Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glasses manufacturing, and particularly relates to a manufacturing method of an antibacterial negative ion glasses frame. BACKGROUND

[0002] In the digital era, the problems of eye dryness, stinging, eye fatigue and eye lesions caused by long time close-to-eye use of electronic products and radiation are getting more and more serious, and people's awareness of eye health is gradually enhanced. The conventional glasses product has few negative ions without adding negative ion materials, and has no relieving effect on eye dryness, stinging and eye fatigue.

[0003] At present, there is a negative ion glasses product on the market, which is made by reserving a plurality of groove positions when the frame body is injection molded, and then injecting glue to install negative ion tourmaline particles. The frame manufactured by this manufacturing process may have the phenomenon of negative ion particle falling off in daily use, or the possibility of frame body fracture caused by structure change is increased.

[0004] In daily wearing, the nose pad and the glasses leg of glasses are the parts directly contacting the skin. In the case of incomplete cleaning, the human body sweat and the frame body may cause corrosion, chemical substances or bacteria to cause skin allergy. SUMMARY

[0005] The purpose of the application is to provide a manufacturing method of an antibacterial negative ion glasses frame, which can not only release negative ions to relieve eye dryness, stinging, eye fatigue and eye lesions caused by long time close-to-eye use of electronic products and radiation, but also effectively reduce the skin allergy caused by the bacteria breeding between the human skin and the frame.

[0006] To achieve the above purpose, the application adopts the following technical scheme:

[0007] A manufacturing method of an antibacterial negative ion glasses frame, comprising the following steps:

[0008] 1) Preparing a negative ion glasses frame body

[0009] TR plastic titanium and nanometer six-ring stone are configured into a frame body material according to a weight ratio of 0.83-0.85:0.15-0.17, and then the frame body material is stirred uniformly and granulated. The granulated frame body material is poured into a drying machine and baked at 95 DEG C for 4 h. Finally, the baked frame body material is poured into an injection molding machine barrel of a glasses frame mold, and injection molding is performed to obtain a negative ion glasses frame body.

[0010] 2) Preparing a mixed paint

[0011] The bright surface gold oil and the antibacterial silver ion are mixed uniformly according to a weight ratio of 0.91-0.92:0.08-0.09, and bubbles are eliminated after standing to obtain a mixed paint.

[0012] 3) Spraying paint on the negative ion eyeglass frame body

[0013] The mixed paint is filled into the spray gun, then the mixed paint is sprayed on the surface of the eyeglass frame body, and finally the finished frame body is baked and dried.

[0014] Preferably, in step 1), the weight ratio of TR plastic titanium to nanometer hexagonal stone is 0.84:0.16.

[0015] Preferably, in step 2), the weight ratio of bright surface gold oil to antibacterial silver ion is 0.92:0.08.

[0016] Preferably, in step 3), the spraying thickness of the mixed paint is 130 μm.

[0017] In step 1), the single screw extruder with a diameter of 65 mm is selected for the granulator, the kneading time is 500-510 min, and the extrusion rod temperature is 195℃, 200℃, 195℃, 195℃ in turn.

[0018] In step 1), the temperature parameters of the injection molding machine are as follows: the feeding section is 235℃, the middle section is 240℃, the discharge section is 245℃, the nozzle is 255℃, the mold temperature is 90℃, the injection pressure is 95mpa, the molding cycle is 21s, and the screw rotation speed is 60 r / min.

[0019] In step 3), when spraying, the distance between the spray gun nozzle and the sprayed surface is 20-30 cm.

[0020] In step 3), the baking and drying is carried out at 70℃ for 4-4.5h.

[0021] The application has the following advantages: (1) the frame is made of imported TR material and adds mineral that generates negative ions, i.e. hexagonal stone. The main components of hexagonal stone are CaCO3, SiO2, and complex compound of variable valence metal Fe, a small amount of TiO2, and trace elements such as germanium, calcium, magnesium, sodium, potassium, iron, selenium, zinc and other nutrients essential for the human body. The variable valence metal Fe is easy to undergo oxidation-reduction reaction and combines with water molecules in the environment to form a large number of negative ions. Negative ions are confirmed to be an effective means of killing bacteria and purifying air. The mechanism mainly lies in that after the negative ions combine with bacteria, the bacteria change structure or energy transfer, leading to the death of the bacteria, and finally sinking to the ground. The negative particles in the air increase the oxygen content in the blood, which is beneficial to blood oxygen transport, absorption and utilization, and has the effect of promoting human metabolism, enhancing human function and regulating the balance of body function. Keeping the eyes in a fresh, clean and oxygenated environment for a long time can effectively relieve eye dryness, stinging and eye fatigue. (2) The frame body surface is sprayed with a mixture of bright gold oil material and water-soluble antibacterial silver ions. The frame with silver ions has the active defense function against bacteria and further directly inhibits the invasion of bacteria on the skin. DETAILED DESCRIPTION

