Problems solved by technology
[0003] However, the existing sodium-based bentonite waterproof blankets have the following problems during needle punching and winding. a. When the traditional sodium-based bentonite waterproof blankets are needle-punched, because the sodium-based bentonite waterproof blankets are not stably pressed before needle punching The operation makes the sodium-based bentonite waterproof blanket loosen during needle punching, which reduces the production quality of the sodium-based bentonite waterproof blanket; The bentonite-based waterproof blanket often loosens during rolling, and needs to be re-rolled, which reduces the rolling efficiency and quality of the sodium-based bentonite waterproof blanket

Embodiment Construction
[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0038] Such as Figure 1 to Figure 11 Shown, a kind of sodium bentonite waterproof blanket manufacturing process mainly includes the following steps:
[0039] Step 1, material preparation, prepare the sodium bentonite mixture, non-woven geotextile and plastic flat wire woven geotextile required for the production of sodium bentonite waterproof blanket;
[0040] Step 2, spreading and compounding, spread the sodium-based bentonite mixture prepared in step 1 evenly on the non-woven geotextile prepared in step 1, and spread the plastic flat wire woven geotextile on the sodium-based bentonite mixture prepared in step 1. On the base bentonite mixture, a composite waterproof blanket that is spread and compounded is obtained;
[0041] Step 3: Acupuncture ...

The invention relates to a sodium bentonite waterproof blanket manufacturing and processing technology which mainly comprises the following steps of material preparation, spreading and compounding, needling operation and other procedures, and used waterproof blanket needling equipment comprises a bottom plate, an extrusion device, a needling device, a clamping device and a winding device. The problems existing in needling and rolling of an existing sodium bentonite waterproof blanket can be solved, a, when a traditional sodium bentonite waterproof blanket is needled, due to the fact that the sodium bentonite waterproof blanket is not subjected to stable abutting operation before needling, the sodium bentonite waterproof blanket is loosened in the needling process, and the production quality of the sodium bentonite waterproof blanket is reduced; and b, when the existing sodium-based bentonite waterproof blanket is rolled, due to the fact that no stable abutting operation exists, the sodium-based bentonite waterproof blanket is prone to loosening when rolled, rolling operation needs to be conducted again, and the rolling efficiency and quality of the sodium-based bentonite waterproof blanket are reduced.
Description
technical field [0001] The invention relates to the technical field of production and manufacture of waterproof blankets, in particular to a manufacturing process for sodium-based bentonite waterproof blankets. Background technique [0002] Sodium-based bentonite waterproof blanket is non-toxic and environmentally friendly, and is widely used. It can be used in underground anti-seepage and waterproof constructions such as roads, railways, and water conservancy. It is especially suitable for waterproof and anti-seepage projects with concrete structures. It is made of highly expansive sodium-based Bentonite is filled between the special composite geotextile and non-woven fabric, and the sodium-based bentonite is fixed between the special composite geotextile and non-woven fabric by needle punching. [0003] However, the existing sodium-based bentonite waterproof blankets have the following problems during needle punching and winding. a. When the traditional sodium-based benton...
