Problems solved by technology

[0003] Since the formula of the traditional root puncture-resistant waterproof membrane does not contain anti-impact damage and chemical corrosion resistance ingredients, it cannot fully meet the requirements of the building planting system. When it is used for a long time, it is easy to be penetrated by the root tip of the plant, resulting in building damage and leakage. , directly lead to the failure of the "building planting and greening" system

Embodiment 1

[0024] An enhanced root puncture-resistant waterproof membrane, calculated in parts by weight, including 3 parts of flame retardant FR-301, 16 parts of migration-resistant plasticizer, 70 parts of polyvinyl chloride resin, and 5 parts of epoxy soybean oil , 3 parts of di-salt lead phosphite, 3 parts of tri-salt lead phosphite, 4.5 parts of E-881 modified vinyl acetate copolymer resin and 3 parts of epoxy resin, including filament polyester cloth and root-blocking copper base, The content of the filament polyester cloth is 800g / m 2 .

[0025] According to the proportioning relationship calculated according to the weight parts of the above-mentioned material components, the steps of the production process of the enhanced root-resistant puncture-resistant waterproof membrane according to the present invention are as follows:

[0026] Step 1: Calculated by weight, 3 parts of flame retardant, 16 parts of anti-migration plasticizer, 70 parts of polyvinyl chloride resin, 5 parts of ...

Embodiment 2

[0035] On the basis of Example 1, the number of parts of the anti-migration plasticizer in the waterproof membrane is changed, and on the premise that other parameters remain unchanged, the production process described in Example 1 is still used to produce the waterproof membrane. Parts calculation, the migration-resistant plasticizer in the homogeneous layer 4 described in Example 2 is 15 parts.

Embodiment 3

[0037] On the basis of Example 1, the number of parts of the anti-migration plasticizer in the waterproof membrane is changed, and on the premise that other parameters remain unchanged, the production process described in Example 1 is still used to produce the waterproof membrane. Parts calculation, the anti-migration plasticizer in the homogeneous layer 4 described in embodiment 3 is 10 parts.

Abstract

The invention provides an enhanced root puncture-resistant waterproof membrane, which comprises 2-5 parts of flame retardant, 15-20 parts of anti-migration plasticizer, 60-75 parts of polyvinyl chloride resin, epoxy 2-8 parts of soybean oil, 1-5 parts of di-salt lead phosphite, 1-5 parts of tri-salt lead phosphite, 2-8 parts of E-881 modified vinyl acetate copolymer resin and 1-5 parts of epoxy resin. The invention has strong impact resistance and corrosion resistance, and can meet the current system requirements for planting vegetation in buildings. It is not easy to be penetrated by plant root tips during use, and has a good waterproof effect. , no pollution to the environment, uniform texture and long life.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to an enhanced root puncture-resistant waterproofing membrane and a production process thereof. Background technique [0002] Planting roofs are generally composed of multiple technical structures such as planting, waterproofing, water drainage, thermal insulation, etc. Among them, waterproofing is particularly important. Planting projects require waterproof materials to be waterproof and have root puncture resistance at the same time, so as to prevent plant roots from damaging the waterproof layer. , Insulation layer to protect the safety of the whole project, while the waterproof material should also ensure the normal growth of plants while blocking the roots. [0003] Since the formula of the traditional root puncture-resistant waterproof membrane does not contain anti-impact damage and chemical corrosion resistance ingredients, it cannot fully meet the requirements of the ...
