s2, taking 1 part of cement, 1 part of expanded perlite, 1 part of straw chopped fiber, 1 part of medium and coarse yellow sand, 0.1 part of coagulant, 0.1 part of waterproof agent and 1 part of water, stirring and mixing to form slurry 1, taking 1 part of cement, 3 parts of medium and coarse yellow sand, 0.1 part of coagulant and 0.1 part of waterproof agent, and stirring and mixing to form slurry 2;
s3, putting 2 steel wire meshes with matched sizes with the core board into different molds with male ear fans and female sills, then pouring mixed slurry 1 in the middle, pouring mixed slurry 2 with the width of 100mm around, making a first panel and a second panel with the thickness of 20mm in the middle and the width of 50mm around and the thickness of 10mm around, naturally curing for 15-28 days, and finally pasting the first panel and the second panel on the two sides of the core board by cement paste for curing and setting, thus obtaining the light energy-saving composite wallboard with excellent overall performance and reusability in assembly construction.
2. The prefabricated reusable composite wallboard of claim 1, wherein the straw chopped fiber is 1-6 parts, lime is 0-2 parts, cement is 0.5-3 parts, yellow sand is 1-5 parts, coagulant is 0-2 parts, and water repellent is 0-2 parts.
3. The prefabricated construction reusable composite wallboard according to claim 1, wherein the straw is fibrous, the linear length of the straw is 20-25mm, the cement is 325 Portland cement, and the yellow sand is medium coarse type.
4. The prefabricated construction reusable composite wall panel according to claim 1, wherein the first and second panels in step S3 are each 5-40mm thick, 5-20mm wide and 5-20mm thick with respect to the surrounding ear and notch ridge.
5. The prefabricated construction reusable composite wall panel according to claim 4, wherein in step S3, two ends of the first panel are extended with 50mm wide and 10mm thick ear fans, one end is inserted with 50mm wide and 10mm deep right-angled concave ridges, one end of the second panel is inserted with 50mm wide and 10mm deep right-angled concave ridges, and the first and second panel ear fans and concave ridges form a male-female combination when the two panels are assembled up, down, left and right, and the wall panel rim is locked and fixed by a special screw.
6. The prefabricated reusable composite wall panel of claim 1, wherein the recessed sill platforms on both sides of the second panel are notched.
7. An assembled construction reusable composite wall panel according to claim 1 wherein the core has an array of holes therein, the holes having a diameter of 20 to 100 mm.
