Description
Technical Field
The invention belongs to the technical field of glass explosion prevention, and particularly relates to a polyurethane coating, a high-transparency thermoplastic polyurethane outer explosion-proof coating and a manufacturing method thereof.
Background
Due to the high permeability and high strength of glass, a glass cover plate is used as a man-machine interaction interface of equipment in handheld electronic equipment, touch ATM (automatic teller machine), touch self-service ordering machines and the like in the market at present. The glass interface is broken by external force during use, and small and sharp glass fragments are splashed out by the broken glass interface, so that secondary damage is caused to a human body, and the damage is particularly serious on a vehicle. Therefore, the explosion-proof layer is manufactured on the glass interface, and the splash prevention after the glass is broken is of great significance. The existing explosion-proof and explosion-proof coating has defects in adhesion with glass and high-temperature water vapor resistance, so that the improvement of the existing explosion-proof and explosion-proof coating is needed.
Disclosure of Invention
Technical problem to be solved
In order to solve the problems in the prior art, the invention provides a polyurethane coating, a high-transparency thermoplastic polyurethane outer explosion-proof coating and a manufacturing method thereof.
(II) technical scheme
In order to achieve the purpose, the invention adopts the main technical scheme that:
a polyurethane coating comprising: 5-30 parts of aromatic polyester type polyurethane, 1-10 parts of aromatic polyether type polyurethane, 50-80 parts of dimethylformamide, 10-20 parts of butyl acetate and 0.1-5 parts of adhesion promoter;
the above raw materials are mixed and stirred to dissolve the aromatic polyester urethane and the aromatic polyether urethane, thereby obtaining the polyurethane coating.
The aromatic polyester polyurethane provides high-strength and high-adhesion of the coating on the glass substrate, and the aromatic polyether polyurethane provides high-strength boiling resistance and high-temperature steam resistance of the coating. The above component formula can provide high transparency of the coating. Wherein, the dimethyl formamide and the butyl acetate are good solvents of aromatic polyurethane, which is beneficial to obtaining high transparency.
The aromatic polyester urethane is a high molecular compound obtained by reacting dibasic acid with excessive polyol to prepare hydroxyl-containing polyester serving as a hydroxyl component, and then reacting the hydroxyl-containing polyester with phenyl-containing diisocyanate or polyisocyanate (such as toluene diisocyanate TDI). The aromatic polyether urethane is a high molecular compound prepared by reacting phenyl-containing diisocyanate or polyisocyanate (such as toluene diisocyanate TDI) with polyether polyol. Compared with two polyurethanes, the polyester polyurethane has better mechanical property and strong adhesiveness, but the high-temperature yellowing resistance is poorer, and the polyether polyurethane has better processing property and excellent hydrolysis resistance.
Preferably, the polyurethane coating further comprises 0.1-1 part by mass of a defoaming agent and 0.1-1 part by mass of a leveling agent.
The defoaming agent is beneficial to eliminating small bubbles in the coating, so that the prepared polyurethane coating (explosion-proof coating) has high transparency, transparency and touch control sensitivity. The leveling agent can ensure that the surface of the polyurethane coating has good smoothness after being coated on a substrate, and is favorable for obtaining good mirror transmission and touch control sensitivity. However, in order to achieve high transparency, the leveling agent and the defoaming agent should not be selected from self-colored raw materials, and the addition amount of the leveling agent and the defoaming agent should be strictly controlled.
Preferably, the adhesion promoter is a silane coupling agent, more preferably a silane coupling agent containing an aromatic carbon chain. Examples of the silane coupling agent include p-styryltrimethoxysilane, 3- (phenylamino) propyltrimethoxysilane, aminophenyltrimethoxysilane and the like. The silane coupling agent containing aromatic carbon chains has the following advantages: the aromatic carbon chain is similar to the aromatic polyurethane in structure, and according to the similar compatibility principle, the silane coupling agent can be more uniformly dispersed in the explosion-proof coating, and the aromatic carbon chain segment of the coupling agent has stronger bonding effect with the explosion-proof layer after the coating is cured.
Preferably, the polyurethane coating contains: 15-25 parts of aromatic polyester polyurethane, 5-10 parts of aromatic polyether polyurethane, 60-75 parts of dimethylformamide, 15-20 parts of butyl acetate, 2-3 parts of adhesion promoter, 0.4-0.6 part of defoaming agent and 0.4-0.6 part of flatting agent. By further optimizing the component consumption, the performances of high adhesion, high strength and high temperature water vapor resistance, high transparency and the like can be considered, and the comprehensive performance is optimal.
Preferably, the defoaming agent is one or a mixture of several of Tego-810, BYK-1711, CX-470 and basf-A10.
Preferably, the leveling agent is one or a mixture of more of AMS-2020, tego-270, RM-2020, tego-100 and HTK-3020.
Based on the conception, the invention also relates to a high-transparency thermoplastic polyurethane outer explosion-proof coating which comprises a polyurethane layer formed by coating and curing the polyurethane coating described in any one of the embodiments on a glass plate.
Preferably, the device also comprises a hardening layer; the hardening layer is arranged on the surface of the solidified polyurethane coating.
Preferably, the hardened layer is a UV type transparent plastic hardened layer or a thermosetting type transparent plastic hardened layer. The hardened layer can be obtained by coating and hardening any high-transparency hardened coating.
Preferably, the glass plate comprises a mobile phone panel, a tablet computer panel, a television glass panel, a front windshield cover plate, an advertisement electronic screen panel and the like.
Preferably, the thickness of the cured polyurethane coating is 10-20 μm.
Preferably, the thickness of the hardened layer is 5-10 μm, and the hardened layer coating is a conventional coating on the market.
