Definitions

• the present disclosure relates to a curable acrylic composition, an acrylic tape, an acrylic rubber roll and a method for preparing the acrylic rubber roll.
• dedusting adhesive tapes and rubber rolls can be used to clean various surface.
• Disposable dedusting adhesive tapes and rubber rolls are easy to use but are relatively high in cost.
• Reusable and water washable dedusting rubber rolls have become increasingly popular among price-sensitive and environmentally conscious consumers.
• Most water washable adhesive cleaning rolls in the market are composed of base materials such as natural rubber, synthetic rubber, silica gel or PVC, in which self-adhesive elastomer materials function as the adhesive layer and most of the surfaces are hydrophobic, resulting in unsatisfactory results when cleaning only with water, requiring cleansers or hot water to be when cleaning the rolls so as to reduce surface friction.
• a curable acrylic composition and an acrylic tape made from a curable acrylic composition and acrylic rubber roll composing said acrylic tape, wherein the acrylic rubber roll can recover its adhesion if washed with clean water without cleansers and is characterized by excellent cleaning ability and washability.
• the acrylic rubber roll can recover its adhesion if directly washed with clean water without cleansers, and is characterized by excellent cleaning ability and washability, easy cleaning of soft surfaces, and removal of lint, dandruff, dust, bits of thread, and so on that are attached to soft surfaces of household textile products, thus lowering the frequency for cleaning household textile products, especially clothing.
• a particular benefit is that in the acrylic rubber roll disclosed, the surface loses adhesion and becomes smooth when exposed to water, and the dirt attached to the surface can be easily removed with water without cleansers, and the acrylic composition can recover its viscosity after removing the moisture on the surface, and can be reused, reducing environmental pollution. After being reused many times, the acrylic rubber roll is still provided with good adhesion and rubber surface appearance, wherein the rubber surface is well bonded with the attached plastic roll, and the rubber surface is less likely to be detached if washed with water.
• a curable acrylic composition which comprises 50-77wt% 2-ethylhexyl acrylate, 2- 10wt% acrylic acid, 20-40wt% 2-hydroxyethyl acrylate, 0.1-0.5wt% curing agent and 0.1 -0.2wt% photoinitiator.
• the photoinitiator includes 2,2-dimethoxy -phenyl ketone.
• said curing agent is bifunctional acrylic ester.
• the bifunctional acrylic ester can include HDDA or TPGDA.
• the acrylic composition also includes one or more of: antiseptic, antibacterial agent, flavoring agent, plasticizer and fumed silica.
• One embodiment provides an acrylic tape formed by curing said acrylic composition.
• said curing includes UV light curing.
• One embodiment provides an acrylic rubber roll comprising a roll and said acrylic tape wrapped on the roll.
• One embodiment provides a method for producing acrylic rubber rolls, which includes: mixing and stirring 50-77wt% 2-ethylhexyl acrylate, 2- 10wt% acrylic acid, 20-40wt% 2-hydroxyethyl acrylate, and 0.1-0.5wt% curing agent at room temperature; adding 0.1-0.2wt% photoinitiator into the mixture, and continuing to stir until the photoinitiator is fully dissolved to form the acrylic composition; irradiating the acrylic composition with UV-light to make it crosslink and cure to obtain an acrylic tape; cutting the acrylic tape model corresponding to the size of plastic rubber roll shaft, and sticking said acrylic tape evenly without air bubbles to the rubber roll that can rotate freely so as to get said acrylic rubber roll.
• one or more antiseptic, antibacterial agent, flavoring agent, flavoring agent and fumed silica will be added into the acrylic composition.
• the stated curing agent includes bifunctional acrylic ester.
• the photoinitiator comprises
• a curable acrylic composition comprising 50-77wt% 2-ethylhexyl acrylate, 2- 10wt% acrylic acid, 20-40wt% 2-hydroxyethyl acrylate, 0.1-0.5wt% curing agent and 0.1 -0.2wt% photoinitiator.
• the acrylic composition also comprises other additive such as mildew preventive, antibacterial agent and flavoring agent, such as fumed silica and A-200.
• the curing agent has no special restrictions.
• the embodiment of the curing agent can include a bifunctional acrylic ester monomer such as HDDA and TPGDA.
• the photoinitiator has no special restrictions.
• the embodiment of the photoinitiator can be Irgacure 651.
• the curable acrylic composition in the embodiment of the disclosure is formed by mixing 2-ethylhexyl acrylate, acrylic acid, 2-hydroxyethyl acrylate, curing agent and photoinitiator according to ratios.
• the acrylic tape can be formed by curing the curable acrylic composition. UV-light can be used for curing.
• the acrylic rubber roll can be formed by wrapping the acrylic tape on the roll.
• the acrylic rubber roll can be used to clean surfaces of household textile products.
• acrylic composition can be applied on the roll, and then be crosslinked and cured to form the acrylic rubber roll used to clean surfaces of household textile products.
• a curable acrylic composition can be prepared with the same method in Embodiment 1. The difference lies in changing the ratios of 2-EHA, AA and HEA as shown in Table 1. Prepare the acrylic tape and the acrylic rubber roll with the curable acrylic composition prepared with same method in Embodiment 1.
• the acrylic tape and the acrylic rubber roll prepared in the embodiments and comparison cases are tested.
• the testing methods are as follows:
• Embodiment - 1 Easy to wash, no remaining lint
• Embodiment - 2 Easy to wash, no remaining lint
• Embodiment - 3 Easy to wash, no remaining lint
• Embodiment - 4 Easy to wash, no remaining lint
• the samples include the fresh rubber samples and soaked rubber samples.
• the method for preparing soaked samples is to soak the whole rubber sample in clean water and remove after 30 minutes of soaking. Place the rubber sample in a room at 22°C and humidity of 50% until the rubber sample is completely dry for testing.
• initial adhesion is one of the most direct indexes indicating roll performance. Since concepts such as washing and reusability are involved in use, the initial adhesion retention of soaked rubber samples is important too. With initial adhesion tests on fresh samples and soaked samples, the performance of washable rubber rolls in practical applications can be simulated.
• Embodiment- 1 , Embodiment-2 and Embodiment-3 have excellent initial adhesion retention, washing test results and initial adhesion test results for fresh samples and soaked samples.
• test sample measures 1 inch by 8 inches and is covered with standard dust.
• the sample is washed by hand with running water for about 15 seconds, then the water droplets are gently shaken off and the sample is allowed to stand for one minute in a 22°C and 50% relative humidity environment. These steps are then repeated (dusting, cleaning, and rinsing) 150 times before being allowed to dry for 5 minutes.
• testing is performed on Embodiment- 1 , Comparison Case- 1 and competing products (competing products are mostly produced by casting elastic materials such as synthetic rubber, polyurethane, and silica gel on a plastic roll shaft with a mould, and have names such as Sticky Lint Roller and Lint Cleaner, etc.) in accordance with Gl ASTM D6195.
• Embodiment- 1 After 150 cycles, the initial adhesion of Embodiment- 1 remained nearly the same while that the competing products fell by about 50%. In addition, the initial adhesion of the rubber tape of
• Embodiment- 1 is about 4 times greater than that of the competing product.
• the rubber tape of the embodiment of the present disclosure has long-lasting cleaning abilities for adhered dirt such as dust and lint. Compared with Embodiment- 1 , the washability data of the Comparison Case- 1 falls off slightly.
• the roll diameter of the rubber roller is 56mm and the roll is 98mm long.
• the natural dry time after washing is the adhesion recovery time of the rubber roll.
