Technical Field
[0001] The utility model relates to the technical field of profiles, in particular to a profile. Background Art
[0002] Most of the existing thermosetting profiles are used outdoors, so they need to be sprayed on the surface, such as spraying paint, to extend their service life. This method has the following disadvantages:
[0003] Thermosetting profile spray painting process is long and inefficient, which increases the production cost of profiles. The spray painting process is as follows: grinding the surface release agent, removing surface dust, spraying primer, curing, spraying topcoat, curing, and finally obtaining the profile, which makes the processing cycle long and inefficient. In addition, spray painting requires a large production site with a lot of dust, which is not friendly to production personnel.
[0004] Therefore, how to provide a profile that can avoid the above-mentioned disadvantages has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] A profile includes an inner profile which is thermosetting, and an outer covering layer which matches the overall outer shape of the inner profile and is thermoplastic, and covers the overall outer side of the inner profile.
[0007] Preferably, the inner layer profile is solidified by a reinforcement and a matrix, the reinforcement is at least one of glass fiber, carbon fiber, basalt, and Kevlar fiber, and the matrix is at least one of polyester, polyurethane, epoxy, phenolic, and dicyclopentadiene.
[0008] Preferably, the reinforcement comprises an inner layer, a continuous fiber reinforcement layer and an outer layer which are arranged in sequence from the inside to the outside, the inner layer is composed of one or more of glass fiber gingham cloth, warp knitted cloth, seam edge felt and composite felt, the continuous fiber reinforcement layer is made of glass fiber, and the outer layer is composed of one or more of glass fiber gingham cloth, warp knitted cloth, seam edge felt and composite felt.
[0009] Preferably, the outer coating layer comprises at least one of PVC, ASA, PMMA, PE, ABS, PC, and PET.

[0015] Thermosetting materials exert their strength performance, and the outer coating layer is made of thermoplastic materials, which can save the spraying process; the cost is reduced by at least 65%, and the production efficiency is increased by 3-4 times. And the outer coating layer plays the advantages of strong UV resistance and low gap rate, protecting the inner profile from UV and water damage. The outer coating layer is outside the profile, and takes advantage of its own large shrinkage rate. After cooling, the two are combined into one by shrinkage to generate a specific profile.
