Problems solved by technology

After the unremitting efforts of countless scientific workers, new waterproof and thermal insulation products emerge in endlessly, but they are either poor in performance and short in service life, or they are expensive and seriously polluted the environment. Thermal insulation materials mainly include linoleum, ointment, waterproof glue, waterproof powder, etc. Linoleum, ointment, and waterproof glue are prone to aging and cracking, and the waterproof and heat preservation cannot last. Waterproof powder has better waterproof and heat preservation performance, but the cost of raw materials is too high. The product is expensive, the investment in production equipment is large, the production process is complex, the production cycle is long, and the construction conditions are harsh
The above products have caused pollution to the surrounding environment during processing and construction.
Some products will lose product performance due to harsh natural climate

Embodiment Construction

[0013] First, the yellow sand is screened by a screening machine, and then 700 grams of mixed yellow sand with a diameter of 0.10mm-2.00mm is sent to the dryer for drying, of which the yellow sand 200 with a diameter of 0.10mm-1.00mm has a diameter of 1.00mm-1.50mm 200 parts by weight of yellow sand with a diameter of 1.50mm-2.00mm; 300 parts by weight of yellow sand with a diameter of 1.50mm-2.00mm; the moisture content in the dried mixed yellow sand is reduced to 12%, and then preheated by a constant temperature machine, and 70 parts by weight of paraffin wax is added , 80 parts by weight of stearic acid are mixed and stirred, and 10 parts by weight of alum, paraffin, stearic acid, and alum are melted by heating, and the yellow sand particles are evenly wrapped. The processed yellow sand is fully expanded under the effect of thermal expansion and contraction. It is mixed with other materials and melted into one with other ingredients; then at a temperature of 80 ℃ constant tempe...

Abstract

The process of producing waterproof heat insulating material with sand as main material includes sieving yellow sand, adding paraffin, stearic aid, alum and other additives, and heating to form the waterproof heat insulating material. The waterproof heat insulating material is set in the bottom or the surface of building to form one isolating film with excellent watertight performance and high durability.

Description

Technical field [0001] The invention belongs to the technical field of production methods for waterproof materials, and is a method for producing waterproof and temperature-insulating materials. Background technique [0002] For a long time, desert water preservation, industrial and civil buildings and facilities, roof leakage, and ground moisture prevention have long been a worldwide problem that has plagued mankind. As early as the early 1950s, well-known scholars around the world have successively put forward the idea of ​​developing new waterproof and temperature-insulating materials, aiming to avoid thermal expansion and contraction, deformation of the base layer, and cracks on the waterproof layer. Through the unremitting efforts of countless scientific workers, new waterproof and thermal insulation products are emerging in endlessly, but either they have poor performance, short service life, expensive price, and serious environmental pollution. Currently, they solve the pr...
