Composite string course and preparation method thereof

Abstract

The invention provides a preparation method for a composite string course. The preparation method comprises the following steps: S1, putting 15 parts of unsaturated resin, 10 parts of quartz powder and 24 parts of quartz sand into a container and carrying out uniform mixing under stirring with a mixer for 1 to 3 min; S2, adding 0.3 part of a promoter into a material obtained in the step S1, carrying out stirring for 1 to 3 min to realize uniform mixing, then adding 0.7 part of a curing agent and carrying out stirring for 1 to 3 min; S3, pouring the materials mixed in the step S3 into a mold, flatting the materials through scraping, putting the mold in a vacuum chamber and carrying out vacuum-pumping for 30 to 120 s; S4, putting a ceramic chip with a size equal to the size of the mold intothe mold, allowing the ceramic chip to bond with the materials when the materials have undergone vacuum-pumping and are not completely cured and carrying out complete curing molding within 10 min; andS5, after complete curing of a product of the previous step, stacking the product at room temperature for 10 to 24 h, then carrying out curing, then carrying out edging after complete curing, and cutting the product to composite string course blanks of different specifications and different sizes. The composite string course provided by the invention is reasonable in composition, easy to mold andto fuse with different materials, low in price and not prone to deformation, and has good firmness.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a composite waistline and a preparation method thereof. Background technique [0002] The decorative waistline in the prior art is relatively cumbersome to make, which increases the production cost of the enterprise. After the production is completed, it is not easy to fuse with materials of different materials during the installation process, which is extremely inconvenient to use, and it is made The finished product is prone to other changes, its own stability is poor, and it is prone to deformation. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a composite waistline and its preparation method, which has a reasonable structure ratio, easy molding, firmness, and easy fusion with materials of different materials, so that it can meet the work requirements, and the material is relatively It...
