Abstract
The invention relates to a formula for an over-wide chlorinated polyethylene waterproof coiled material and its production method. The production method is characterized in a materials mixing method is used, chlorinated polyethylene and various additives are evenly mixed, a process of milling is carried out through one or a combination of a mixer and a double screw extruder to prepare particles or gum block, then two or more than two sets of single screw extruders is used for providing materials for large mould at two or more than two positions, thereby the over-wide chlorinated polyethylene waterproof coiled material can be extruded. The width of the products can reach 8-10m, and the thickness of the product can reach 1-3mm. The advantage of preparation technology is that a multiple position feeding co-extrusion molding method is used to prepare the over-wide chlorinated polyethylene waterproof coiled material with excellent index of various performances, the production method has the advantages of continuous production, large yield, stable process and low cost, and is suitable for large-scale industrial production, and can be widely applied in bridge concrete surfaces, tunnels, roof coverings, underground passages, methane tanks for water, seepage and moisture resistance engineering.
Description
One, technical field
The present invention relates to a kind of production method of ultra wide chlorinated polyethylene waterproof roll material, belong to polymer processing field.
Two, background technology
Chlorinated polyethylene rubber is the thermoplastic elastomer (TPE) that is prepared through chlorination by high density polyethylene (HDPE), and reaction equation is following:
Or
1
The molecular structure of haloflex is saturated, no unsaturated double-bond, and molecule is stable, has the chlorine atom of segment polarity.So haloflex has advantages such as good compatibility, ozone resistance, hear resistance, weathering aging property, oil resistivity, chemical proofing, low-temperature flexibility, anti-flammability and high fillibility.Another outstanding feature of haloflex is not only can fill various fillers such as calcium carbonate, talcum powder, bentonite, titanium white powder, magnetic etc., and loading is big, can fill the filler of self several times quality.So the waterproof roll cost that haloflex makes is low, hot strength is high, and percentage elongation is big, and the thermal contraction of catching a cold is little, and good elasticity and impermeability are arranged, and is the very high product of a kind of cost performance.
Mostly chlorinated polyethylene waterproof roll in the market is with the haloflex to be base material, is skeleton with glass grid cloth, and width is generally all less than 1.6 meters.Processing method adopts rolling process, and this forming method working (machining) efficiency is low, and poor working environment is unfavorable for the popularization of chlorinated polyethylene waterproof roll.Also have another kind of formula and process for preparing wide chlorinated polyethylene waterproof roll material by extrusion molding method, the width maximum can only reach 4 meters.Other polymer membranes such as polyvinyl chloride, polyethylene waterproof roll etc. have cost high, shortcomings such as resistance to ag(e)ing difference.Polymer modified bituminous waterproof sheet material also adopts rolling process, and working (machining) efficiency is low, and cost is high.
In sum, existing waterproof roll can not have advantages such as ultra width, high-performance, low cost and easy processing concurrently.It is great in constructing amount at bridge concrete bridge floor etc. not suit, and the waterproofing work of construction face width also has the popularization on roofing and the underground waterproof market.
Three, summary of the invention
The objective of the invention is to take the ultra wide chlorinated polyethylene waterproof roll material of multiple spot co-extrusion modling method preparation.It is narrower to be characterized in having solved the conventional waterproof web width, is difficult for once producing width 8-10m, and thickness is the chlorinated polyethylene waterproof roll of 1-3mm.Target of the present invention is realized that by following technical measures wherein said umber is parts by weight except that specified otherwise.The technology of the two light face chlorinated polyethylene waterproof rolls of the ultra wide cut of multiple spot co-extrusion modling method preparation comprises subordinate's step:
1, according to certain weight proportion; In the haloflex base-material, add inorganic filler, fire retardant, reinforcing agent, age resistor, vulcanizing agent, vulcanization aid, antioxidant, plasticizer, lubricant, thickener, colouring agent etc., use the homogenizer high-speed mixing down for 130 ℃.
2, the haloflex compound that mixes is carried out through one or more compound modes of banbury and double screw extruder mixing, granulation or glue piece.
3, the particle that will make or blob of viscose carry out multiple spot (two or more) charging through the single screw extrusion machine more than two or two to large mold; Co-extrusion modling; Cross roll-in light or embossing and prepare a kind of width range at 8-10 rice, thickness is the ultra wide chlorinated polyethylene waterproof roll material of 1-3mm.
The present invention compared with prior art has following characteristics:
It is mixing that the present invention adopts a kind of or compound mode of banbury and double screw extruder to carry out, and makes particle or blob of viscose; Adopt extrusion moulding, have produce continuously, technology controlling and process is good, the products thickness good uniformity, horizontal thickness error can remain on below the 0.2mm; The present invention adopts the single screw extrusion machine more than two or two, and multiple spot (two or more) feed is given mould, and the method for co-extrusion modling can be produced the waterproof roll that width is a 8-10 rice.
