Abstract
The invention relates to a release coating material, which consists of the following components in percentage by weight: 0.5 to 0.7 percent of octadecylcarbamate, 0.075 to 0.125 percent of polyvinyl alcohol, 0.075 to 0.125 percent of amino ester and 99.1 to 99.3 percents of toluene. The release coating material has the advantages that: the release coating material has good compatibility with a solvent, is easily dispersed after being dissolved, does not produce a precipitate and is uniform in coating and good in release effect; and the solvent can be recycled.
Description
Technical field
The present invention relates to a kind of release coating material, relate in particular to the component of this release coating material.
Background technology
The function of release coating material is: behind release coating material and the solvent thorough mixing, utilize coating apparatus that it is evenly coated on the gluing reverse side base material of product, make product behind gluing, can this product uncoiling smoothly could be puted up use normally during use.
Release coating material is used to produce base materials such as fabricbase, broad film, paper and aluminium foil, must be coated on the base material with rational solvent cut to rational concentration, needs use heat solvent flashing, cured silicone after the coating.
Wait in use and release problem is an adhesive tape, kick the beam during uncoiling or overweight uncoiling power.Be to influence one of fabricbase adhesive tape quality important factor simultaneously.
What use in the prior art is that to gather the ethylene methacrylic radical siloxane release; This gathers the release weight percentages of components of ethylene methacrylic radical siloxane: gather ethylene methacrylic radical siloxane 7410#4-6%; Linking agent 91A0.5-1%, stopper 90B 0.5-1%, toluene 92-95%.
But thisly gather that the ethylene methacrylic radical siloxane is release to exist many defectives:
The first, be prone to produce the problem that silicon shifts, have a strong impact on the viscosity of glue; The silicon of product surface is because curing is bad, and poor adhesive force by gluing on the product, and is adsorbed onto Jiao Mianshang; So on the glue face one deck parting agent is arranged, causes glue not sticking.The off-type force that easy generation kicks the beam can influence normal uncoiling, during working aloft, in case the adhesive tape uncoiling will one slips to the end, seriously perplexs user's operation, to the user with unusual inconvenience;
The second, silicon solution is prone to deposition, and inhomogeneous, it is more inhomogeneous to cause being coated with silicon, can't uncoiling when often making the parent roll rewinding, cause a large amount of wastes; Because it is inhomogeneous to be coated with silicon, cause the product uncoiling occur can't uncoiling and be abandoned, cause the serious waste of product.
The 3rd, gather the ethylene methacrylic radical siloxane and solidify difficulty, cause quality unstable; Reach set time more than 48 hours; Occupy a large amount of storage capacity, solidification value is too high, and the high temperature that need reach 120 ℃ to 180 ℃ just can be cured; And 18 carbamates of existing invention, solidification value only need be at 50 ℃ to 70 ℃ with regard to the ability completely solidified.So original technology causes firing the cost superelevation of power power consumption;
The 4th, the siloxane solvent consumption is big.Original ethylene methacrylic radical siloxane processing compound ratio of gathering is 1: 5-1: 10.And 18 carbamate solution proportionings of existing invention are 1: 60-1: 120, reduced siloxane solvent greatly.And original process solvent can not utilize in gathering the ethylene methacrylic radical siloxane after reclaiming again; Cause siloxane solvent not recycle, because of in the content in the polymethyl benzene vinylsiloxane solution stopper 0.5-1% being arranged, the characteristic of this stopper is polymerizing curable and prevention solidified function; But meeting high temperature volatilizees easily; Owing to when reclaiming, need with 130 ℃ of steam volatilization toluene, but the volatilization postcooling liquefaction along with stopper is sneaked in the toluene in this polymethyl benzene vinylsiloxane solution; When treating to utilize after toluene reclaims; The content of the stopper of this polymethyl benzene vinylsiloxane solution kind exceeds 1%, serious prevention the curing of polymethyl benzene vinylsiloxane solution, cause shifting easily after this polymethyl benzene vinylsiloxane solution coat.A large amount of solvent discharges cause the seriousness environmental pollution in air, simultaneously, occupy high cost, sell to Company products and bring huge pressure.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of release coating material, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention is made up of 18 carbamates, Z 150PH, amino ester, toluene component; Its weight percent is: 18 carbamate 0.5-0.7%, Z 150PH 0.075-0.125%, amino ester 0.075-0.125%, toluene 99.1-99.3%.
Compared with prior art, the invention has the beneficial effects as follows: good with the consistency of solvent; The dissolving back is prone to disperse, and does not produce deposition; Coating evenly, and is release effective; Solvent is recyclable to be utilized again.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
Embodiment 1
Carbamate 0.6%, Z 150PH 0.1%, amino ester 0.1%, toluene 99.2%.
Amino ester, amino formate compounds can be used for synthesizing isocyanate, heterogeneous ring compound, nontoxic polyurethane, aminoresin etc. and alkene, aldehyde ketone generation addition reaction as the midbody of organic synthesis, can generate the product of various uses.In the present invention's (18 carbamate), be mainly dispersion, lubricated, release effect; Pva powder (PVA) is applied to various dry-powder putties, the additive in the dry-mix and ceramic tile tackiness agent, brushing gypsum sticker in the powder chemical building material etc.; In 18 carbamates, be mainly bonding amino ester, carbamate; Play amino ester, carbamate and at high temperature quicken to solidify, strengthen the material surface adhesion force and use.
Method of manufacture of the present invention is following:
Carbamate 0.6kg, Z 150PH 0.1kg, amino ester 0.1kg, toluene 99.2kg stirred 2 minutes, added in the agitator kettle, airtight pot mouth; Kettle temperature is heated to 70 ℃ and stirred 45 minutes; After stirring, put into the silicon-coated liquid bath, can begin coating and use.
The component that adopts among the present invention all is the commercially available prod.
