Embodiment 1

[0012] A method for composite molding of spliced ​​panels, the following steps are adopted: a, decomposing tremolite and diopside into thin slices with a thickness of 5-10 mm by sawing equipment or splitting equipment as surface spliced ​​panels; b, then 5- 80-mesh mineral sand, 230-800-mesh mineral-filled stone powder and resin glue are mixed into a matrix mixture at a mass-to-number ratio of 63:12:6, and the mineral-filled stone powder and resin glue are mixed at a mass ratio of 1:1. The ratio of parts is made into gap filler; c. Then arrange the surface splicing boards on the steel formwork first, and then use the gap filler to paint the cracked board surface with a thickness of 0.5mm, and then apply the matrix mixture with a thickness of 6mm. Covering as a whole; d. Vertically stack 6 templates for laying materials, and use the compression spring set on the frame of the steel template for interlayer support. The reciprocating lifting frequency of Hz and the lower vibration...

Abstract

The invention particularly discloses a method for splice plate composite molding, and solves the problems that when the existing mineral, such as tremolite, quartzose jade and the like, is molded, the cost is high, the environmental performance is poor and buckling deformation occurs. The method comprises the following steps: a, decomposing at least one of tremolite, diopside, quartzose jade, skarn and serpentine into surface layer splice plates, b, then stirring mineral sand, mineral filling rock flour and resin glue solution into matrix mixture, and blending the mineral filling rock flour and the resin glue solution into gap filling material, c, arranging the surface layer splice plates, brushing gap boards through the gap filling material, and then covering the matrix mixture on the gap filling material, d, performing vacuum pumping, and then performing dual vibration through a pressing plate and lower part vibrating frequency, e, performing heating till thermocuring is accomplished, then lifting up the pressing plate, and f, finally performing surface rough grinding and accurate grinding machining to surface layer splice boards. The method greatly reduces the cost, and also eradicates the phenomenon of buckling deformation.

Description

technical field [0001] The invention relates to a molding method of building stones, in particular to a composite molding method of spliced ​​panels. Background technique [0002] The processing of natural slabs in the stone industry mainly focuses on the production of granite and marble-like minerals with a certain size and no serious cracks, which are sawed first and then ground. approach to heterogeneous polymerization processing. [0003] In the northwest and central regions of my country, there are huge reserves of tremolite, diopside and quartz stone jade minerals, but there are serious problems of joints and fissures, and it is difficult to form a production scale by using natural plate processing technology. It is also difficult to produce a higher market price by crushing all synthetic granite into fine sand and then synthesizing it. [0004] At present, the development of spliced ​​composite panels is based on the vacuum equipment of solid surface materials and ar...
