TABLE 2 examination results of abrasion resistant gel coats prepared in examples 1 to 5 and comparative examples 1 to 6
As can be seen from the data in table 2, the sliding chute prepared according to the embodiment 1-5 has smooth surface, small roughness, smooth and easy passage of goods, good silencing effect, small friction coefficient, good wear resistance, strong adhesive force between the gel coat resin and the glass fiber reinforced plastic, and large bending strength, and is not easy to crack when the glass fiber reinforced plastic is bent, small wear rate when objects circulate, longer service life of the working surface, low maintenance frequency of the sliding chute, high impact strength, and uneasy deformation of the objects under high-frequency impact collision.
Comparative example 1 because no graphite is added to the lubricant, the sliding chute made of the glass fiber reinforced plastic coated with the gel coat resin prepared in comparative example 1 has increased roughness and increased friction coefficient, and the adhesive force between the gel coat resin and the glass fiber reinforced plastic is reduced, so that the wear rate is increased and the wear resistance is poor, which indicates that the friction coefficient of the sliding chute can be reduced by adding the graphite, the smoothness of the sliding chute is increased, the adhesive force between the gel coat resin and the glass fiber reinforced plastic is improved, the wear rate of the sliding chute is reduced, and the wear resistance of the sliding chute is enhanced.
In the comparative example 2, because the PTFE micro powder is not added into the lubricant, the roughness of the sliding chute prepared in the comparative example 2 is increased, the friction coefficient is increased, the adhesive force of the gel coat resin is reduced, the wear rate of the sliding chute is increased, and the wear resistance is poor, which shows that the addition of the PTFE micro powder can increase the smoothness of the surface of the sliding chute, reduce the wear amount of the sliding chute, increase the adhesive force between the gel coat resin and the glass fiber reinforced plastic, and increase the wear resistance of the sliding chute.
Comparative example 3 since the mass ratio of graphite to PTFE fine powder in the lubricant was only 1:0.5, the surface roughness of the chute prepared in preparation example 3 was significantly increased, the smoothness was decreased, the wear rate was increased, the adhesion was decreased, and the wear resistance was deteriorated as compared with examples 1 to 5, which indicates that the smoothness and wear resistance of the chute could be significantly enhanced by using graphite and PTFE fine powder having a mass ratio of 1 (1-4) as the lubricant.
Comparative example 4 since the mass ratio of graphite to PTFE micropowder in the lubricant was 1:4.5, the run channel surface had a relatively low roughness, a low coefficient of dynamic friction and a low coefficient of static friction, a good smoothness, but a poor abrasion resistance, and the glass fiber reinforced plastic substrate was exposed only by grinding 55800 times, it was shown that excessive addition of PTFE micropowder reduced run channel friction, but reduced run channel abrasion resistance, and reduced its service life.
In comparative example 5, the usage amount of molybdenum disulfide in the lubricant is 1kg, so that the usage amount is small, the sliding chute prepared in comparative example 5 is large in roughness, poor in smoothness and wear resistance, large in wear rate and short in service life, and therefore, the fact that the roughness and smoothness of the sliding chute are affected by reducing the usage amount of molybdenum disulfide is shown, and the wear resistance and service life of the sliding chute are reduced.
Comparative example 6 since the amount of molybdenum disulfide used in the lubricant was 5kg and the amount used was large, the run channel prepared in comparative example 6 had a small roughness and good smoothness, but had a large wear rate and poor wear resistance, and the adhesion was only 3B, indicating that increasing the amount of molybdenum disulfide used reduced the coefficient of friction of the run channel and increased the smoothness, but had a reduced wear resistance, an increased wear rate, and a reduced adhesion to the glass fiber reinforced plastic substrate.
Comparative example 7 because the wear-resistant gel coat only contains 3kg of molybdenum disulfide and 100kg of m-phenyl neopentyl glycol type gel coat, and graphite powder and PTFE micropowder are not added, the friction coefficient of the chute prepared by the comparative example 7 is reduced, the smoothness is good, but the wear rate of the chute is high, and the wear resistance is poor, which shows that the friction coefficient can be reduced and the smoothness can be improved by only adding molybdenum disulfide, but the wear resistance of the chute can not be improved.
Comparative example 8 since the wear-resistant gel coat was made of 3kg of silica, which can fill the pores in the gel coat resin and increase the hardness of the run, and 100kg of the m-phenyl neopentyl glycol type gel coat, the run made of comparative example 8, which is large in both roughness and wear rate, shows that the use of silica as a wear-resistant component has less influence on the smoothness and wear resistance of the run.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
