The invention is realized by the following steps:
the engine compartment heat insulation pad comprises an outer layer and a heat insulation layer, wherein the outer layer is coated on the outer side of the heat insulation layer, and the heat insulation layer is made of an environment-friendly material.
According to the engine compartment heat insulation pad provided by the invention, as the heat insulation layer of the main body is made of the environment-friendly material, after the service cycle of a system and equipment provided with the engine is expired and scrapped, the engine compartment heat insulation pad can be rapidly treated without pollution, and can be applied to other occasions even after simple treatment, so that the problem of pollution caused by the engine heat insulation pad after scrapping of equipment such as automobiles and ships is effectively solved.
Further, the thermal insulation layer comprises basalt fiber prepreg cloth. The technical effects are as follows: the basalt fiber is a novel inorganic environment-friendly green high-performance fiber material and is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, titanium dioxide and the like. The basalt continuous fiber has high strength, and also has various excellent performances of electrical insulation, corrosion resistance, high temperature resistance and the like. In addition, the production process of the basalt fiber determines that the basalt fiber produces less waste and causes little pollution to the environment, and the product can be directly stored in the environment after being discarded or used as a material of other products after being crushed without any harm to the environment, so the basalt fiber is a genuine green and environment-friendly material. In addition, the basalt fiber material has good heat insulation and sound absorption performance. The basalt fiber material can be made into basalt fiber prepreg cloth with the thickness of 0.2 mm-0.4 mm for hot press molding. Optionally, such environmentally friendly materials may also include bio-polyesters, bio-fibers, or polylactic acid, among others.
Further, the outer layer comprises an aluminum foil. The technical effects are as follows: compared with materials such as plastics and the like, the aluminum foil material has no toxicity or special smell, belongs to a green product and meets the requirement of environmental protection standard. In addition, the aluminum foil is low in price, simple and convenient to manufacture and good in heat insulation performance. And the aluminum foil material is soft in texture and good in ductility, and the rolled sheet can assist the forming of the heat insulation layer and improve the heat and sound insulation effect of the engine compartment heat insulation pad. Optionally, the outer layer may also be made of non-woven fabric according to actual needs.
A method of manufacturing an engine compartment insulation blanket comprising the steps of:

In order to ensure that the thermal insulation layer has more excellent thermal insulation performance under the premise of having sufficient strength, the duration of the hot press molding is set to be between 80 seconds and 90 seconds, and is preferably about 85 seconds.
Further, the outer layer is attached to the upper surface and the lower surface of the heat insulation layer through a hot press molding process. The technical effects are as follows: similarly, when the outer layer is made of aluminum foil, the hot-press forming process is more reasonable. In addition, the engine compartment heat insulation pad needs to be cut and shaped after being hot-pressed and cooled, so that the outer layer only needs to be attached to the upper surface and the lower surface of the outer layer in a hot-pressing mode.
Further, the time period for hot press forming the outer layer is between 15 seconds and 25 seconds. The technical effects are as follows: since the preferred thickness of the aluminum foil is between 0.05 mm and 0.1 mm, the hot pressing time of the outer layer is set in the above-mentioned interval, preferably 20 seconds, according to practical production experience, in order to ensure the bonding firmness of the hot pressing and the optimal fixing effect of the aluminum foil.

Further, the engine compartment heat insulation pad is cut and formed by a water jet cutter. The technical effects are as follows: the heat generated by the water jet can be taken away by water flow in the cutting process, and the thermal deformation between the outer layer and the thermal insulation layer due to the cutting process is not easy to cause.
Further, the water cutting pressure of the water knife for cutting the engine compartment heat insulation pad is 40000psi to 50000 psi. The technical effects are as follows: the water jet cutting pressure is preferably set in the above-mentioned range, particularly preferably around 45000psi, depending on the material and thickness of the heat insulating layer and the material and thickness of the outer layer.