[0023] Example 1

[0024] The balance point of the toughness and negative ion release value of the frame material is found by screening the best weight ratio of TR plastic titanium and nano hexagonal stone in the frame material

[0025] (1) TR plastic titanium and nano hexagonal stone are configured into frame material according to the weight ratio of 0.8:0.2, then the frame material is stirred for about 30 minutes by a dust-free stirrer, and after uniform stirring, the granulation process is carried out. The granulator selects a single screw extruder with a diameter of 65 mm, the kneading time is 510 min, the extrusion rod temperature is 190℃, 200℃, 195℃, 195℃ in turn, then the granulated frame material is poured into a drying machine, and baked at 90℃ for 3 h; finally, the baked frame material is poured into the injection machine barrel of the frame mold, and the temperature parameters of the injection machine are set as follows: feeding section 235℃, middle section 240℃, discharge section 245℃, nozzle 255℃, mold temperature 90℃, injection pressure 95mpa, molding cycle 21s, screw speed 60 r / min, through injection molding, the negative ion frame body is obtained.

[0026] The experimental results are as follows: the frame surface has whitening and fogging, and the frame is peeled off like a machine. The mechanical fatigue test of the frame shows that the frame is not broken, which meets the product standard requirements. The analysis shows that the toughness of the TR plastic titanium material is changed due to the excessive addition of negative ion material, which causes the frame to break and peel off like a machine. The frame surface has whitening and fogging due to incomplete drying of the material. The negative ion release test result is 1350, which meets the expected target requirements.

[0027] (2) TR plastic titanium and nano six-ring stone are configured into a frame material according to a weight ratio of 0.9:0.1, and then the frame material is stirred for about 30 minutes by a dust-free stirrer. After uniform stirring, the granulation process is carried out. A single screw extruder with a diameter of 65 mm is selected for the granulator, the kneading time is 510 min, and the extrusion rod temperature is 195℃, 200℃, 195℃, 195℃ in turn. Then the granulated frame material is poured into a drying machine and baked at 90℃ for 4 h. Finally, the baked frame material is poured into the injection machine barrel of the spectacle frame mold, and the temperature parameters of the injection machine are set as follows: the feeding section is 235℃, the middle section is 240℃, the discharge section is 245℃, the nozzle is 255℃, the mold temperature is 90℃, the injection pressure is 95mpa, the molding cycle is 21 s, and the screw speed is 60 r / min. Through injection molding, a negative ion spectacle frame is obtained.

[0028] The experimental results are as follows: the frame surface has whitening and fogging. The mechanical fatigue test of the frame shows that the frame is not broken, which meets the product standard requirements. The analysis shows that the frame surface has whitening and fogging due to incomplete drying of the material. The negative ion release test result is 930, which does not meet the expected target requirements. The analysis shows that the negative ion raw material is not added enough.

[0029] (3) TR plastic titanium and nano six-ring stone are configured into a frame material according to a weight ratio of 0.84:0.16, and then the frame material is stirred for about 30 minutes by a dust-free stirrer. After uniform stirring, the granulation process is carried out. A single screw extruder with a diameter of 65 mm is selected for the granulator, the kneading time is 510 min, and the extrusion rod temperature is 195℃, 200℃, 195℃, 195℃ in turn. Then the granulated frame material is poured into a drying machine and baked at 95℃ for 4 h. Finally, the baked frame material is poured into the injection machine barrel of the spectacle frame mold, and the temperature parameters of the injection machine are set as follows: the feeding section is 235℃, the middle section is 240℃, the discharge section is 245℃, the nozzle is 255℃, the mold temperature is 90℃, the injection pressure is 95mpa, the molding cycle is 21 s, and the screw speed is 60 r / min. Through injection molding, a negative ion spectacle frame is obtained.

[0030] The experimental results: the surface of the frame body has no obvious grain crystallization, no whitening and fogging, no peeling phenomenon, which meets the product technical requirements. The frame body is subjected to mechanical fatigue detection, and the result is no breakage, which meets the product technical requirements, has super toughness, impact resistance, and wear resistance, and can effectively prevent damage to the eyes and face caused by frame breakage and friction during movement. Due to its unique molecular structure, it has good chemical resistance and is not easy to deform in high temperature environment. The negative ion release test result is about 1200, which meets the expected target requirements.

