Abstract
The invention relates to an acryloid-type pressure-sensitive adhesive for a transparent polyester film door sticker of a high-temperature-resistant microwave oven, comprises the following components of 20-35 percent by weight of butyl acrylate, 5-15 percent by weight of methyl acrylate, 1-5 percent by weight of acrylic acid, 50-60 percent by weight of ethyl acetate and 2.2-3.5 percent by weight of melamine formaldehyde resin. The invention achieves the requirement on the microwave oven door sticker for resisting the temperature of 210 DEG C by changing the formula of the acryloid-type pressure-sensitive adhesive.
Description
Technical field
The present invention relates to a kind of compound method of pressure-sensitive adhesive, particularly disclose a kind of transparent polyester film door sticker of high-temperature-resistant microwave oven Acryloid-type pressure-sensitive adhesive.
Background technology
It is that to adopt thickness be that the transparent polyester film surface coated vinylformic acid solvent-borne type pressure sensitive adhesive of 0.1mm is compound with release polyester film after drying that the coventional type microwave oven pastes with door, final shape by die-cutting.The appearance requirement that door for microwave oven pastes is transparent, clear, must not there be bad phenomenon such as cut, scratch, bubble on the surface, physical index is 90 ° of stripping strength 〉=10N/25mm, (polyester film of surface coated solvent-borne type pressure-sensitive adhesive is attached on the microwave oven door-plate behind heat baking 30min under 180 ℃ the environment outward appearance of its subsides must not flavescence, warp for 180 ℃ of heatproofs, sharpness must not weaken, and distance 1 chi can be seen No. 4 words of the Song typeface clearly).The high-temperature-resistant microwave oven door pastes and then need reach 210 ℃ of heatproofs.
No matter be if that single all being not difficult of outward appearance or physical index accomplished in the technical requirements of microwave oven with the door subsides, there is a lot of tackiness agent can both reach requirement on the market, but comprehensively all will to reach requirement very big with regard to difficulty for all indexs, sharpness has been arranged, stripping strength does not reach again, and vice versa.The existing adhesive formulation of the applicant has satisfied above-mentioned all requirements, but can only heatproof 180 ℃, only is suitable for the coventional type microwave oven.Can warp through 210 ℃ of baking back door subsides, fuzzy, and stripping strength reduces.
Summary of the invention
The objective of the invention is to address the deficiencies of the prior art, disclose a kind of transparent polyester film door sticker of high-temperature-resistant microwave oven Acryloid-type pressure-sensitive adhesive, make microwave oven paste 210 ℃ of high temperature of ability, and satisfy clear, transparent requirement with door.
The present invention is achieved in that a kind of transparent polyester film door sticker of high-temperature-resistant microwave oven Acryloid-type pressure-sensitive adhesive, its prescription comprises: butyl acrylate, methyl acrylate, vinylformic acid and ethyl acetate, it is characterized in that: also comprise terpolycyantoamino-formaldehyde resin in the component, the weight percent proportioning of terpolycyantoamino-formaldehyde resin and other components is
Butyl acrylate 20～35%,
Methyl acrylate 5～15%,
Vinylformic acid 1～5%,
Ethyl acetate 50～60%,
Terpolycyantoamino-formaldehyde resin 2.2～3.5%.
The present invention solves high-temperature-resistant microwave oven to paste the difficult problem that can warp with door after 210 ℃ of bakings, by changing the prescription of Acryloid-type pressure-sensitive adhesive, adjusts the linking agent addition in the tackiness agent, thereby reaches 210 ℃ of high temperature of ability.
Beneficial effect of the present invention is as follows:
1) technique effect: after process the present invention adjusts the addition of linking agent in the vinylformic acid solvent-borne type pressure sensitive adhesive, the microwave oven of the producing high temperature of 210 ℃ of polyester film door sticker abilities, and satisfy coventional type microwave oven all appearance requirement, meet consumers' demand with polyester film door sticker.
2) social effect: because of the demand to barbecue type microwave oven is more and more in the market, the high-temperature-resistant microwave oven of producing through the present invention is attached to very advantageous in the domestic like product with the polyester door, therefore in the same industry, have very strong competitive power, estimate that annual turnover can increase more than 20%.And can satisfy the requirement of esbablished corporations such as PANASONIC, be sold abroad.
3) economical effectiveness: because its economic benefit of increase of sales volume can be significantly increased, can increase by 1,000,000 yuan of sales volumes every year approximately.
Embodiment
In order to make microwave oven, mainly be to need the polyester film behind the coating vinylformic acid solvent-borne type pressure sensitive adhesive can be pasted firmly difficult drop-off with the microwave oven door-plate with 210 ℃ of high temperature of polyester film door sticker ability.Draw by analysis, the base adhesion force that only increases tackiness agent also must be considered the heat resistance of tackiness agent not enough, and the temperature tolerance that the strengthen tackiness agent then linking agent in the tackiness agent plays crucial effects.The linking agent kind of Shi Yonging is more in the market, so at first need seek suitable crosslinking agent, secondly also will determine the addition of linking agent.
Should consider when selecting linking agent that temperature tolerance also will consider sharpness, the changing conditions of food because microwave oven needs to heat in the visual observation stove in use, so the sharpness that door pastes also is the important factor that can not be ignored, the selected linking agent of the present invention is a terpolycyantoamino-formaldehyde resin, can satisfy above-mentioned requirements.Because of the consumption of linking agent can have influence on heat resistance, if consumption is too much,, make tackiness agent become harder though increased the temperature tolerance of tackiness agent, surface viscosity reduces, and weakens with microwave oven door-plate bonding strength, very easily warps through high bake.So the temperature tolerance and the bonding strength that how much directly have influence on tackiness agent of linking agent addition, from this breach, through the final definite consumption of terpolycyantoamino-formaldehyde resin in vinylformic acid solvent-borne type pressure sensitive adhesive in a large amount of tests back be 2.2%～3.5% o'clock the most suitable, after sticking on the baking oven baking 30min that places 210 ℃ on the microwave oven door-plate through the polyester film behind the coating binder, neither warp, do not have variable color, bad phenomenon such as fuzzy again, reach the requirement that high-temperature-resistant microwave oven pastes with door fully.Paste after how tame client uses with door with the present invention's high-temperature-resistant microwave oven of producing of filling a prescription, all get the nod, meet the requirements fully.
Transparent polyester film door sticker of high-temperature-resistant microwave oven of the present invention comprises with the prescription of Acryloid-type pressure-sensitive adhesive: butyl acrylate, methyl acrylate, vinylformic acid, ethyl acetate and terpolycyantoamino-formaldehyde resin.
