its stability is good, and particularly long-time stability are good, and insulating properties is good, has the performance of Chinese white simultaneously, and covering power is big, good weatherability, and cheap.But its toxicity is big, compatibility and bad dispersibility, and along with global environmental consciousness is strengthened day by day, the regulation of relevant environmental protection is also strict day by day, therefore is not used in this invention.Generally acknowledge that in the world the heat stabilizer that can be used for the PVC non-toxic formulation mainly is organotin and complex Ca/Zn class.In all traditional hot stabilizer types, organotin is the most effective and the heat stabilizer of low toxicity (nontoxic), and organo-tin het stabilizer is many-sided to the stabilisation of PVC.It is generally acknowledged that they have had both the nearly all indispensable function of PVC heat stabilizer---catch, replace active chlorine atom, polyenoid addition and antioxidation, therefore shown the excellent comprehensive stablizing effect.Therefore, the present invention one of selects the organotin liquid stabilisers as the stabilizing agent of this product, but the organo-tin het stabilizer production cost is higher, market price costliness, and in the PVC process, can produce peculiar smell, therefore, behind the preferred a spot of liquid organic tin stabilizer of the present invention, also preferred calcium zinc metallic soap class Pickering agent, smell is few during their hybrid process like this.The agent of calcium zinc metallic soap class Pickering has characteristics such as cheap, nontoxic, efficient in addition, replaces unsettled chlorine atom generation ZnCl on the PVC chain but its mechanism of action of such stabilizing agent is zinc soap by ester group 2, and ZnCl 2Promote to take off HCl, along with blackening phenomena i.e. so-called " zinc burning " can take place rapidly in the prolongation that is subjected to thermal process.Therefore will add some auxiliary stabilizers in building-up process usually improves calcium zinc metallic soap class Pickering agent performance, and the epoxidized soybean oil that the present invention selects can be used as chelating agent and ZnCl 2Chelation takes place, and makes it innoxious.

Also added in PVC film process in addition by the activated Calcium carbonate after aluminate coupling agent activation as filler, the calcium carbonate that the present invention adds has been not only a kind of filler, also is a kind of important modifier.It can also improve hardness, elastic modelling quantity, dimensional stability and the heat endurance of goods when reducing cost.It carries out modification on the basis of ordinary calcium carbonate and obtains, thereby reaches filling in composite product and the dual purpose of modification.In recent years, show through further investigation, when with coupling agent calcium carbonate being carried out modification, the close inorganic end of coupling agent molecule and close organic end respectively can with surface and the organic resin generation chemical reaction of calcium carbonate, produce the entanglement effect with organic resin simultaneously, in the presence of crosslinking agent, also crosslinked phenomenon can appear.This effect has not only changed the surface polarity of calcium carbonate, has also increased the interfacial adhesion power of calcium carbonate and organic resin, so with coupling agent modified, not only can improve calcium carbonate-filled goods processing characteristics, also can improve the physical and mechanical properties of goods simultaneously.Calcium carbonate is carried out surface modification comparatively effectively titanate coupling agent and aluminate coupling agent.But meeting variable color owing to oxidation when using in some polymer with the calcium carbonate that titanate coupling agent was handled, so the present invention selects the calcium carbonate after aluminate coupling agent is handled for use.The adding of activated Calcium carbonate also is conducive to the air brushing material for the absorption of ink, therefore under stabilising system efficiently, the present invention can add the calcium carbonate of multiple dose more and not influence physical property of product itself, therefore, and conventional more superior of ink absorption of the present invention.

The present invention is by selecting the resin-oatmeal of high polymerization degree for use, measures such as the stabilising system of optimization product, interpolation activated Calcium carbonate, impregnation pre-setting framework material, elder generation's subsides counterdie post-facing film are to improve the impervious performance of analysing of air brushing material, prepared material is fit to high-precision large-scale numerial code spray drawing, this product also has the characteristics of environmental protection in addition, meets the developing direction of show and colour.
