Problems solved by technology

[0002] Polyethylene polypropylene fiber waterproofing membrane has developed rapidly since it was successfully developed in 1989. At present, the adhesives used for polyethylene polypropylene fiber waterproofing membrane are all cement-based adhesives, which are rigid materials, and the bonding of lap joints is also used. Material bonding, when the base layer is deformed, the rigid lapping edge adhesive is easy to crack, resulting in leakage at the lapping edge of the polyethylene polypropylene fiber waterproofing membrane, which leads to the failure of the entire waterproofing project

Embodiment 1

[0045] Measure 30 parts of cement, 15 parts of heavy calcium, 40 parts of quartz powder, 6 parts of water-retaining agent, and 9 parts of thickener, respectively, and then add them to the mixing tank for mixing and stirring. , and then 50 parts of 400 emulsion, 35 parts of 707 emulsion, 13 parts of water, and 2 parts of defoamer were measured respectively, and then added to the mixing tank with blades for stirring. The stirring time was 30-40min. After stirring for 20-30min Add defoamer. After fully stirring, a liquid material is obtained. At the construction site, the liquid material and the powder material are stirred evenly at a ratio of 1:3 to obtain a flexible adhesive for polyethylene polypropylene fiber waterproofing membrane.

Embodiment 2

[0047] Measure 35 parts of cement, 10 parts of heavy calcium, 38 parts of quartz powder, 7 parts of water-retaining agent, and 10 parts of thickener, respectively, and add them into the mixing tank for mixing and stirring. , and then 55 parts of 400 emulsion, 30 parts of 707 emulsion, 14 parts of water, and 1 part of defoamer were measured respectively, and then added to the stirring tank with blades for stirring. The stirring time was 30-40min. After stirring for 20-30min Add defoamer. After fully stirring, a liquid material is obtained. At the construction site, the liquid material and the powder material are stirred evenly at a ratio of 1:3 to obtain a flexible adhesive for polyethylene polypropylene fiber waterproofing membrane.

Embodiment 3

[0049] Measure 40 parts of cement, 20 parts of heavy calcium, 30 parts of quartz powder, 4 parts of water-retaining agent, and 6 parts of thickener, respectively, and add them into the mixing tank for mixing and stirring. , and then 55 parts of 400 emulsion, 30 parts of 707 emulsion, 14 parts of water, and 1 part of defoamer were measured respectively, and 14 parts of 400 emulsion, 707 emulsion and water were added to the stirring tank with paddle blades for stirring. The stirring time 30-40min, add defoamer after stirring for 20-30min. After fully stirring, a liquid material is obtained. At the construction site, the liquid material and the powder material are stirred evenly at a ratio of 1:3 to obtain a flexible adhesive for polyethylene polypropylene fiber waterproofing membrane.

Abstract

The invention provides a flexible adhesive for polyethylene polypropylene fiber waterproofing membrane and a preparation method thereof. The flexible adhesive includes powder and liquid, and the powder includes the following raw materials in parts by weight , 25-45 parts of cement, 5-25 parts of heavy calcium, 25-45 parts of quartz powder, 2-10 parts of water-retaining agent, 4-12 parts of thickener; liquid material, including the following raw materials in parts by weight, acrylic emulsion 70-100 parts, 5-25 parts of water, 0.5-5 parts of defoamer; the liquid material and the powder are mixed according to the weight ratio of 1: (1-6), and a kind of waterproofing method for polyethylene polypropylene fibers provided by the invention The flexible adhesive of the membrane overcomes the traditional polyethylene polypropylene fiber waterproof membrane adhesive, which is a rigid material, and it is easy to crack when used to bond the polyethylene polypropylene fiber lap seam, which affects the waterproof effect of the polyethylene polypropylene fiber waterproof membrane.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, and in particular relates to a flexible adhesive for polyethylene polypropylene fiber waterproof coiled material and a preparation method. Background technique [0002] Polyethylene polypropylene fiber waterproofing membrane has developed rapidly since it was successfully developed in 1989. At present, the adhesives used for polyethylene polypropylene fiber waterproofing membrane are all cement-based adhesives, which are rigid materials, and the bonding of lap joints is also used. Material bonding, when the base layer is deformed, the rigid lapping edge adhesive is easy to crack, resulting in leakage at the lapping edge of the polyethylene polypropylene waterproofing membrane, which leads to the failure of the entire waterproofing project. Contents of the invention [0003] In view of this, the present invention aims to propose a flexible adhesive for polyethylene polyprop...
