Embodiment 1

[0021] A flame-retardant PVC adhesive, its components and mass ratio are: PVC: 40%; calcium carbonate: 15%; flame retardant: 10%; cold-resistant plasticizer DSP: 15%; three salts: 1.5% %; disalt: 1.5%; lead stearate: 2%; chlorinated paraffin: 15%.

Embodiment 2

[0022] Embodiment 2: a kind of preparation technology of flame-retardant PVC adhesive glue, the steps are as follows:

[0023] 1), according to the mass ratio to select the appropriate measurement of raw materials, the raw materials are as follows: PVC, calcium carbonate, flame retardant, cold-resistant plasticizer DSP, triple salt, di-salt, lead stearate, chlorinated paraffin.

[0024] 2) Add the above-mentioned raw materials into the batching mixing tank, and heat to an appropriate temperature for sufficient stirring. In this step, the heating temperature is 80-120°C.

[0025] 3) After the raw materials in the mixing tank come out, they enter the colloid mill to ensure that the raw materials are pure, hygienic and pollution-free.

[0026] 4), the raw materials from step 3) enter the cooling and stirring tank to make flame-retardant PVC adhesive glue.

[0027] 5), the waterproof coating that comes out in step 4) carries out inspection and test, packs and puts in storage, an...

Abstract

The invention discloses flame retardant polyvinyl chloride (PVC) bonding glue and a preparation method thereof. The bonding glue comprises the following components in percentage by mass: 30-50% of PVC, 10-20% of calcium carbonate, 5-15% of flame retardant, 15-25% of cold-resistant plasticizer DSP, 1-2% of trisalt, 1-2% of basalt, 1-3% of lead stearate and 10-20% of chlorinated paraffin. The bonding glue is convenient to construct, is excellent in aging resistance and has both plasticity and high elasticity, and meanwhile the flame retardant PVC bonding glue disclosed by the invention can achieve rapid bonding, and is good in flame retardant function and aging resistance, good in quakeproof and insulating properties, very high in elasticity and waterproof and air-locked.

Description

technical field [0001] The invention belongs to the field of adhesive glue for waterproofing, and in particular relates to a flame-retardant PVC adhesive glue. Background technique [0002] At present, there are many varieties in the field of adhesive materials, especially more adhesives for waterproof materials. There are many common shortcomings in these adhesives, namely: [0003] 1. Since the raw materials are organic resin, rubber, solvent and additives, it is a very good flammable material, which will burn immediately when exposed to fire, and it is very easy to cause a fire. [0004] 2. It can be seen from the existing adhesive products and raw material formulas that in order to reduce the raw material cost of the product or because the technology cannot meet the requirements, the manufacturer does not add any flame retardant ingredients to almost all products, and it is not seen in the market. To the adhesive marked "flame retardant". [0005] 3. Poor aging resist...
