Abstract
The invention discloses a removable adhesive for a mobile phone protective jacket, relating to a double-sided sticking material. The removable adhesive is the double-sided sticking material and is characterized in that the outer side surface sticking material of the double-sided sticking material is formed by an acrylic ester pressure-sensitive adhesive, and the inner side surface sticking material of the double-sided sticking material is formed by a nitrogenous acrylic ester hot melt adhesive; the inner side surface sticking material is coated on the inner side surface of a polyester film base material by extrusion and then is heated to form a hot melt adhesive tape, the outer side surface sticking material is coated on the outer side surface of the base material of the hot melt adhesive tape. The removable adhesive gives consideration to natural environments in different regions, the sticking force of the inner side material of the removable adhesive is strong and the inner side material of the removable adhesive is ensured to be firmly bonded in a protective jacket without separation, the sticking force of the outer side material of the removable adhesive is moderate, so as to be capable of ensuring a mobile phone not to fall off from the protective jacket due to gravity of the mobile phone after the protective jacket is used for a long time and enabling the mobile phone to be taken down from the outer side material in case the mobile phone is needed, and besides, decorative materials such as ink and the like on the back surface of the mobile phone cannot be torn down and the appearance of the mobile phone is prevented from damage.
Description
Technical field
The present invention relates to a kind of double faced adhesive material, particularly relate to one.
Background technology
In the past, for mobile phone is fixed in protective sleeve, conventional way is four oblique card articles that four jiaos of the mobile phones of fastening are respectively set in protective sleeve, or two horizontal card articles of lower edge on the mobile phone that fastens respectively.This card article easily damages, and is difficult for repairing.Once out of joint, gently mobile phone can not be fixed; Heavy cause whole protective sleeve to be scrapped.So someone expects using adhesive material, and mobile phone is sticked in protective sleeve.
But existing adhesive material has following shortcoming: 1, or cohesive force is inadequate, can not guarantee mobile phone in long-time use not can self gravity and from protective sleeve, fall down; Cohesive force is excessive, and when needs are but got to be got off when protective sleeve takes off mobile phone, even if taken off, adhesive material also can glue the finishing material such as the ink at the mobile phone back side get off, and has destroyed the outward appearance of mobile phone.2, the resistance to temperature variation of adhesive material indifferent, is adapted at that northern cryodrying environment uses, and has arrived southern high-temperature wet environment just not handy; Or contrary; Can not take into account the physical environment in district variously.Because adapting to various, inadaptable.
Summary of the invention
The present invention aims to provide a kind of moved glue for mobile phone protective cover, and it is a kind ofly can take into account the double faced adhesive material of the physical environment in district variously, and the material cohesive force of its inner side can be bonded in protective sleeve more greatly securely, and guaranteeing can be not separation with protective sleeve; The material cohesive force appropriateness in its outside; both can guarantee mobile phone in long-time use not can self gravity and from protective sleeve, fall down; can be to allow mobile phone to take off from his material outside at needs again, and the finishing material such as the ink at the mobile phone back side can not glued, destroy the outward appearance of mobile phone.
Technical scheme of the present invention is: for the moved glue of mobile phone protective cover, it is characterized in that: it is double faced adhesive material, and its outer side adhesive material is acrylate pressure-sensitive adhesive, and its medial surface adhesive material is nitrogenous acrylate hot-melt glue; This medial surface adhesive material is coated on the medial surface of polyester film base material and makes hot melt adhesive adhesive tape through heating in the mode of extruding; This outer side adhesive material is coated in the base material outer side of this hot melt adhesive adhesive tape.
The formula of described outer side adhesive material, has 5 parts of 100 parts of butyl acrylates, 8 parts of vinyl cyanide, 4 parts of N-n-butoxy Methacrylamides, 0.2 part of lauryl mercaptan and ethanol by weight; This nitrogenous acrylate hot-melt glue is sent into screw extrusion press, at 60 ℃, with the extruded velocity of 7 ms/min, is coated on polyester film base material, at 130 ℃, through heating in 5 minutes, makes described hot melt adhesive adhesive tape.
The formula of described outer side adhesive material has two kinds of components of first, second, first component has 2 parts of 190 parts of butyl acrylates, 6 parts of glycidyl methacrylate, 4 parts, vinylformic acid, 2.4 parts of lauryl mercaptans and benzoyl peroxides by weight, second component have be dissolved in 10% ethanolic soln 10 parts of zinc chloride, be dissolved in 37.5% vinyl acetic monomer solution 3 parts, trimethoxy propane, be dissolved in 3 parts of the triphenyl triisocyanates of 37.5% vinyl acetic monomer solution; First and second liang of components are coated in the base material another side of described hot melt adhesive adhesive tape by weight 1:1, at 100 ℃, through heating in 10 minutes, make.。
The present invention, for the moved glue of mobile phone protective cover, utilizes nitrogenous acrylate hot-melt glue to have very large cohesive force.Use the medial surface adhesive material of nitrogenous acrylate hot-melt glue as double faced adhesive material, can guarantee that double faced adhesive material is bonded in protective sleeve securely, can be not separation with protective sleeve.The cohesive force appropriateness of acrylate pressure-sensitive adhesive; repeatedly still can continue separation with bonded object used; use the outer side adhesive material of acrylate pressure-sensitive adhesive as double faced adhesive material; both can guarantee mobile phone in long-time use not can self gravity and from protective sleeve, fall down; can allow when needed again mobile phone to take off from its material outside, and the finishing material such as the ink at the mobile phone back side can not glued, destroy the outward appearance of mobile phone.Use polyester film base material as the separator between nitrogenous acrylate hot-melt glue and acrylate pressure-sensitive adhesive, to provide the basic condition of processing for producing this double faced adhesive material, so that produce nitrogenous acrylate hot-melt glue-line and the acrylate pressure-sensitive adhesive layer of uniformity.There is polyester film base material as skeleton, also this double faced adhesive material easy to use.The nitrogenous acrylate hot-melt glue that adopts above-mentioned composition and engineering to manufacture, as example, can reach 7-10kgf with the cohesive force of protective sleeve during take product size 80*30mm, and within the scope of envrionment temperature-40-+80 ℃, cohesive force is substantially constant.Can guarantee that double faced adhesive material is bonded in protective sleeve securely, can be not separation with protective sleeve.This nitrogenous acrylate hot-melt glue can also be water-fastness, repeatedly after washing, still can keep its cohesive force.The acrylate pressure-sensitive adhesive that adopts above-mentioned composition and engineering to manufacture, as example, is initially 1kgf with the cohesive force of mobile phone during take product size 80*30mm, after two days, can reach 3kgf, remains on 3kgf later always.Within the scope of envrionment temperature-40-+80 ℃, cohesive force is substantially constant.Both can guarantee mobile phone in long-time use not can self gravity and from protective sleeve, fall down, can allow when needed again mobile phone to take off from its material outside, and the finishing material such as the ink at the mobile phone back side can not glued, destroy the outward appearance of mobile phone.This acrylate pressure-sensitive adhesive can allow bonded object repeatedly bonding and Fen Li 300 times, can also be water-fastness, repeatedly after washing, still can keep its cohesive force.