[0031] In summary, the best weight ratio of TR plastic titanium to nanometer six-ring stone is 0.84:0.16.

[0032] Example 2

[0033] Through the screening of the best weight ratio of bright gold oil and antibacterial silver ions in the mixed paint sprayed on the surface of the frame body, the balance point of the wrapping layer material on the surface of the frame body and the antibacterial efficiency of water-soluble antibacterial silver ions is found.

[0034] (1) Mix the bright gold oil and the antibacterial silver ions according to the weight ratio of 0.85:0.15, mix them evenly, and stir them with a blender for 10 minutes, then stand still for about 15 minutes to eliminate bubbles, then put them into a spray gun for paint spraying process. Spray each surface 3 times in the order of inside first and outside last, the distance between the nozzle and the sprayed surface is appropriate, and finally place the sprayed frame body in an oven and bake at 65 degrees for 3 hours.

[0035] Experimental results: the paint on the surface of the frame body cannot be evenly attached to the frame body, and there are rough stream drooping phenomena. The reason is that too much silver ion is added, causing the paint to be too thin and not enough viscosity.

[0036] (2) Mix the bright gold oil and the antibacterial silver ions according to the weight ratio of 0.9:0.1, mix them evenly, and stir them with a blender for 10 minutes, then stand still for about 15 minutes to eliminate bubbles, then put them into a spray gun for paint spraying process. Spray each surface 3 times in the order of inside first and outside last, the distance between the nozzle and the sprayed surface is appropriate, and finally place the sprayed frame body in an oven and bake at 65 degrees for 3 hours.

[0037] Experimental results: the paint on the surface of the frame body cannot be evenly attached to the frame body, and there are slight stream phenomena. After baking, the paint has peeling phenomenon after wrapping layer adhesion and anti-sweat corrosion detection experiment. The reason is that too much water-based silver ion is added, causing the paint to be too thin and not enough viscosity, and the baking temperature is low, and the paint is not completely cured.

[0038] (3) Mix the bright surface gold oil and the antibacterial silver ion according to the weight ratio of 0.92:0.08, mix them evenly, and fully stir them with a blender for 10 minutes, then stand still for 15 minutes or so to eliminate bubbles, and then put them into a spray gun for paint spraying process. Spray each surface 3 times in the order of inside first and outside last, and the distance between the nozzle and the sprayed surface is preferably 20-30 cm, and finally put the frame body after the spraying into an oven and bake it at 70 degrees for 4 hours.

[0039] Experimental results: The paint body on the frame surface is evenly attached to the frame without flow line phenomenon. After the wrapping layer adhesion and anti-sweat corrosion detection experiment, the paint body does not fall off, which meets the product technical requirements. The frame can achieve effective antibacterial effect after the plastic surface antibacterial test.

[0040] In summary, the best weight ratio of the bright surface gold oil and the antibacterial silver ion is 0.92:0.08.

[0041] Example 3

[0042] Through the selection of the best thickness of the mixed paint sprayed on the surface of the frame, the balance point of the spraying thickness and the negative ion release decay value of the frame is found.

[0043] (1) Mix the bright surface gold oil and the antibacterial silver ion according to the weight ratio of 0.92:0.08, and prepare the mixed paint, then spray the mixed paint on the surface of the frame, and the spraying thickness is about 200 μm.

[0044] Experimental results: After the wrapping layer adhesion and anti-sweat corrosion detection experiment, the paint body does not fall off, which meets the product technical requirements, and the frame can achieve effective antibacterial effect after the plastic surface antibacterial test. The negative ion release check result value is about 850, which does not meet the expected target requirement (target: more than 1000), and is unqualified. The reason is that the thick wrapping layer blocks the negative ion release space, causing the negative ion value to be low.

[0045] (2) Mix the bright surface gold oil and the antibacterial silver ion according to the weight ratio of 0.92:0.08, and prepare the mixed paint, then spray the mixed paint on the surface of the frame, and the spraying thickness is about 130 μm.

[0046] Experimental results: After the wrapping layer adhesion and anti-sweat corrosion detection experiment, the paint body does not fall off, which meets the product technical requirements, and the frame can achieve effective antibacterial effect after the plastic surface antibacterial test. The negative ion release check result value is about 1080, which meets the expected target requirement (1000 or more), and is qualified.

[0047] In summary, the best spraying thickness of the mixed paint on the surface of the frame is 130 μm.
