Abstract

The present invention discloses a method for coating a reflecting layer on the surface of a bicycle frame. The method is characterized in that firstly, a layer of adhesive with preset thickness and viscosity is coated on a bicycle frame to be coated; then, dry powdered reflecting particles are uniformly spread on the adhesive; after the reflecting particles are arranged in a regular mode, a layer of transparent surface paint is coated on the adhesive. After the method is adopted, the reflecting particles can be uniformly coated on the bicycle frame without generating stacking of the reflecting particles. When the bicycle frame is illuminated by light, the refraction of light rays caused by the stacking of the reflecting particles is avoided, reflected rays are increased, and the reflection effect is enhanced.

Description

Method for coating light-reflection layer on bicycle frame

The present invention relates to metal surface treatment technology, relate to a kind of method for coating light-reflection layer on bicycle frame specifically.

Article with reflecting effect are to install light-reflecting particles within it, and when these article are subjected to light when irradiation, because of incident light can produce reverberation after injecting its light-reflecting particles, these article have had reflecting effect, can improve safe effect.This reflecting coating is widely used in various traffic utensils, as, be arranged in the middle of the road, the application of the reflecting marking in roadside can be guided, driver assistance person's safety traffic, and traffic-police, the cleanup crew then can remind the driver to take in a reef after putting on the vest with reflector layer, Regular Bicycle is not owing to there is the design of car light, so at night by bike the time, the cyclist exists certain danger, so adopt in recent years at cycle frame surface coating reflector layer, after external car light irradiation is to this bicycle, this bicycle can produce reflecting effect and carefully drive to remind the driver, and then can improve the cyclist in security by bike at night.The existing method of the coating reflector layer on the cycle frame surface of Cai Yonging (problem for convenience of explanation; please consult Fig. 1 earlier) be wet shot reflectorised paint 11 and getting on vehicle frame; 11 of this reflectorised paints are to add light-reflecting particles 112 mediations to form in coating 111; behind overbaking; outside this reflectorised paint 11, be coated with again with clear finish 12; this light-reflecting particles 112 is located really; when light shines this vehicle frame 10; to produce reverberation automatically inject the light-reflecting particles 112 of reflectorised paint 11 because of incident light after; though this reflector layer coating process can make cycle frame produce reflecting effect; but remain: because the proportion of light-reflecting particles 112 is heavy than the ratio of coating 111 in following shortcoming; though coating 111 adds at the beginning of the light-reflecting particles 11; this light-reflecting particles 112 is to be the state that is suspended in these coating 111 surfaces; crossed after the several seconds; this light-reflecting particles 112 will sink (please cooperate and consult Fig. 2) because of gravity; after sinking, this light-reflecting particles 112 will produce stratification; and it is stacked to having several (two or three) light-reflecting particles 112 between the end face from these coating 111 bottom surfaces; so; not only there are these light-reflecting particles 112 skewness to exist; and when incident light injects this reflectorised paint 11; because of the result of its reflection spectrum, so also there is the not good shortcoming of reverberation effect through secondary or three refractions.

The objective of the invention is shortcoming, propose a kind of new method for coating light-reflection layer on bicycle frame at above-mentioned coating process existence.

To achieve these goals, the present invention adopts following technical measures: step 1 at first applies the adhesive of one deck predetermined thickness and viscosity on the cycle frame surface that will be coated with; Step 2 evenly scatters the dry-powder-type light-reflecting particles on this layer adhesive again; Step 3, treat light-reflecting particles be arrange regularly after, apply clear finish more thereon.

Replace and originally in coating, add light-reflecting particles and after being in harmonious proportion, be coated on the vehicle frame surface because the present invention adopts adhesive and light-reflecting particles layering to coat the method that applies clear finish behind the cycle frame surface more thereon, apply the method for clear finish again, can make light-reflecting particles be coated on the cycle frame equably, can not produce the stacked of light-reflecting particles, when light shines thereon, light has been avoided the stacked refraction that causes because of light-reflecting particles, increased reflection ray, reflecting effect increases.

Below in conjunction with drawings and Examples, the present invention is described in further detail:

Fig. 1 is the cross-sectional schematic with the reflector layer after the existing method coating.

Fig. 2 is the local enlarged diagram of the reflector layer of Fig. 1.

Fig. 3 is the process blocks schematic diagram of a preferred embodiment of the present invention.

Fig. 4 is for adopting the reflector layer cross-sectional schematic after the inventive method is coated with.

Fig. 5 is the local enlarged diagram of the reflector layer of Fig. 4.

See also Fig. 3 and cooperate shown in Figure 4, at first apply the adhesive 30 of one deck predetermined thickness and viscosity on cycle frame 20 surfaces that will be coated with, in the present embodiment, this adhesive 30 has adopted epoxy resin (transparent resin), in to this transparent epoxy resin viscosity test, we have adopted IWATA board NK-2 type viscosimeter to measure, and measured value was about 10 seconds-12 seconds.

Again dry-powder-type light-reflecting particles 40 is evenly scattered on this layer adhesive 30, in the present embodiment, system is directly scattered light-reflecting particles 40 on adhesive 30 by material-falling hopper (figure does not show), so just can make light-reflecting particles 40 gluing on adhesive 30, light-reflecting particles is regularly to be arranged, treat that predetermined tack time arrives and after overbaking, on adhesive 30, apply clear finish 50 again, can make this light-reflecting particles 40 be subjected to coating also location really fully.

Because light-reflecting particles 40 is all smooth spherical particle, and its proportion is quite heavy, be all the pipe design because of Regular Bicycle vehicle frame 20 again, add the no show still of complete gluing time of adhesive 30, and during this light-reflecting particles 40 of spreading, this cycle frame 20 will be through upset, so this light-reflecting particles 40 is scattered at the beginning of on the adhesive 30, it in fact still can produce upset, almost arrange regularly and can be, treat after the gluing time arrival of adhesive 30, please cooperate consult shown in Figure 5, this light-reflecting particles 40 can be gluing on this adhesive 30, and the 1/3-1/4 of these light-reflecting particles 40 about its diameters is highly gluing on this adhesive 30, because the spherical particle that this light-reflecting particles 40 is smooth shape as previously mentioned, so when second layer light-reflecting particles 40 is stacked in gluing light-reflecting particles 40 tops in adhesive 40, this second layer light-reflecting particles 40 will not understood nature and drop because of there being enough adhesive tensions, and then, gluing light-reflecting particles 40 sticking the putting on cycle frame 20 on adhesive 30 of original ground floor are only arranged, still can be recycled by reclaimer as for not gluing light-reflecting particles, avoid the wasting of resources.So adopted this method, light-reflecting particles 40 almost is regularly to be arranged, the uniformity of its distribution is also quite good, light-reflecting particles 40 does not have stacked situation and produces, so when light shines this cycle frame 20, after its incident light (shown in the imaginary light of Fig. 5) injects light-reflecting particles 40, only can produce reverberation through after the unirefringence.

Above-mentioned description of doing of the present invention and accompanying drawing only are a preferred embodiment.
