In order to achieve the above purpose, the utility model adopts the following technical scheme:

the grinding stone component comprises a prefabricated component, wherein a bottom coating is paved on the prefabricated component, a glass fiber layer is paved on the bottom coating, an aggregate paving layer is paved on the glass fiber layer, and an antifouling layer is coated on the surface of the aggregate paving layer.

Preferably, the base coat is used for the ground coat.

The utility model provides a pair of grindstone component, beneficial effect lies in: the prefabricated member is good in decoration, can be directly installed and used, does not need to be deeply processed again, has a decoration effect after leaving a factory, improves the efficiency of the whole house building, has good mechanical property and chemical property, and is longer in service life compared with a common member.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, the grinding stone component comprises a prefabricated component 1, a bottom coating 2 is paved on the prefabricated component 1, a glass fiber layer 3 is paved on the bottom coating 2, an aggregate spreading layer 4 is paved on the glass fiber layer 3, an antifouling layer 5 is coated on the surface of the aggregate spreading layer 4, and the bottom coating 2 is a bottom coating for a grinding stone.

A method of laying a stone member comprising the steps of:

step one, base layer treatment:

cleaning up sundries on the prefabricated part without oil stains and floating soil;

step two, priming and laying of a glass fiber layer:

selecting a bottom coat for the diamond, uniformly coating and sealing the base layer, wherein the material dosage is 0.3kg per square meter, and paving a glass fiber layer while bottoming; the bottom coat for the diamond adopts resin: the curing agent is prepared from (by weight) bisphenol A diglycidyl ether 128 or 828, bifunctional epoxy active diluent 5-25, defoaming agent 0.1-0.5, polyamide 20-50, modified hexamethylene diamine 10-30, and modified polyether amine 20-40, and is prepared from (by weight) bisphenol A diglycidyl ether 128 or 828, bifunctional epoxy active diluent 5-25, and defoaming agent 0.1-0.5.

The bottom coating has the function of reinforcing the precast concrete component by permeating the precast concrete component, so that the resin and the ground are chemically anchored;

step three, paving an aggregate spreading layer:

paving the uniformly stirred paving material on the ground, measuring a horizontal point by adopting infrared rays in each small paved area, and compacting and smoothing the surface of the paved material by using a trowel; the paving material is a mixture of aggregate and resin, which is prepared according to the ratio of 4:1, the paving thickness is 11-13mm, the using amount of the paving material is 23-25kg per square meter, the aggregate is one or more of quartz stone, marble, granite, glass and ceramic, and the aggregate proportion is as follows:

the resin mixture used was resin: the ratio of the curing agent is 4:1,

wherein the resin proportion is as follows:

the proportion of the curing agent is as follows:

20-70% of modified alicyclic amine

30-50% of modified polyether amine.
