Abstract
A powdery primer for self-adhered waterproof membranes comprises the following components in parts by weight: 70-80 parts of high polymer emulsion powder, 4-5 parts of a thickener, 0.6-0.8 part of a light stabilizer and 3-4 parts of a defoamer. The substances are sequentially put into a container and uniformly stirred to obtain the solid powdery primer applicable to self-adhered waterproof membranes, and when in use, a certain proportion of water is added into the primer on the scene, and the mixture is uniformly stirred so as to obtain the finished product. According to the powdery primer, the problems that a common water-based primer cannot be stored for a long time in a low temperature situation, and is high in transportation cost and low in peel strength, and the like, are solved, and the primer has the following advantages: the primer is blended for use on the scene, reduces transportation cost, and is strong in adhesive strength, environment-friendly and non-toxic.
Description
Technical field
The present invention relates to a kind of waterproof roll base treatment agent, specifically a kind of adhesive waterproof coil powdery base treatment agent.
Background technology
Current adhesive waterproof coil achieves and applies widely in China's buildings waterproof construction, and it has a good application prospect.This kind of coiled material has good low temperature flexibility, adhesive effect is got well and has good self-healing performance, and normal temperature can be constructed, and does not need, with the roasting coiled material of fire, to meet environmental requirement.
But mostly now be water-based base treatment agent with adhesive waterproof coil is matching used, this type of base treatment agent is liquid form because of it, the impact of temperature is subject in storage process, especially when temperature is lower, the phenomenon such as to freeze, affect its result of use, add a large amount of water due to it simultaneously, add transportation cost.As Chinese patent CN101857759B discloses a kind of " base course treating agent used for self-adhesive waterproof coiled material " invented by the applicant, it is a kind of by plurality of liquid mixture, containing water 25-30 part in its composition, is water-based base treatment agent.This base treatment agent solves that time of drying of general pitch class base treatment agent is long, stripping strength is low, thermotolerance and the problem such as poor performance at low temperatures, high VOC content, but find through the application of field practice, because this base treatment agent is liquid, the quality guaranteed period is short, and operating process bothers.Show: when being transported to use scene by production site, need to be filled in bucket, in roping process, especially during long-distance transport, by the impact of the environment such as road bump, bucket easily broken, the seepage of splendid attire base treatment agent, not only increase transportation cost, cause financial loss, and when this aqueous base treatment agent uses in the winter time, the impact by temperature is very easily freezed, the base treatment agent freezed needs to heat and melts and could use, and adds labour intensity to user.Base treatment agent physical and chemical performance simultaneously after freezing-thawing changes to some extent, increases set time, has slackened the serviceabilitys such as bonding force.
Summary of the invention
Goal of the invention of the present invention is the deficiency high for prior art liquid base treatment agent transportation cost, easy to leak, easy freezing affect end-use performance, and provides that a kind of set time is short, weathering resistance is strong, bonding force good, stores the adhesive waterproof coil powdery base treatment agent of convenient transportation.
Realize above-mentioned purpose by the following technical solutions:
A kind of adhesive waterproof coil powdery base treatment agent, the component and the mass fraction that form this base treatment agent are as follows: superpolymer latex powder 70 ~ 80 parts, thickening material 4 ~ 5 parts, photostabilizer 0.6 ~ 0.8 part, defoamer 3 ~ 4 parts.
Preferably, described superpolymer latex powder is: ethylene-vinyl acetate copolymer latex powder, ethene-vinyl acetate-tertiary monocarboxylic acid ethylene copolymer latex powder or vinyl acetate-vinyl versatate copolymer latex powder.
Preferably, component and the mass fraction of base treatment agent are as follows: ethylene-vinyl acetate copolymer latex powder 75 parts, thickening material 5 parts, photostabilizer 0.7 part, defoamer 3 parts.
Preferably, described thickening material is Natvosol, carboxymethyl cellulose or diatomite.
Preferably, described defoamer is SOLID ORGANIC silicon defoamer.
Compared with prior art, the present invention forms the base treatment agent of solid powdery by superpolymer latex powder, thickening material, photostabilizer, defoamer etc. being organically combined, overcome the problem that the existing liquid base treatment agent quality guaranteed period is short, transportation cost is high, its remarkable advantage is, without any loss in this base treatment agent transportation, transportation cost is low, and storage cycle is long.Because this base treatment agent is powdery, weatherproof, can use at any time at the construction field (site) and configure at any time, its physical and chemical performance does not change, and construction rear curing time is short, bonding strength is high, safety and environmental protection.
